Is the air inside my home polluted? Yes, the air we breathe in our homes could be up to 100 times more polluted than outside air. Indoor air pollutants include pollen, dust, pet hair, dander, dust mites, mold spores, bacteria, and virus. Indoor air quality is one of the top five environmental risks to public health today according to the U.S. Environmental Protection Agency (EPA). A standard 1” disposable furnace filter traps only 5% – 15% of airborne particulates. Whole Home Air Cleaners successfully remove up to 99% of small, allergy-causing particulates, giving you the ability to “breathe easy.” Count on Dependable Heating and Cooling and Aprilaire to help make your home environment healthier and cleaner.
