What You Need to Know About Indoor Air Quality08/08/2016 The majority of people are aware of how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average house often is more polluted—contingent on actual circumstances, it can be up to five times more. Things have become so bad, the EPA has indoor air pollution ranked 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 captured.
