Pleated Air Filter: 18 x 20 x 2", MERV 8, 35% Efficiency, Wire-Backed Pleated MPN:PRO32035

This pleated air filter is designed to provide superior indoor air quality for residential or light commercial use by trapping up to 85% of all allergens and particles down to 1 micron in size, including pollen, dust mites, and smoke. Featuring a MERV rating of 8 with an efficiency of 35%, this filter offers medium efficiency for most air cleaning applications. It is constructed using wire-backed pleated media that helps support its shape, resist collapse under pressure, and provide extended durability while remaining reusable for several months before needing replacement. Ideal for use within HVAC systems as a pre-filter to enhance the performance of heavier duty filters or standalone to protect your furniture and walls from dust accumulation when fresh air is brought into the room.
