Air Cooling Does Best With Clean Filter

July 16, 1989

Like most people, you probably spend up to 90% of your time indoors.

If you have a central air-conditoning or heating system, you should know that the easiest way to keep your unit running efficiently and your indoor air fresh is to change your air filter regularly.

Dirty filters add up to more money for the consumer because they force the cooling/ heating system to circulate the air while pulling it through a clogged and dirty filter. Most filters can be easily inspected and cleaned or replaced by homeowners.

Consumers have a choice of three types of air filters and electronic air cleaners, according to the Air-Conditioning and Refrigeration Institute.

Standard filters are designed to catch the larger and more visible particles of dust and dirt.

Media filters can remove very small particles that require an optifcal microscope to be seen.

Electronic air filters are the most effcient. They attract and retain pollutants like a powerful magnet.

The latest information about air filters has been summarized in a free pamphet, "Breathing Clean-How Air Filters Provide Cleaner Living." Send a self-addressed, stamped business envelope to: ARI, Department F-13, 1501 Wilson Blvd., 6th Floor, Arlington , Va. 22209
