New Homes & Renovations: Moisture Control Before Problems Begin

Moisture is always an issue in the case of any house. And while you will encounter moisture in older homes, there’s new home moisture as well. It might seem uncomprehensible in the beginning, but the truth is that you will need to keep the moisture levels under control as much as possible. That’s why it makes sense to figure out how to start building moisture control, and doing that accordingly is going to be a crucial aspect. But as expected, it’s totally worth considering, and you will surely appreciate the results. Why new builds often suffer from high humidity? There are many reasons why you encounter high humidity levels in new buildings. For example, there’s moisture in building materials, which might not seem problematic at first, but it does add up. Also, construction workers focus on energy efficiency and modern homes have all kinds of things like weather barriers, air sealing and so on. Those things help save energy, but the downside is that you are trapping humidity inside, which could end up being problematic. Additionally, you could have a HVAC system that’s not yet optimized, and that means the humidity is quite high and it can be rather difficult to keep that under control. Plus, the landscaping and exterior grading could still be settling, in which case water is not draining properly. Needless to say, there can be a whole lot of reasons why you are dealing with moisture problems. Whether it’s a new home or you have post-renovation humidity, clearly you have to tackle those things early on and manage them the best way that you possibly can. How to monitor humidity after construction? The great thing here is that you can indeed monitor humidity after construction with pretty good results. With that being said, there are different methods you can use in here, and you can obtain some excellent results when doing so. Using a digital hygrometer is a good idea, because it can monitor the humidity levels in a variety of places. You can also track the RH levels daily for the first 90 days, as humidity spikes can appear during the night, after rain or when the HVAC unit is out of its regular cycle. Then, there are smart home monitoring solutions that include Wi-Fi humidity sensors. And of course, you can also check for some early warning signs, as even the mild symptoms can indicate humidity problems. Condensation on windows, musty smells, hardwood cupping, peeling paint, creaking, all of those can be inherently important and a thing to consider. Early-stage prevention During the early stages, it can be a very good idea to find effective ways of preventing the moisture buildup, and there are plenty of methods to consider here. A very good option is controlled ventilation, where you can use heat recovery ventilation, energy recovery ventilation or even exhaust fans. Additionally, you can go the accelerated drying route. You can run the HVAC all the time for around 2-3 weeks, and also use portable fans in the closed-off rooms. Plus, keeping the interiors dry to help with air circulation is important. You should also focus on sealing the moisture entry points. These can be gaps around the plumbing penetrations, air leaks near the windows, missing exterior caulking or even slab edges that were not sealed. With that in mind, you can also use vapor barriers as well as good insulation. All these things help immensely, and they will provide a more consistent result, along with extraordinary value every single time. They are great for laundry rooms, bathrooms, crawl spaces or basements as well. Choosing dehumidifiers for post-renovation drying Dehumidifiers are the best option you can use to deal with the post-renovation humidity. As we can imagine, humidity levels can be on the high side, so you must find a way of handling that process and make it as cohesive as it can be. Which is where the need for a good dehumidifier comes into play. In order to find the right dehumidifier, it makes sense to determine the space size and also the moisture load, where possible. You should also consider features like automatic defrost, integrated humidity control, low temperature operation or continual drainage. Needless to say, a high extraction rate is very much necessary here. And of course, it also makes sense to have adequate placement, you should have it 12 inches away from the wall or other obstructions, if possible. Common mistakes A lot of people make mistakes when it comes to humidity in new homes. And these will vary quite a lot, based on the situation at hand. Over-ventilation is an issue, mainly because opening the windows during humid days will bring in even more moisture. Also, undersizing the equipment is also a problem, instead you want to size up, just to be on the safe side as much as possible. Another mistake you can make is to ignore basement moisture, which is going to become quite the issue in the long run. And to that we can also add other mistakes like turning off the HVAC way too soon, not to mention assuming that the moisture will just go away. It doesn’t. It will still be there in the long run and it can lead to mold, blistering paint, damaged floors, warped wood and many other things similar to that. It just makes more sense to approach this with a true focus on quality and avoiding mistakes is always going to make things better than expected. Cost-benefit of proactive moisture management Does it matter if you eliminate new home moisture? Yes, because you can end up saving a lot of money. For example, mold remediation is well over $1500, then we have floor replacement, drywall repairs, cabinet replacement and many others, all of which add up. Preventing these problems by getting a dehumidifier, hygrometer and performing some ventilation upgrades is much cheaper. You will spend around 10 times more for repairs, maybe even more so. That’s why you have to be very careful when it comes to how you manage moisture. Invest in a dehumidifier and the right equipment, as it conveys a much better return on investment!

