Most homeowners rarely, if ever, think about their home’s indoor air quality. But it may be time to start. According to the Environmental Protection Agency (EPA), the air inside the average American household is up to five times more polluted than the air outside. Pollutants commonly found in the home consist of bioaerosols and particles such as dust, pollen, viruses, bacteria and even potentially harmful chemicals or gases. These airborne particles can lead to an increase in allergy and asthma symptoms, sickness or unpleasant odors.
