A pleated air filter is made from a sheet of polyester, paper, or cotton folded into pleats to increase the entire surface area. This allows the filter to trap more airborne particles such as dust, dirt, and hair (from pets and humans), which could otherwise damage your furnace's blower fan and clog the AC coils. As a secondary benefit, a pleated filter will improve the indoor air quality of your home.
