Crawl Space Air Quality & Humidity Control Solutions

Our team at Perma-Seal offers crawl space air quality and humidity control solutions for home and business owners in the Chicago and NW Indiana areas. 

In addition to preventing water from damaging your crawl space, the most important part of crawl space encapsulation is being able to control humidity levels and improve the air quality. A large portion of the air in a home will travel up through the crawl space, therefore it is important that this air is of the highest quality. Healthy air can improve the overall health of people in the home, it will help prevent the growth of mildew and mold in the crawl space.

The EPA states that indoor air pollution is one of the top five environmental health risks. Common sources of indoor air pollution are building materials and furnishings such as insulation, damp carpet, certain types of furniture, household cleaners, humidifiers, and even outdoor air pollution. The installation of a crawl space air filtration and dehumidification system can both reduce the impact of these pollutants as well as help control the overall humidity levels in your home.

How PermaDry Helps Keep Your Crawl Space Dry

Your crawl space is part of your building and if there are high humidity levels and musty odors underneath your home it will affect your main living spaces.

Crawl Space Dehumidifier and Air Filter In One

The PermaDry is the perfect dehumidifier for crawl spaces that experience high levels of relative humidity because it can keep that level below 50%, preventing mold growth. Not only does it remove mold spores, allergens and excess humidity, but it can also purify the air throughout your entire home.

The PermaDry has the addition of a filter system to keep the air clean. This filter removes mold spores, dust mite droppings, captures virus-size airborne particles, dust, and other particulates, and also features a carbon-infused filter that can help eliminate odors.