Humidity & Dust Control for Workshops and Industrial Spaces

One of the main challenges that a lot of industrial spaces and workshops have comes in them form of workshop humidity control. Yes, dust and high humidity levels can tend to be very problematic, and something you want to avoid. Not only can they hamper products and items stored inside the warehouse, but they also lead to issues for workers. That’s why you always want to find great strategies to circumvent that, like using an industrial dehumidifier. Why humidity and dust are major issues in workshops? Generally, water and dust tend to be problematic for industrial spaces. Wood absorbs moisture, metal rusts, electronics get damaged, paint and finishes will fail completely if the moisture levels are too high. The same thing can be said when it comes to dust. Usually, dust will lead to respiratory problems, and suspended dust can be combustible, especially in the case of woodworking. If the company uses sensors or calibration tools, their accuracy will be affected by dust. In general, you want to keep dust and humidity levels in a workshop at a low level, where possible. That can circumvent issues, and provide better overall results. Effects on materials, tools, and worker health Will dust and humidity bring worker health issues? Of course, because excess humidity always leads to fatigue, discomfort and respiratory problems. Not only that, tools that are electronic in nature will stop working most of the time. And to make things even worse, metal components can get corroded, which is the last thing you want. Even lubricants will break down faster if the environment they are in is very humid.Plus, if the space has wood, those wooden products will distort, contract or expand, depending on the situation at hand. And the same thing is valid when it comes to dealing with surface cracking or grain problems. Even the colors won’t be absorbed properly most of the time. You need to find a way of addressing this problem, otherwise you will encounter a variety of challenges that are very hard to face. Integrating dust collectors and dehumidifiers for balanced air quality What you want to do when you have an industrial environment with high humidity levels and dust is to use dehumidifiers and dust collectors. The role of a dust collector is to capture airborne particles via filters, ducts or hoods. And then you have the industrial dehumidifier that will remove moisture from the ambient air. Both of them are ideal if you want to get rid of unwanted dust particles and high humidity, so keep that in mind.Of course, you do need to think of other things as well, including: Separate the high moisture zones when you can, so you can have better control over humidity levels Additionally, it makes sense to coordinate the ventilation rates in order to balance pressure Design the ducting system in such a way that the clean/dehumidified air circulates across all areas in a uniform manner. Installing HEPA stages and pre-filters is always going to help trap fine dust, something that’s extremely useful. Practical layout ideas When it comes to ducting, try to use the shortest path principle, since the longer the ducts are, the more obstructions and issues arise. Calculate the static pressure and focus on branch balancing where you can, as it will help you quite a lot. Go with a multi-stage filter setup too. You should have a coarse pre-filter, a fine filter and a HEPA or even a cartridge filter. As for the dehumidifier, it makes sense to place it in a central spot and you can use ducted industrial solutions if you have a large facility. For those cases when we talk about a localized workshop, using a portable unit can actually help, and it could improve the experience. Maintenance and safety best practices You should make sure that you keep the humidity and dust levels under control. Here are some ideas: If you use a dust system, try to empty the collection bins every day and inspect the ducts/joints every month. Replacing the filters or at least cleaning them is also of pivotal importance. And yes, ground all the metal ducting, as it will allow you to prevent any explosion and static discharge, which could become an issue later on. For dehumidifiers, you want to clean the filters and condenser coils every month. You also want to check the drainage systems and inspect gaskets/seals where possible, so there are no air leaks. And of course, you do want to schedule the calibration of humidistats where you can, so the readings can stay accurate. Lastly, make sure that you keep the health and safety compliance. Ensure that all the fire suppression systems are functional, stick with the OSHA dust exposure limits, and use PPE equipment where possible, to limit any side effects or downsides. Cost-saving and energy-efficient strategies There are also a few other things that you can do to save money and lower energy costs. For example, you want to clean filters and lubricants, along with having smart humidity control. Using variable speed drives will also help quite a lot, and it does help to have heat recovery, along with good air recirculation. All of that stuff is super important, and it will affect the overall costs. Plus, even simple things like the equipment selection or using renewable energy, those can end up making a huge difference in the long run. Conclusion We believe it’s a very good idea to try and keep humidity and dust levels as low as possible in industrial environments. These tips and ideas shown above will always be useful, especially in these very specific situations. Once you start implementing such solutions, it will be not only easier to manage, but you can also avoid a lot of challenges and potential issues. Once you handle that appropriately, it will bring in a much better experience. Plus, you do want to keep the equipment and people safe, and this is the right approach!

Do Dehumidifiers Really Improve Indoor Air Quality?

