Description
Panel filters, rated MERV 4, remove large particles from indoor air. A light layer of adhesive on the filter traps dust, dirt, pollen and odors. For stability and sturdiness, the fiberglass media resists compression, includes a double skin and bonds securely to the chipboard frame. When replaced once a month, the filter successfully reduces indoor air pollutants and allows the HVAC system to work efficiently. If the indoor air includes heavy pollutants, replace the filter more frequently.
