Nordic Pure 18x18x1M12-3 Pleated Air Filter Merv 12

Product Description

The NORDIC PURE 18x18x1M12-3 is a three-pack of MERV 12 pleated air filters designed for residential and light commercial HVAC systems, including forced-air furnaces and central air conditioning units. Each filter measures 17.75 x 17.75 x 0.75 inches actual size with a nominal size of 18x18x1 inches. The electrostatically charged, hypoallergenic filter media captures lint, household dust, pollen, smoke particles, dust mites, pet dander, mold spores, virus carriers, and other airborne contaminants. The moisture-resistant beverage board frame holds its shape under normal HVAC airflow conditions. These filters are rated MERV 12 per ASHRAE standards and are manufactured in the USA.

The 18x18x1M12-3 is suited for residential homes, apartments, and light commercial spaces where occupants have moderate allergies, asthma, or pets. The MERV 12 rating makes these filters appropriate for high-efficiency filtration applications where a fiberglass or low-MERV filter is insufficient. They are compatible with standard 1-inch filter slots in forced-air furnace systems and central AC air handlers. Replacement interval is typically every one to three months, though households with pets or allergy sufferers may require more frequent changes. The three-pack format supports scheduled maintenance cycles.

Installation Notes

Filter installation and replacement on residential HVAC equipment is typically performed by HVAC technicians or knowledgeable end users. Before replacing the filter, set the thermostat to off and confirm airflow has stopped. Insert the filter with the airflow arrow on the frame pointing toward the blower, not toward the return air side. Dispose of used filters promptly to avoid redistributing captured particulates.
