Indoor Air Quality
 

Poor ventilation and design flaws, such as inappropriate roofing, are primary reasons for the low quality of indoor door air. The improper use of HVAC systems results in the presence of outside air pollutants, radon, and moisture incursion in the indoor air. Besides, various cleaning and disinfecting supplies and aerosol products can contaminate the indoor air with the chemicals present in them.
