Nordic Pure 25x25x1M10-4 Merv 10 Air Filter 4 Pack

Product Description

The NORDIC PURE 25x25x1M10-4 is a pleated MERV 10 air filter sold in a 4-pack, designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioning units. The nominal size is 25x25x1 inches with an actual size of 24.5 x 24.5 x 0.75 inches. Rated MERV 10 per ASHRAE standards - equivalent to MPR 1000 - this filter captures pollen, dust, pet dander, smoke particles, mold spores, bacteria, virus carriers, and other airborne contaminants. The electrostatically charged, hypoallergenic media will not promote bacterial or mold growth on the filter surface. The frame is constructed from moisture-resistant beverage board for structural integrity during the full service life.

This filter is suited for residential homes and light commercial spaces where occupants require mid-range particulate filtration, particularly those managing mild allergies or pet dander. It installs in standard 1-inch filter slots in gas furnaces, heat pumps, and split-system air handlers. Replacement is recommended every 1 to 3 months, with more frequent changes advised in homes with pets, high dust loads, or allergy-sensitive occupants. Regularly replacing the filter maintains system airflow and helps the HVAC unit operate efficiently.

Compatibility

Designed as a direct replacement for any residential or light commercial forced-air system requiring a nominal 25x25x1 inch filter. Always verify the actual slot dimensions against the actual filter size of 24.5 x 24.5 x 0.75 inches before installation, as nominal and actual sizes differ.

Installation Notes

Installation is performed by HVAC technicians or knowledgeable homeowners as part of routine preventive maintenance. Power down the air handler or furnace before opening the filter compartment and replacing the filter. Confirm airflow direction by matching the arrow printed on the filter frame to the direction of airflow toward the blower. Follow local ASHRAE and HVAC equipment guidelines for recommended replacement intervals.