Purchasing a dehumidifier sounds like a great idea, mainly because it allows you to focus more on eliminating moisture from the air. As we know, high levels of water in the air can lead to mold, not to mention it can even affect your health as well. With that in mind, the dehumidifier air quality is always better, and there are many benefits that come from purchasing such a product. That’s why we are here to help you identify how/if a dehumidifier can improve the air quality. The link between humidity and air quality Relative humidity is seen as the percentage of moisture found in the air which is relative to the maximum water vapor the air can hold at a given temperature. It’s recommended to keep it around 30% to 50% for most living spaces. If it’s under 30%, the air will feel dry, and your respiratory irritation is increased. If it’s over 50% for example, that encourages mold growth, dust mites appear and there’s more condensation. How excess humidity affects allergens and respiratory health? Is it problematic if you have a very high humidity level and it certainly affects your health. Simply put, excess humidity leads to dust mite formation, and mold exposure can also trigger allergic reactions, non-allergic irritation or it can even exacerbate asthma, which is something to take into account here. Plus, a high humidity level can lead to airborne particles that settle faster, not to mention it can also contribute to resuspension of settled dust. Plus, a high humidity levels brings unwanted odors, it encourages mold growth, etc. Simply put, this will affect the indoor chemistry, which is something you want to take into consideration. Think about humidity and allergies, and then you will quickly realize that if you live in a place with high humidity, you tend to have way more allergic reactions than normal. How dehumidifiers improve air freshness and reduce mold? A dehumidifier is one of those investments that can be very much worth it, since they lower mold appearances, not to mention you will be able to reduce musty odors, reduce condensation or improve the preservation of materials. Once you use a dehumidifier, you will also be able to eliminate most of the dust mite allergens, improve your comfort, while also not dealing with respiratory discomfort anymore, something you have to take into consideration. However, there are things that a dehumidifier won’t do. It won’t remove the fine particulates nor will it remove chemical pollutants. It’s also not going to fix any water intrusion, which is crucial to take into account. In the end, it’s just a much better idea to try and use a dehumidifier because it does allow you to lower humidity levels properly. With that being said, you have to be realistic when it comes to expectations and what it can do. It won’t solve all air quality problems, but you will certainly see improvements, and that matters immensely.If you do acquire a dehumidifier, a very important thing is to check the pints per day or liters per day that it can extract from the room. Also, you may want to check the coverage area, if it has an auto-humidistat as well. And of course, things like the noise levels, drainage options and energy consumption will matter just as much. How to monitor humidity and air quality? These days, monitoring the air quality and humidity is not that difficult. You have a vast array of products you can access, and these are quite impressive to use. A digital hydrometer, smart monitor and moisture meter for materials would be a great option for humidity monitoring. If we talk about tools for air quality monitoring, it does make sense to opt for particle sensors, VOC sensors, but also CO and CO2 sensors or dedicated air quality monitor products, if you want. Combining dehumidifiers with air scrubbers or HEPA filtration You can choose to use a dehumidifier with an air scrubber or even with HEPA filtration systems. The great thing is that all of these will have their benefit. The dehumidifier will reduce the source creating odors and allergens. The HEPA filter will help remove airborne particles, dust, spores and so on. And then, you have the air scrubber that will reduce VOCs and microbes. You can opt for configurations that integrate dehumidifiers with the HVAC system, or you can use a dehumidifier with a portable HEPA air purifier. These are totally up to you, and in the end, you will find the experience itself to be one of the top things out there, that’s for sure. Simple step-by-step setup guide First, the thing you want to do is to identify the target space and also the measure baseline. You can use a hygrometer and then record the RH as well as any spikes that happened over multiple days. Then, choose the right dehumidifier from Abestorm. Pick one based on the room size and capacity, temperature conditions, drainage, but also humidistat and other features. Knowing all the details can help immensely, and it will help make the process much easier. After you buy the right dehumidifier, you will need to position it around 6-12 inches from the walls or furniture. And then, of course, you want to select the target humidity. 45% is healthy indoor humidity, because you can avoid dryness and also mold or dust mites. If you have allergies, 40% to 45% is usually the best option. We highly recommend adding a HEPA air purifier in the room, especially if it’s frequented very often. As you start doing this, you need to continually monitor and adjust, as it will help keep things under control. Naturally, you also want to maintain the unit regularly. Clean the water tank, replace filters, inspect the drip pans and coils, and also service the dehumidifier annually, also do the same for the HVAC as well. Conclusion We highly recommend taking your time and finding the right dehumidifier that fits your needs and requirements. Our team at Abestorm is always here to assist, and we provide our customers with consistent, professional results every single time. All you have to do is avail the opportunity, browse our store and pick the right dehumidifier that fits your needs. Rest assured that there’s great value to be had for a variety of pricepoints, depending on your budget!

Fan Vs Blower: Understanding the Technical Differences

Confused between a blower and a fan? No worries! Both move air, but the major difference lies in pressure and purpose. Fans are great for moving large volumes of air at home, and blowers can push air through ducts to target focal areas with higher pressure. However, there is much more than this, and understanding how each works, their applications, and which one suits your needs can save you money, energy, and frustration. So, here you go! The Difference Between Fans and Blowers People usually ask, 'Are fans and blowers the same?' No! A fan has rotating blades, such as axial, cross-flow, or centrifugal, that move large volumes of air at low pressure. Fans are ideal for general air circulation, climate control, and comfort use at home. They can be ceiling fans, crawl space vents, computer case fans, or air-cooled radiators. A blower can move air with higher pressure and force than a fan. It uses an impeller to push air through a narrow space. This is perfect for tasks like drying, ventilation through ducts, or removing dust and debris. One misconception is that people usually use the term blower fan, thinking it refers to a special type of device that combines features of both a blower and a fan. In reality, blowers and fans are two separate devices with different designs, functions, and purposes. Pressure Ratio The American Society of Mechanical Engineers (ASME) presents the difference between a fan and a blower by pressure generation capability: ● Fans: Pressure ratio ≤ 1.11 (minimal compression, high-volume flow) 1512 ● Blowers: Pressure ratio 1.11–1.2 (moderate compression, directed airflow) ● Compressors: Pressure ratio >1.2 (high compression for pneumatic systems) Design and Construction Differences Comparing their structural components, a fan has blades, whether axial or radial, to push or accelerate air and often use lightweight aluminum or plastic. Plus, they are cost-effective for low-stress uses. However, blowers have forward-curved impellers inside a casing for efficiency in HVAC and backward-inclined impellers for high-static industrial uses. These are made of cast iron or stainless steel to withstand pressure, heat, and corrosive gases. Technical Performance Comparison Airflow and Pressure Characteristics Parameter Fans Blowers Airflow Volume High volume, low velocity Moderate volume, high velocity Pressure Output Low (< 0.5 psi) Medium (0.5–2 psi) Directionality Omnidirectional, diffuse Focused, linear airstream Noise Level Lower (25–50 dB) Higher (60–85 dB) Mechanical Design & Airflow Generation Fans use blades (axial or radial) that rotate to create low-pressure, broad airflow, like ceiling fans sweep air downward in a wide column. However, blowers employ enclosed impellers (centrifugal or positive displacement) that accelerate air radially. For example, centrifugal blowers in furnaces force air through ducts via centrifugal force. Applications: When to Use Which If you are confused, how do I choose a fan or blower? The answer is simple: fans are ideal for low pressure and broad coverage. You can use the following types of fan: ● For home/office cooling, ceiling fans, pedestal fans, and HVAC vents keep indoor spaces comfortable. ● Electronics cooling, axial fans inside computers and servers, help prevent overheating by moving heat away from components. ● For ventilation, crawlspace ventilator fans, attic fans, and window fans efficiently circulate air and remove moisture or stale air. You can use a blower for high-pressure tasks such as: ● In industrial drying, blowers help quickly remove moisture from cars in washes, etc. ● In material handling, they move powders or grains through pipes using air pressure. ● Combustion systems depend on blowers to provide oxygen into boilers or incinerators to keep flames burning efficiently. Cost, Efficiency, and Maintenance Trade-Offs Purchase and Operating Costs Factor Fans Blowers Initial Cost $20–$500 (lower complexity) $200–$5,000 (heavy-duty build) Energy Use 50–500W 300–5,000W Lifespan 3–7 years 5–15 years Maintenance Minimal (blade cleaning) Bearings/impeller inspections What to Avoid: ● Never use fans for a ducted system because static pressure in ducts reduces fan airflow by up to 60%, but blowers handle resistance better. ● Oversized blowers provide excess pressure that wastes energy and causes noise, so calculate CFM requirements to understand what size ventilation fan you need. Energy Efficiency and Noise Fans are quiet in operation, especially axial models, and are more energy efficient because they consume less power for moving air due to low pressure. They are also ideal for continuous use in homes or offices. Blowers need more energy to generate higher-pressure airflow; thus, they are noisy and take more power. So, if you want quiet and energy-saving performance, a fan is a better choice. 5 Tips to Choose Between a Fan and a Blower These tips can help you make the right choice: Pressure Needs If you are moving air through ducts, filters, or tight spaces, choose a blower! It can deliver high pressure. For open areas like rooms or hallways, a fan works best. Airflow Volume (CFM) Need to move a lot of air gently? Go for an axial fan and if you need high-pressure airflow in compact volumes, a centrifugal blower works best. Environment When dealing with hazardous fumes or flammable gases, use an explosion-proof blower. For bedrooms or in a commercial environment, a quiet DC fan under 35 dB is ideal. Energy Constraints If you are off-grid or want to cut energy costs, low-wattage DC fans or solar-powered options offer efficient airflow without draining power. Durability Demands In an industrial environment that is usually hot, stainless steel blowers resist corrosion and heat. They are perfect for long-term durability. Final Words Fans and blowers both have spinning blades, but they differ in function, design, and application. So, it is important to understand the differences so that you can make a wise decision. After all, aligning your needs with the right technology can ensure efficiency, longevity, and peak performance. I hope this article helps you a lot!

