Nordic Pure 20x25x1M10-4 Pleated Air Filter Merv 10

Product Description

The NORDIC PURE 20x25x1M10-4 is a MERV 10 pleated air filter sold in a 4-pack, designed for residential and light commercial HVAC systems including furnaces and central air conditioners. The filter media is electrostatically charged and carries an antimicrobial, hypoallergenic treatment to capture airborne particulates and resist microbial growth on the media surface. The beverage board frame is moisture resistant and holds its shape under normal system airflow. At MERV 10, this filter is equivalent to MPR 1000 and captures particles including pollen, pet dander, dust mites, mold spores, smoke particles, bacteria, and virus carriers, making it a practical upgrade over standard fiberglass filters.

This filter is suited for residential furnaces and central air conditioning systems where improved indoor air quality is a priority. It is a strong fit for households with pets or occupants with mild allergies. The nominal size is 20x25x1, with an actual size of 19.5 x 24.5 x 0.75 inches. Manufacturers and ASHRAE recommend replacing MERV 10 filters every one to three months under normal conditions, and more frequently in high-dust or high-dander environments. Because nominal and actual filter dimensions differ, always verify the actual slot dimensions before ordering.
