Nordic Pure 18x24x4M10-1 Pleated Air Filter Merv 10

Product Description

The NORDIC PURE 18x24x4M10-1 is a MERV 10 pleated air filter designed for residential and light-commercial HVAC systems, including forced-air furnaces and central air conditioners. It uses electrostatically charged synthetic filter media to capture airborne particulates on each pass through the system. The nominal size is 18x24x4 inches with an actual size of 17.5 x 23.38 x 3.63 inches. The filter captures more than 85% of 3.0-10.0 micron contaminants and up to 65% of 1.0-3.0 micron contaminants. A heavy-duty, moisture-resistant beverage board frame and a bonded metal mesh support grid maintain filter integrity under normal airflow conditions.

This filter is suited for residential homes and light-commercial spaces where improved indoor air quality is a priority. It is appropriate for systems requiring a standard 18x24x4 filter slot. Targeted contaminants include lint, household dust, pollen, dust mites, pet dander, bacteria, mold spores, smoke particles, virus carriers, and other common airborne pollutants. The MERV 10 rating is equivalent to MPR 1000. Replacement is recommended every 3-6 months, though heavily occupied spaces or homes undergoing renovation may require more frequent changes.

Compatibility

Designed as a direct replacement for standard 18x24x4 nominal filter slots in residential and light-commercial forced-air furnaces and central air conditioning systems. Actual installed dimensions are 17.5 x 23.38 x 3.63 inches. Measure the existing filter slot before ordering to confirm fit.

Installation Notes

Air filters in forced-air HVAC systems are typically replaced by HVAC technicians or qualified service professionals, though many homeowners handle routine filter changes. Before replacing the filter, set the thermostat to off to prevent the blower from drawing air through an open filter slot. Note the airflow direction arrow printed on the filter frame and orient it so air flows through the filter toward the blower. Confirm actual slot dimensions against the filter actual size of 17.5 x 23.38 x 3.63 inches before installation.
