As more homeowners have recognized the need to properly seal their home to improve energy efficiency, the resulting effect has been a dramatic reduction of indoor air quality. Replacing the heating and cooling system of your home can be very costly, but there are ways to help improve the indoor air quality without going to such expense.
For existing systems, your best bet is to replace the air filters with a two or even three-stage filter. With these new filters, it is now possible to control harmful airborne microorganisms, gasses and even dust particles.
While not readily available at all hardware stores, many of these filters can be purchased online. Be sure to look for high density carbon or polycarbon in the item’s description. You can also improve the quality of air in your home by using these filters in conjunction with a stand alone room ionizer.
