EPA developed construction specifications to help improve indoor air quality in new homes. With design and construction features added to homes build to code, the Indoor airPLUS Construction Specifications help protect qualified homes from moisture and mold, pests, radon, combustion gases, and other indoor air pollutants. Homes that earn the Indoor airPLUS labels are designed to have reduced risk of indoor air quality problems as well as greater comfort and better durability. The construction features of Indoor airPLUS qualified homes can help lead to lower health risks, allergens and asthma triggers.
