From Damp and Musty to Dry and Comfortable in Just 48 Hours

Abestorm 260CFM Crawlspace Ventilation Fan | NeatyFresh 260

Homeowner Mark noticed a persistent musty smell coming from his crawl space and discovered early signs of white rot forming on the wooden support beams. After running an Abestorm crawl space ventilation and moisture control system continuously for two days, humidity levels dropped from 85% to 45%, and the odor was dramatically reduced.

Today, he only runs the system a few days each week to help maintain humidity levels below 50% and keep the space dry and protected.

“I used to avoid going into my crawl space. Now it feels clean, dry, and much more comfortable.”

— Mark, Virginia
