Product Description

i Key Feature


Why Does Crawl Space Ventilation Matter?

- Approximately 50% of air on the first floor of your home comes from your crawl space. That means any pollutants, unwanted odors, or whatever reptiles may bring into your crawl space is seeping into the air and parts of your home where your family spends quality time together.

- To solve these problems, crawl space ventilation is key. Crawl space fans will simply pull moist and stale air out of the crawl space so that fresh air from outside can enter, which achieves air exchange that can improve air quality and reduce moisture.
