Nordic Pure 16x25x4M7-6 Merv 7 Pleated Air Filter 6 Pack

Product Description

The NORDIC PURE 16x25x4M7-6 is a MERV 7 pleated air filter sold in a six-pack for residential HVAC systems. Each filter uses electrostatically charged, hypoallergenic synthetic media to capture airborne particles in the 3.0 to 10.0 micron range, including household dust, pollen, mold spores, pet dander, and bacteria. The actual size is 15.5 x 24.5 x 3.63 inches, which fits nominal 16x25x4 filter slots. A heavy-duty, moisture-resistant beverage board frame and bonded metal mesh support grid keep the pleats stable under normal airflow conditions. MERV 7 performance is equivalent to MPR 600.

This filter is intended for residential and light-commercial forced-air systems using a nominal 16x25x4 filter slot. It is appropriate for gas furnaces, heat pumps, and central air conditioning systems. HVAC technicians and homeowners typically install this filter at the return-air grille or inside the air handler cabinet. Nordic Pure recommends replacing the filter every 3 to 6 months under normal conditions, and more frequently during renovation or high-dust periods. Note: if the existing filter in the system has an actual depth of 4.375 inches, such as certain Honeywell or Lennox units, the 16x25x5 variant is the correct replacement.

Compatibility

Designed as a direct replacement for nominal 16x25x4 residential HVAC filter slots with an actual depth of 3.63 inches. Not compatible with systems requiring a 4.375-inch actual depth filter, such as certain Honeywell or Lennox units that use a 16x25x5 replacement instead.

Installation Notes

Installation is typically performed by a licensed HVAC technician or a knowledgeable homeowner. Set the system thermostat to the off position before removing the old filter to prevent unfiltered air from circulating through the air handler. Confirm the actual slot dimensions before installing, as nominal and actual filter sizes differ. Dispose of the used filter promptly to avoid redistributing captured particulates.
