There Are Always Pollutants

But you don't smoke, don't have pets, and a nice, lush lawn keeps the dust outside where it belongs. So you assume, and logically so, that you don't need a HEPA air purifier. This is, unfortunately, not the case. You would be shocked at what all can contaminate your home. Do you, by chance, have furniture? The dyes in fabrics and the chemicals used to treat the wood frames are all susceptible to what's called outgassing. The outgassing of these chemicals pollutes your air. That wonderful green lawn that keeps the dust down? Pollen, natural as it may be, is just as much a pollutant as anything manufactured. HEPA air purifiers are made to take care of just about every contaminant out there.
