Why You Need to Change Your Furnace Filter

According to the Environmental Protective Agency (EPA), indoor air is much more polluted than outdoor air. To reduce indoor air pollution and to improve air quality in the home, especially for children and those with allergies, a good air filter for your heating and air conditioning system is a necessity. In addition to health considerations, keeping your heating and cooling system properly filtered ensures that it works efficiently. An efficient system means lower energy costs, fewer repair bills, and a longer life for your heating and air conditioning system.

The filter for a heating and air conditioning system should be examined every month and changed every one to six months. The length of time you can go without replacing your air filter depends on several things, including the quality of the filter you use, the time of year, whether the system is in continuous operation, and where you live. For instance, very efficient filters that trap a great deal of dust must be cleaned or changed much more frequently than cheaper filters that may not do such a good job of catching dust.
