Air filters are the unsung heroes of your home comfort system. They have one of the most important jobs in the system, but they’re often forgotten — to the detriment of your budget. Clogged, dirty air filters cost you money by lowering system performance and driving up utility bills. A dirty filter can shorten the life of your system, too. It’s well worth the small amount of time and effort required to replace the filter monthly, especially in seasons of heavy use — throughout the summer and winter here in the Grand Traverse County area.
Depending upon your system, you may have a pleated or flat panel filter. Pleated filters, because of their greater surface area, are more efficient. Inexpensive flat filters are made of materials such as fiberglass, vegetable fibers, synthetic fibers and more. They may be coated with an oily substance to help them trap particles in the air. Alternatively, filters may be electrostatically charged to attract and remove particles from the air.
Pleated filters make use of similar materials, but with smaller sized fibers packed more densely. Pleats may be stabilized with a wire frame or cardboard separators. Ultra-efficient HEPA filters are made of even smaller, denser material to remove the largest amount of microscopic particles from the air.
Choosing the correct filter is crucial, because a too-dense or ill-fitting filter can decrease your system’s efficiency, causing utility bills to climb as the system works harder to pull air through the filter. Of course this also restricts the fresh air flow in your home and could even cause your system to malfunction. According to the EPA, filters with a MERV efficiency rating from 7 to 13 are nearly as effective as (and much cheaper than) true HEPA filters, which are rated 17 to 20.
