Residential According to the EPA the average American spends 70-90% of their time indoors. The EPA also has said that indoor air can be more seriously polluted than outdoor air in major cities. This is largely caused by building tighter homes than we used to have, as well as a change in lifestyle to more luxuries that cause pollution. These pollutants are basically particles and chemical vapors & fumes or gases. The particle contaminants might be mold, mildew, dust, dustmite feces, bacteria, viruses, dander, pollen, etc. Gaseous contaminants are chemicals, cleaning fluids, pesticides, off gassing from household items, personal care products etc. Each pollutant has a different solution and there is no single "cure all" for I.A.Q. problems. New technology has produced many new products to relieve IAQ problems. There are also many "too good to be true" gimmicks on the market, so beware!
