Nordic Pure 20x20x5HM12-4 Merv 12 Air Filter 4 Pack

Product Description

The NORDIC PURE 20x20x5HM12-4 is a MERV 12 rated pleated air filter designed for high-efficiency residential and light commercial HVAC systems. Sold in a 4-pack, each filter carries a nominal size of 20x20x5 inches with an actual size of 19.63 x 19.88 x 4.38 inches. The filter media is hypoallergenic, antimicrobial, and electrostatic, capturing lint, household dust, pollen, smoke particles, dust mites, pet dander, virus carriers, mold spores, and other airborne contaminants. A heavy-duty, moisture-resistant beverage board frame and a bonded metal mesh support grid keep the pleats rigid under airflow. Licensed HVAC technicians and qualified service professionals are the typical installers.

This filter is suited for residential forced-air furnace and air handler applications where high particulate capture is required, including households with moderate allergy concerns. The MERV 12 rating is comparable to MPR 1500-1900. It serves as a direct replacement for Honeywell 20x20x4 filters and compatible units from Lennox, Carrier, and Bryant that accept a filter with an actual depth of 4.38 inches. Always measure the existing filter or filter housing before ordering, as nominal and actual dimensions vary by manufacturer and housing design, particularly in the 4-inch and 5-inch depth range.

Installation Notes

Filter replacement is typically performed by a licensed HVAC technician or a knowledgeable service professional. Always shut down the furnace or air handler at the thermostat and disconnect power at the disconnect switch or breaker before opening the filter housing. Confirm airflow direction arrows on the filter frame align with system airflow before closing the cabinet. Nordic Pure recommends replacing this filter every 3 to 6 months under normal conditions, with more frequent changes during renovation work or high-dust periods.
