Nordic Pure 18x25x1M12-4 Pleated Merv 12 Air Filter 4 Pack

Product Description

The NORDIC PURE 18x25x1M12-4 is a four-pack of pleated MERV 12 air filters sized 17.5 x 24.5 x 0.75 inches actual dimensions. Designed for forced-air HVAC systems in residential and light commercial applications, each filter uses electrostatically charged, hypoallergenic, antimicrobial media to capture lint, household dust, pollen, smoke particles, dust mites, pet dander, virus carriers, mold spores, bacteria, and other airborne contaminants. The heavy-duty moisture-resistant beverage board frame holds its shape under continuous airflow. At MERV 12, these filters deliver high-efficiency filtration equivalent to MPR 1500-1900 ratings used by other manufacturers, all rated under ASHRAE standards.

These filters are suited for residential furnaces, central air conditioning systems, and light commercial air handlers where indoor air quality is a priority. They are especially appropriate in households with pets, allergy sufferers, or occupants with asthma. The MERV 12 rating makes them effective in environments that require a step up from standard MERV 8 filters without the static pressure restrictions of higher-rated MERV 13 or 16 media. Nominal size is 18x25x1; confirm the actual filter slot dimensions before ordering, as the true size is 17.5 x 24.5 x 0.75 inches.

Compatibility

Designed as a replacement for nominal 18x25x1 filter slots in residential and light commercial furnaces, air handlers, and central AC systems. Verify the actual opening size against the stated actual dimensions of 17.5 x 24.5 x 0.75 inches before installation, as nominal and actual sizes differ across equipment brands.

Installation Notes

HVAC technicians and qualified DIYers should power down the air handler or furnace at the thermostat and disconnect power at the breaker before servicing the filter compartment. Confirm airflow direction by matching the arrow printed on the filter frame to the direction of airflow into the blower. Nordic Pure recommends replacement every one to three months under normal conditions; households with pets or allergy concerns should inspect and replace more frequently. Dispose of used filters in a sealed bag to contain captured particulates.
