Nordic Pure 19.875x21.5x1CM12-3 Merv 12 Air Filter 3 Pack

Product Description

The NORDIC PURE 19.875x21.5x1CM12-3 is a MERV 12 pleated air filter designed as a Carrier-compatible replacement for residential and light commercial HVAC systems. Sold in a 3-pack, each filter measures 19.875 x 21.5 x 0.75 inches actual size. The electrostatically charged, hypoallergenic filter media captures lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, and other airborne contaminants. MERV 12 performance is equivalent to MPR 1500-1900 on competing rating scales. The moisture-resistant beverage board frame maintains structural integrity in typical HVAC airstream conditions. Licensed HVAC technicians and knowledgeable homeowners install this filter.

This filter is suited for forced-air furnaces and central air conditioning systems requiring a nominal 19.875 x 21.5 x 1 filter slot. It is well matched for households where occupants have moderate allergies or asthma, and for environments with pets or elevated dust loads. The ASHRAE MERV rating standard governs the efficiency classification, making performance directly comparable across brands regardless of proprietary rating names such as MPR. The filter media does not promote bacterial or mold growth on the filter surface itself, supporting better indoor air quality between change intervals.

Installation Notes

Turn off the furnace or air handler at the thermostat and disconnect power at the disconnect switch or breaker before removing the old filter. Note the airflow direction arrow on the filter frame and install the new filter with the arrow pointing toward the blower. Nordic Pure recommends replacing the filter every 1 to 3 months, with more frequent changes in homes with pets or allergy sufferers. Dispose of the used filter in a sealed bag to contain trapped particulates.
