Nordic Pure 19x25x1CustomM12-6 Merv 12 Furnace Filter 6 Pack

Product Description

The NORDIC PURE 19x25x1CustomM12-6 is a custom-made MERV 12 pleated air filter designed for residential and light commercial HVAC systems, including forced-air furnaces and central air conditioners. Sold in a 6-pack, each filter measures an actual 18.5 x 24.5 x 0.75 inches with a nominal size of 19 x 25 x 1 inches. The electrostatically charged pleated media captures over 90% of airborne particles between 3 and 10 microns, and 80% to 90% of particles between 1 and 3 microns. The heavy-duty, moisture-resistant beverage board frame provides structural integrity, while the media is engineered to resist bacterial and mold growth on the filter surface. Licensed HVAC technicians and knowledgeable homeowners install these filters as part of routine system maintenance.

This filter is suited for residential homes and commercial office environments where occupants require above-average particulate control. MERV 12 performance is comparable to MPR 1500 to 1900 rated filters from other manufacturers. This rating follows the ASHRAE filtration standard, which measures efficiency across particle size ranges. Target contaminants include lint, dust, pollen, pet dander, mold spores, smoke particles, bacteria, virus carriers, and general allergens. Replacement is recommended every 1 to 3 months, with more frequent changes advised in homes with pets or allergy sufferers. This is a custom-cut size, hand-fabricated to the exact nominal dimensions specified, and is not eligible for return.

Compatibility

Designed as a custom OEM-style replacement filter for residential and light commercial forced-air furnaces and central air conditioning systems that accept a nominal 19 x 25 x 1 inch filter. Verify the actual filter slot dimensions against the actual size of 18.5 x 24.5 x 0.75 inches before ordering, as this is a non-returnable custom size.

Installation Notes

Filter replacement is typically performed by an HVAC technician or a qualified building maintenance professional, though homeowners frequently handle routine changeouts. Always shut down the HVAC system at the thermostat or disconnect before removing the existing filter to prevent unfiltered air from circulating through the equipment. Note the airflow direction arrow on the filter frame and orient the replacement filter accordingly. Because this is a custom-fabricated size, measure the existing filter slot carefully before ordering, as returns are not accepted on custom dimensions.
