Nordic Pure 20x25x4M7-2 Pleated Merv 7 Air Filter 2 Pack

Product Description

The NORDIC PURE 20x25x4M7-2 is a two-pack of pleated MERV 7 residential air filters designed for forced-air heating and cooling systems. Each filter uses electrostatically charged, hypoallergenic synthetic media to capture airborne particulates including household dust, lint, pollen, dust mites, pet dander, mold spores, and bacteria. The heavy-duty beverage board frame is moisture resistant, and a bonded metal mesh support grid reinforces the pleated media under airflow load. The filter media also carries antimicrobial properties that inhibit the growth of bacteria and mold within the filter itself. These filters are manufactured in the USA.

The 20x25x4M7-2 is suited for residential and light-commercial forced-air systems using a nominal 20x25x4 filter slot. The actual size is 19.5 x 24.5 x 3.625 inches, which is standard for most OEM 20x25x4 filter housings. Note: if the existing filter in your system has an actual depth of 4.375 inches, such as certain Honeywell or Lennox units, this filter is not the correct fit. Those applications require the 20x25x5 replacement with a 4.375-inch actual depth. Licensed HVAC technicians and knowledgeable homeowners install this filter during routine maintenance cycles.

Compatibility

Designed for residential and light-commercial forced-air HVAC systems with a nominal 20x25x4 filter slot and an actual filter opening that accepts a 19.5 x 24.5 x 3.625-inch filter. Not compatible with housings requiring a 4.375-inch actual depth, such as certain Honeywell and Lennox 20x25x4 units; those applications require the 20x25x5 (4.375-inch actual depth) variant.

Installation Notes

This filter is installed by HVAC technicians or qualified homeowners during scheduled filter maintenance. Always shut down the air handler or furnace at the thermostat and disconnect power at the disconnect switch or breaker before opening the filter access panel. Confirm the actual filter cavity dimensions before installation, as nominal and actual sizes differ across manufacturers. Replace every 3 to 6 months under normal operating conditions, or more frequently during home renovation activity or high-dust periods.
