Four Seasons™ Filter Media
Utilizing electrostatically charged, 100% synthetic media, our one-year air filters offer significantly higher particulate efficiency than regular poly/cotton media pleated filters, with little change in static pressure. MERV 8 filter media will not promote the growth of bacteria, mold, mildew, or fungi in normal operating environments, and has not been chemically treated. Four Seasons™ MERV 8 pleated filters are an ideal upgrade from standard disposable panel filters. These filters are designed to last up to 12 Months.
