MERV RATING: 11 Specifically Designed to Replace : Aprilaire/Space-Gard 2200 and 2250, Carrier 31MF and General AC-1 Media Replacements. 53 times more effective than fiberglass filters and will last up to 1 year. Tear Resistant Filter Material-True Blue's Polypropylene Proprietary Filter Media is produced to our exacting specifications using the finest grade synthetic fibers to ensure no tearing of filter during installation or normal use (unlike alternatives made from fiberglass). Installs In Minutes - The attached string makes installing pleat spacers easy and trouble free. Electrostatically Charged filter media filters sub-micron airborne allergens like dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke and smog. 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.
