Nordic Pure 20x25x1M12-12 Pleated Air Filter Merv 12

Product Description

The NORDIC PURE 20x25x1M12-12 is a pleated MERV 12 air filter sold in a 12-pack, designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioners. The filter media is electrostatically charged and carries an antimicrobial, hypoallergenic treatment that captures lint, household dust, pollen, smoke particles, dust mites, pet dander, mold spores, virus carriers, and other airborne contaminants. At a MERV 12 rating, this filter provides high-efficiency filtration comparable to MPR 1500-1900 on proprietary scales, following the ASHRAE industry standard. The moisture-resistant beverage board frame holds its shape across normal service intervals. Licensed HVAC technicians and knowledgeable facility maintenance staff are the typical installers.

This filter is suited for residential single-family homes, multi-family units, and light commercial office environments where improved indoor air quality is a priority. It is a strong choice for occupants managing moderate allergies, asthma, or pet dander sensitivity. The ASHRAE MERV 12 rating means the media is effective against smaller particulates than MERV 8 or MERV 11 filters while maintaining acceptable airflow in most standard residential air handlers. Filter replacement every one to three months is typical, with shorter intervals recommended in high-traffic, high-dust, or pet-heavy environments. Nominal size is 20x25x1 inches.

Compatibility

Designed as a direct-fit replacement for standard 20x25x1 nominal filter slots in residential and light commercial forced-air furnaces and central air conditioning systems. Actual filter dimensions are 19.5 x 24.5 x 0.75 inches. Always verify the actual slot dimensions before installation, as nominal and actual sizes differ across equipment brands.

Installation Notes

Shut down the HVAC system at the thermostat and, where practical, at the air handler disconnect before removing the old filter. Note the airflow direction arrow printed on the filter frame and orient the replacement so the arrow points toward the blower, not toward the return air duct. Verify the actual slot dimensions with a tape measure before inserting the filter, since nominal sizing varies by manufacturer. HVAC technicians should follow local mechanical codes and the equipment manufacturer's maintenance schedule when specifying filter replacement intervals.