How Long Should You Run Fans After Water Damage? - Your Complete Guide

How Long Should You Run Fans After Water Damage? - Your Complete Guide

Water damage is highly stressful, whether caused by a burst pipe, flooding, heavy rainfall, etc. The consequences can be highly impactful as they lead to structural damage, mold growth, and more. The most common query that exists on the internet is: How long should you run fans after water damage? The simple answer is: run fans for at least 24-72 hours to remove surface moisture and prevent immediate secondary damage. However, this answer does not simplify your problem because water damage varies, and so does the time for the drying process with fans. Let's dig into the details of fan usage according to the extent of water damage restoration. Why Is It Important to Run Fans After Water Damage? Long exposure to water can cause multiple issues because it can seep into the walls, flooring, furniture, and even structural components. If you run fans, it can speed up the evaporation process, help to prevent these risks, and make the water damage restoration more efficient. If water is not dried out quickly, it can cause mold growth within 24-48 hours, weaken wooden structures, and damage drywall. It also leads to long-term odors, indoor air quality issues, and can reduce property value. Best Equipment to Use for Drying After Water Damage ● You can use high-velocity fans or air movers at high speed. ● To extract moisture from the air, use dehumidifiers. ● HEPA air scrubbers are also useful if mold is suspected. These clean the air by removing microscopic contaminants and spores. Factors That Affect Fan Run Time After Water Damage The duration for which you'll need to run fans can vary. Here are a few factors that impact drying time: Extent of Water Damage The volume of water and the size of the affected area matter a lot. For minor spills and damp carpets in which water does not go deeply, 24-48 hours of fan runtime is needed. It applies to surface-level dampness on hard floors. However, in case of flooded basements or major leaks, materials will be heavily saturated, and moisture will deeply penetrate walls, subflooring, and insulation; consistent drying with high-powered fans and dehumidifiers is important. Keep the fans on for at least 5 to 7 days, and sometimes even longer for severely saturated areas. Type of Material Affected Different materials absorb and retain moisture differently, for example: ● Porous materials like hardwood floors, drywall, carpet padding, insulation, and particleboard are highly absorbent. They soak up water deep into their core. They need up to 7 days or more to return to their pre-loss moisture content. ● Non-porous materials like concrete, tile, stone, and metal are less absorbent. Water tends to sit on their surface rather than penetrating deeply. These surfaces dried up quickly, but hidden moisture can stay there, so it also needs quality hours for drying. Humidity Levels Humidity in the air directly affects how much moisture can evaporate from wet surfaces. If the ambient air is humid, the air quickly becomes saturated with moisture. This high humidity slows down or stops evaporation from wet materials because the air can't hold any more water vapor. To manage this, the U.S. Environmental Protection Agency (EPA) recommends using a hygrometer to monitor indoor relative humidity (RH).. For effective drying, the indoor humidity should ideally be maintained below 50%, and often professionals aim for 30-40% RH. If the humidity is too high, use dehumidifiers to pull moisture out of the air. Ventilation and Air Circulation Simply placing a fan in a room isn't enough. For perfect drying, you need to create a strategic airflow pattern using multiple fans or air movers (high-velocity fans). For strategic placement, position air movers low to the ground, pointing at walls, floors, and other wet surfaces. They create a laminar flow that speeds up evaporation. If you have Crawlspace Ventilation Fan, they are best for the rooms to push humid air towards the dehumidifier or out of a window. You also need to open windows and create a cross-breeze with fans to improve air exchange and speed up drying. Ambient Temperature Warmer air can hold more moisture vapor than cooler air. If the temperature is too hot, especially without proper ventilation and dehumidification, it can damage the place and cause material damage like warping or cracking further. So, maintain the room temperature between 70°F and 90°F (21°C – 32°C) for water damage drying. Within this range, water molecules gain enough energy to evaporate more quickly. If the temperature is too low, evaporation will be slow and can increase drying time. Signs That Your Space Is Dry Enough to Stop Running Fans Wondering how to tell when it’s safe to turn off the fans? Here are signs your space is dry: ● The moisture meter reads acceptable levels (10–15% moisture content for wood). ● Surfaces feel completely dry to the touch. ● No musty smell lingers in the room. ● Humidity is below 50%. ● No signs of mold growth (black spots, odor, etc.). Final Verdict- How Long Should You Run Fans After Water Damage? For surface-level drying, keep the fans running for 24–72 hours. If you do not have a suitable fan, consider getting one from Abestorm.com. The complete drying and restoration process can take approximately 7 to 14 days, and severe water damage takes a few months to dry properly. If you are unsure, it’s always wise to call a professional water damage restoration team. They have the tools and expertise to assess hidden moisture and ensure your property is truly dry, not just on the surface. FAQs How long after water damage does mold grow? In 24–48 hours, mold can begin growing in damp environments, and after 72 hours, mold becomes a serious risk, especially behind walls and under floors. So, running fans immediately after water damage is essential to preventing this. Can I turn off the fans at night while drying water damage? No, it’s best to run fans 24/7 until the area is fully dry. Turning off fans at night slows down the evaporation process and increases the risk of mold growth, especially in humid environments. How do I know when the area is completely dry? Use a moisture meter to test the materials. Dry wood should read between 10% and 15% moisture content. Additionally, the room should feel dry to the touch, have no musty odor, and maintain a relative humidity below 50%. Is it safe to stay in the house during the drying process? Yes, in most cases, it is safe if there is clean water that caused the damage. However, for gray or black water contamination, it's safer to stay out until professionals complete sanitization and drying.

