True Blue Replacement Air Filter for Aprilaire 2200 Series Air Cleaner,MERV 13;

This replacement air filter is specifically designed to fit the Space-Guard models 2200 and 2250. It is 53 times more effective than fiberglass filters and will last up to 1 year. The filters are assembled with a heavy duty frame that prevents collapsing of the filter during installation. During the manufacturing process, we charge the filter media with an electric current. This process allows the filter to attract very small particles much the same way magnets attract metal. The end result is a far more effective filter. The electrostatically charged filter media filters sub-micron airborne allergens like dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke and smog. The 100% synthetic filter media will not support the growth of bacteria, mold, or fungi in normal use.
