The NORDIC PURE 16x25x4M10-2 is a MERV 10 pleated air filter sold in a 2-pack, designed for residential and light-commercial forced-air heating and cooling systems. The filter media is electrostatically charged synthetic material that captures airborne particulates on each pass through the system. It removes more than 85% of 3.0-10.0 micron contaminants and up to 65% of 1.0-3.0 micron contaminants. The nominal size is 16x25x4 with an actual size of 15.5 x 24.5 x 3.63 inches. The heavy-duty beverage board frame is moisture resistant, and a metal mesh support grid is bonded to the pleats for structural integrity. Licensed HVAC technicians and knowledgeable homeowners install this filter as a routine maintenance item.
This filter is suited for residential gas furnaces, air handlers, and central air conditioning systems that use a 16x25x4 nominal filter slot. It is particularly appropriate in homes with pets, allergy sufferers, or occupants sensitive to airborne particulates including pollen, pet dander, mold spores, smoke particles, bacteria, virus carriers, and dust mites. NORDIC PURE MERV 10 performance is equivalent to an MPR 1000 rating. Note: the actual depth of this filter is 3.63 inches. If your existing filter has an actual depth of 4 3/8 inches, such as certain Honeywell or Lennox units, the 16x25x5 variant is the correct replacement.
Designed as a direct-fit replacement for residential and light-commercial forced-air systems using a 16x25x4 nominal filter slot with an actual depth of approximately 3.63 inches. Not a direct replacement for units requiring a filter with a 4 3/8 inch actual depth, such as certain Honeywell or Lennox 16x25x4 applications - those require the 16x25x5 variant.
Power down the air handler or furnace at the disconnect or thermostat before removing the old filter. Confirm the actual slot dimensions against the filter actual size of 15.5 x 24.5 x 3.63 inches before installation. Install with the airflow arrow on the frame pointing toward the blower. NORDIC PURE recommends replacing this filter every 3 to 6 months, though higher-dust environments or ongoing home renovation may require more frequent changes.