How Long Does Crawl Space Encapsulation Last? The Ultimate Guide

How Long Does Crawl Space Encapsulation Last? The Ultimate Guide

The ultimate solution to protect your home from moisture, mold, and rising energy bills is to go for crawl space encapsulation. However, how long does crawl space encapsulation last? A well-installed encapsulation system can last up to 25 years, especially when high-quality materials are used and proper maintenance is provided. But here’s the catch: not all encapsulation systems are created equal, and their longevity depends on far more than just the plastic barrier. So, spare a few moments to read more. What Is Crawl Space Encapsulation? Crawl space encapsulation is the process of sealing the dirt or concrete floor and walls of your crawl space. It creates a fully controlled environment and joins the crawl space to your home’s conditioned air system. The purpose is the protection against external moisture, pests, and air leaks by using: ● Vapor barriers (plastic sheeting, 12–20 mil thick) on floors and walls. ● Closed-cell spray foam or rigid foam board insulation on walls and piers. ● Dehumidifiers are used to maintain humidity below 50%. ● Sealed vents and access points to block outside air. Factors That Affect Crawl Space Encapsulation Lifespan Here are a few factors that decide the longevity of the crawl space encapsulation: Material Quality Always use high-quality materials such as vapor barriers under 12 mil usually tear from sharp rocks or even foot traffic. However, 20-mil reinforced barriers offer long-term protection. Even professional-grade sealing tapes and adhesives prevent seams from pulling apart over time. Installation Quality Hire professionals for crawl space encapsulation installation because common issues usually occur, such as gaps around support pillars, plumbing penetrations, or foundation vents. A professional installer, ideally certified by organizations like the Basement Health Association (BHA), ensures a smooth process and a longer lifespan than DIYers. Maintenance Routine A biannual inspection can identify small issues, such as torn sections or failing tape, etc, before they become costly problems. Cleaning or replacing air filters on dehumidifiers, inspecting drainage systems, and checking for pests are simple steps that add years to your encapsulation's life. Humidity Control Moisture can destroy your crawl space encapsulation system. In humid regions, crawlspace ventilation fans or dehumidifiers are essential. Without active humidity control, condensation can form on barrier surfaces, which can welcome mold growth and impact encapsulation longevity. Flooding & Water Intrusion Standing water can make vapor barriers, lift tape edges, and saturate insulation weak. To deal with this, encapsulation systems should include French drains, sump pumps, or other drainage solutions to remove water and prevent damage from moisture. Advantages of Encapsulating Your Crawl Space You can simply control moisture, prevent mold, rot, and structural damage. Plus, it can block rodents, termites, insects, and keep allergens and musty air out. Not to forget energy efficiency, because encapsulation can stabilize house temperature and lower energy bills, and also enhance your home value. Signs You Need Encapsulation or Repairs Here are a few warning signs that you should always look for: ● Musty or moldy odors in your home. ● Visible mold, mildew, or wood rot. ● Continuous dampness or standing water. ● High indoor humidity or rising energy bills. ● Pest infestations signal entry points. ● Damaged, loose, or peeling barrier material Average Lifespan of Encapsulation Components Component Lifespan Factors Influencing Longevity Vapor barrier 15–25 years 26 Thickness (20 mil > 12 mil > 6 mil), foot traffic Spray foam insulation 20+ years 1 UV exposure (minimal in crawl spaces) Dehumidifier 10–15 years 18 Brand quality, filter maintenance Dimple mat/drainage 20+ years 1 Flooding, soil shifts Sealing tape 15–20 years 1 Humidity control, initial adhesion quality How to Maximize the Lifespan of Crawl Space Encapsulation? You need to follow a few maintenance tips to ensure encapsulation longevity up to 25 years: ● Hire professionals for inspection at least once or twice a year; more if in wetter regions. ● You need to patch tears quickly using high-grade tape. ● Keep dehumidifiers clean and change the filter regularly. ● Service sump pumps and drainage systems annually. ● Protect the barrier from damage and use mats or sleds for crawling in the space. What is the Cost of Crawl Space Encapsulation? Crawl space Encapsulation costs range from $5,500 on average, with possible costs between $1,500 to $15,000, depending on size, existing damage, and features. ● DIY cost: $1,000–$4,000 (variable quality). ● Professional cost: $2–$10+ per sq ft or $5,500 base. ● Additional: inspections, waterproofing, and permits may add $100–$7,000 more. Abestorm Crawl Space Fans That Complement Encapsulation!

