MERV 7 pleated air filters utilize electro statically charged, 100% synthetic media which offers significantly higher particulate efficiency than regular poly/cotton media pleated filters, with little change in static pressure. MERV 7 filter media will not promote the growth of bacteria, mold, mildew, or fungi in normal operating environments, and has not been chemically treated. Using these well rated filters and combined with preventative maintenance  , Sub-Zero tries to preserve the life of your equipment  through these action.
