What You Need to Know About Indoor Air Quality08/08/2016 The majority of people realize how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual house can be more polluted—contingent on actual circumstances, it can be up to five times more. Things have become so dangerous, the EPA has indoor air pollution classified as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found indoors.

This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are destroyed.
