Studies from the Environmental Protection Agency on human exposure to air pollutants show that indoor levels of pollutants may be two to five times higher than outdoor levels. Residential ventilation was not a problem in the past since homeowners were getting enough outdoor air by opening windows and by fresh air leaking through walls, but now that homes are built tighter to save energy, contaminants and pollutants can get trapped inside. Considering that we spend about 90% of our days indoors, that means we’re breathing polluted air the majority of the time.
The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) created a list of recommendations that homeowners can follow to help them and their families breathe cleaner air. Suggestions include where to have air conditioning and furnace units installed, venting restrooms and laundry rooms directly outdoors, and using a good air filter to keep dirt and dust out of your ductwork.
Keep this list on hand to ensure cleaner air in your home, and if you have any questions about air filters, proper ventilation or any other indoor air quality questions, give One Hour Heating & Air Conditioning® of Aberdeen a call.