What Size Ventilation Fan Do I Need

Proper ventilation is important for maintaining indoor air quality, preventing mold, and improving health. For this, the ventilation fan works best, but what about the right size? Whether you are remodeling your bathroom or upgrading your kitchen range hood, installing undersized or oversized fans leads to many problems. If you are wondering what size ventilation fan do I need, this guide helps you make an informed, cost-effective decision that pays off for years to come. What Is CFM in Ventilation Fans? CFM stands for Cubic Feet per Minute and is the standard unit used to measure how much air a fan can move per minute, and selecting the right CFM ensures efficient ventilation. It tells you how many cubic feet of air the fan can move in one minute (CFM), which is essential when comparing different types of vent fans like ceiling-mounted, inline, or wall-mounted models. If the CFM is too low, the vent fan won't ventilate properly, leading to mold growth, and if the CFM is too high, it can result in unnecessary operating costs and a noisy environment. To calculate the right CFM for vent fans, here is the formula CFM = (Room Volume × ACH) ÷ 60 Where: ● Room Volume = Length × Width × Height (in feet) ● ACH = Air Changes per Hour (e.g., 8 for bathrooms, 15–20 for kitchens) ● 60 = Number of minutes in an hour (to convert hourly air volume to per minute) How to Calculate the Correct Ventilation Fan Size? For optimal air circulation, you have to follow these steps to calculate the ideal ventilation fan size according to the room dimensions: Step 1: Calculate Room Volume For this, calculate: Room Volume (cubic feet) = Length × Width × Height If a bathroom measuring 10 ft x 8 ft with an 8 ft ceiling, it will be: Volume = 10 × 8 × 8 = 640 cubic feet Step 2: Determine Required Air Changes (CFM) The Home Ventilating Institute (HVI) recommends at least 8 air changes per hour for bathrooms. Convert that to CFM with this formula: Required CFM = (Room Volume × 8) ÷ 60 Using the above example: CFM = (640 × 8) ÷ 60 ≈ 85 CFM Step 3: Add CFM Based on Bathroom Fixtures For bathrooms over 100 sq. ft, consider additional CFM for each fixture: Fixture Additional CFM Toilet +50 CFM Shower +50 CFM Bathtub +50 CFM Jetted Tub +100 CFM If you are having a large bathroom with a toilet, shower, and jetted tub: Total CFM = Base CFM + 50 + 50 + 100 = Base + 200 CFM Get the best ventilation fans from Abestorm, and their team is cooperative enough to explain to you the ventilation fan size according to your space. Bathroom Ventilation Fan Sizing Guide If you're still unsure, check out our guide to choosing the best bathroom ventiliation fans for your specific space and needs. Here’s a quick reference to help you size your bathroom fan correctly, ensuring optimal ventilation and moisture control: Bathroom Size (sq. ft.) Recommended CFM Up to 50 50 CFM 51–100 1 CFM per sq. ft. Over 100 Add CFM based on fixtures For ceilings taller than 8 feet, adjust room volume using the actual ceiling height in your calculation. Kitchen Range Hood Ventilation Requirements Kitchen fans (range hoods) are necessary to remove smoke, grease, steam, and cooking odors. Their sizing depends on stove type and cooking habits. General CFM guidelines include: Cooktop Type Recommended CFM per Linear Foot Electric Stove 100 CFM Gas Stove 150 CFM Here is how to size a kitchen range hood: Suppose you have a 30-inch (2.5-foot) gas cooktop, then the required CFM will be: 2.5 × 150 = 375 CFM When to Increase CFM? ● Frequent high-heat cooking, like wok use, frying. ● Long duct runs or multiple bends ● Undersized ducts (match duct diameter to fan output Tip: Always vent kitchen range hoods outside for maximum efficiency. Ventilation Fan Noise: What Are Sones? Ventilation fan noise is measured in sones, where a lower rating means quieter operation. Sones Rating Noise Level <1.0 Very quiet (rustling leaves) 1.0–2.0 Quiet (like a fridge) 2.0–3.0 Moderate (office background) >3.0 Loud (like TV or conversation) For bathrooms, opt for fans ≤1.0 sones for a peaceful ambiance. Factors That Affect Ventilation Fan Performance Beyond Room Size Ventilation needs also vary depending on the space being ventilated. For example, areas like attics or basements may require crawlspace ventilation fans to manage moisture and airflow effectively. Choosing the right CFM is not enough; knowing other elements are also important because they also reduce a fan’s effectiveness: Ductwork Resistance Each 10 ft of 4" duct adds 0.1–0.3 inches of static pressure (SP); elbows, caps, and filters add up to 0.15 SP each. Solution: If the duct run exceeds 20 ft, either: Upgrade to 6" ducting, increase CFM by 20% to compensate Static Pressure (SP) SP is the resistance air faces as it moves through the system. ● Bathroom fans handle 0.1–0.4 inches w.g. ● A 300 CFM fan at 0.5 SP may only deliver 210 CFM. ● Always check the fan’s performance curve at your expected SP. Sone Rating Noise levels matter especially in quiet areas like bedrooms or home offices. ● 1 sone = Quiet bathroom fans with a low sone rating are ideal. ● 3 sones = normal conversation ● ENERGY STAR sets limits: ≤90 CFM fans: Max 2.0 sones and 201–500 CFM fans: Max 3.0 sones Local Climate In hot, humid states like Florida, Louisiana, you’ll need 20% more CFM to combat heavy moisture. Dry zones like Arizona may need less. Ceiling Height For ceilings over 8 ft, apply this adjustment: Adjusted CFM = Base CFM × (Ceiling Height ÷ 8) Example: 100 CFM × (12 ÷ 8) = 150 CFM Final Checklist Before You Buy Before purchasing your exhaust fan, verify these essentials: ● Calculated CFM using room volume, fixture count, and ceiling height ● Duct size & length are compatible with the desired CFM. ● Some ratings are suitable for the room type (≤1.0 for quiet areas). ● Check wiring and circuit requirements, like heat lamps often need a separate circuit. Final Thoughts: Get the Right Airflow, the First Time Proper ventilation fan sizing is important for the protection of your health, home, and investment. A well-sized 110 CFM fan, installed with proper ducting, minimal bends, and correct placement, can perform better than a 200 CFM fan that's poorly installed. So, take 15 minutes to measure your space, crunch the numbers, and evaluate ductwork constraints. I hope your query: What size ventilation fan do I need? Will be solved!

Crawl Space Vent Fans: Are They Worth It

Some reports claim that over 60% of the air you breathe on the first floor of your home comes from the crawl space. Imagine if that space is damp, musty, or contaminated, what will be its effect on your health? As a solution, homeowners go for the crawl space vent fans, but are they truly effective, or just a temporary fix? These confusions cause hesitation in buying a vent fan. Therefore, it's time for a reality check. Dig into the pros and cons of a crawl space vent fan before making a final decision. What Is a Crawl Space Vent Fan and What Is It Used For? A crawl space vent fan is an electrically or solar-powered fan that is installed in crawl space vents to circulate air, preventing stagnant moisture buildup actively. Unlike passive vents, which rely on natural airflow, vent fans forcefully push out humid air and fetch in fresh air, improving overall ventilation. A crawl space vent fan is installed for: ● Moisture control by preventing condensation. ● Remove odor and unpleasant smell caused by standing water. ● For air quality improvement by removing radon or VOCs. ● Reduces extreme temperature variations in HVAC ductwork or plumbing. ● Stops long-term structural damage due to wood rot and corrosion. Pros of Crawl Space Vent Fans Those who ask 'what are the advantages of crawl space vent fans?' can read down here: Actively Reduces Crawl Space Humidity and Moisture Mold growth, wood rot, and structural damage are promoted by excess moisture. However, AbeStorm crawl space vent fans have built-in de-humidistats with high-CFM ratings to remove humid air and draw in drier outside air. This constant air exchange helps maintain the relative humidity below 60%, the threshold recommended by the EPA. Prevents Mold, Musty Odors & Pests The crawl space fans help create an environment that's unfriendly to mold and pests by maintaining balanced airflow and reducing excess humidity. This ventilation keeps musty odors away and discourages insects and rodents that thrive in damp conditions. So, get the complete protection for your home's structure and indoor air quality. Improves Indoor Air Quality for Your Entire Home If that air is contaminated with radon, VOCs, or biological pollutants, it can impact respiratory health. Then, how to ventilate the crawl space to prevent radon? Simple! Get ventilation fans that help mitigate this by expelling contaminated air and ensuring a continuous flow of fresh air. Some models include filters to help trap particulates and improve air quality. Energy Efficiency With Smart Features One of the standout benefits of using crawl space ventilation fans is their energy efficiency. These fans are equipped with smart humidity and temperature sensors. With these features, the fan operates only when needed, which can reduce unnecessary power consumption.

You can install most models within an hour without professional help. It is the best hassle-free upgrade for better crawl space ventilation and moisture control. Cons of Crawl Space Vent Fans The picture has another side too! Here are the disadvantages of vent fans: Not Ideal for Extremely Humid Climates No doubt, vent fans can reduce humidity, but in hot and humid regions, especially in areas with high humidity (above 60% RH), they can pull in more moisture than they remove. When warm, moist air enters a cooler crawl space, it can condense on wood, pipes, and insulation. Not a Substitute for Encapsulation or Sealing Vent fans can help, but they are not a complete solution if your crawl space lacks a vapor barrier, proper drainage, or sealing. It cannot alone solve persistent moisture problems. Using a vent fan without addressing these core issues may only provide temporary relief. Noise Level in Some Models Though most modern crawl space fans are designed for quiet operation, some units may produce noticeable noise, especially if installed near living spaces or improperly mounted. The best approach is to ensure that you get a quiet crawl space fan and check specs like dB rating for low decibel output. Improper Installation Can Reduce Effectiveness If you do not install crawl space fans correctly, like with poor positioning or no coordination with vapor barriers or sensors, they may do little to improve air quality or moisture levels. That’s why it’s important to follow the manufacturer’s guidelines, especially when using smart features. Final Words Your crawl space may be out of sight, but it should never be out of mind. A high-quality crawl space ventilation fan is a worthy investment in your home’s health, efficiency, and longevity. Just keep in mind where you are living because the climate and local humidity levels play an important role in choosing the right ventilation strategy. If you are ready to protect your home from mold, rot, and costly structural damage, explore AbeStorm’s trusted lineup of crawl space fans. FAQs Should a crawl space be vented or not? In hot, humid regions, venting may pull in moisture-laden air, worsening mold and humidity issues, so encapsulation and dehumidification may be better. In dry or temperate areas, venting with a controlled crawl space fan can help prevent condensation and mold. How long should a crawl space fan run each day? Smart crawl space fans with humidity sensors run when needed. On average, 2–4 hours per day may be sufficient. However, in humid climates or summer months, daily runtime may increase. What is the ideal humidity level for a crawl space? Experts recommend keeping crawl space humidity levels between 30% and 50%. Levels above 60% can lead to mold, wood rot, and pest infestations. Smart fans like those from AbeStorm activate automatically when humidity exceeds safe limits. Can a crawl space vent fan replace a dehumidifier? Not always. A crawl space fan is great for moderate humidity control and ventilation, but if you are dealing with constant moisture, flooding, or high relative humidity, a dehumidifier is required. In many cases, both systems work best together.

Do Houses Without AC Systems Need Ventilation

Do Houses Without AC Systems Need Ventilation Absolutely. Poor ventilation traps musty odors that become unbearable. This is especially critical during Southern US summers, when humidity makes homes feel oppressive. Without proper airflow, you'll face peeling drywall, warped cabinets, and potential health issues. This guide explains why ventilation is essential for AC-free homes and how to maintain healthy indoor air. Understanding Ventilation in Homes Ever notice how closed rooms get stuffy with stale air? That's poor ventilation. Simply put, ventilation is the process of bringing fresh air in while pushing contaminated air out, like your home's breathing. Opening windows and doors is the simplest way to ventilate the room. You can also use a ventilation fan to bring fresh air into the room and send out the "bad" air in the house. These "waste gases" include: Carbon dioxide from breathing Cooking fumes and odor Chemicals (formaldehyde, VOCs) from furniture and cleaners Humidity from showers and daily activities Allergens like dust and pet dander Bacteria and viruses Why Ventilation Matters (Especially Without AC) 1. Health ProtectionStagnant air concentrates harmful substances. Proper ventilation reduces triggers for respiratory issues, allergies, and long-term health risks—a critical fact: Gas/propane stoves cause up to 19,000 US adult deaths annually. Air purifiers can't eliminate carbon monoxide. 2. Moisture ControlThe biggest challenge is in humid regions like the South. Daily activities (showering, cooking, breathing) pump moisture into your home. Without ventilation: Mold grows on walls and ceilings Paint peels Wood structures rot Structural damage occurs 3. Oxygen MaintenanceVentilation prevents carbon dioxide buildup that causes headaches, dizziness, and fatigue. 4. Odor ReductionContinuous airflow removes stale smells (though it doesn't cool like AC). Warning Signs of Poor Ventilation Persistent musty smells Condensation on window Visible mold growth Increasing allergy symptoms Difficulty breathing indoors If you notice these, act immediately. For severe cases, install exhaust fans or dehumidifiers. Ignoring it often leads to $2,000+ mold remediation bills. Passive Ventilation: Natural Airflow Solutions Use physics to move air without electricity – ideal for AC-free homes. How it works: Stack EffectWarm air rises and escapes through high vents, pulling cool air through low openings. Wind-Driven VentilationWind forces air into your home (windward side) and pulls it out (leeward side). For example, they oriented the air intake windows toward the sea breeze in a Miami beachfront home. Benefits of Passive Ventilation: Reduces energy costs Lowers carbon footprint Improves indoor comfort Enhances air quality Requires minimal maintenance The stack effect is another natural way to cool a home. As warm air rises, it causes airflow between different levels in a building. Careful design is essential for this to work well, especially in multi-story houses. Adding shading features also helps with airflow. Shaded spots tend to be cooler, which encourages natural air circulation. Eaves and overhangs can be effective options. The materials used in buildings also influence passive ventilation. Breathable materials like bricks and stones help with natural air exchange, and properly sealing gaps and joints can improve control over air movement. If you do this right, you'll enjoy a cooler home and save on energy costs. Difference Between HVAC and Air Conditioning HVAC does more than just cooling – it covers heating, ventilation, and air conditioning to manage your whole indoor environment. Air conditioning focuses only on cooling things down. People often confuse the two because they look similar, but here's the key difference: HVAC combines heating units, ventilation fans, and cooling components in one system for year-round control. Air conditioners usually work alone or with basic fans. When choosing what's right for your home, consider your climate—HVAC for complete temperature management and AC if you just need relief from heat. Ventilation Without AC: Strategies for Maintaining Comfort Homes without AC need other ventilation methods. These keep indoor comfort and air quality. Design homes to use natural breezes. Cross-ventilation lets air flow through rooms, lowering indoor heat. Building features help ventilation. Big windows and well-placed vents move more air, and skylights add extra air exchange paths. Fans matter when natural wind fails. Some devices copy natural breezes with changing speeds. Smart home tech adjusts ventilation automatically. Systems respond to temperature and humidity shifts. Change daily habits for comfort. Wear season-friendly clothes and bedding. Cook outside to avoid indoor heat and dampness. There are different strategies that can replace AC. Boosting Airflow with Fans 260CFM Ventilation Fan works best in large rooms, creating steady breezes that make heat bearable. Add exhaust fans in kitchens and stuffy corners to push out hot air. Use adjustable-speed models to control airflow as weather changes. Plants: More Than Decor Plants pull toxins from the air and release oxygen, acting as natural purifiers. Place leafy varieties near windows – they cool through evaporation, especially helpful in dry climates. Water features like tabletop fountains add moisture to dry air. Combine plants and water for a fresh indoor oasis. Conclusion Get the air moving right in your AC-free home—crack those windows for healthier living, lean on nature's free cooling to save cash and the planet, and plan smart to stay comfy without cranking up energy bills.
