Nordic Pure 21_1/2x23x1ExactCustomM7-6 Merv 7 Filter 6pk

Product Description

The NORDIC PURE 21_1/2x23x1ExactCustomM7-6 is a custom-cut pleated AC furnace air filter rated MERV 7, sold in a 6-pack. The actual dimensions are 21.5 x 23 x 0.75 inches. It is designed for residential and light commercial forced-air HVAC systems, including central air conditioners and gas or electric furnaces. The electrostatically charged filter media captures lint, dust, pollen, pet dander, mold spores, and dust mites. The heavy-duty, moisture-resistant beverage board frame provides structural support. Licensed HVAC technicians and knowledgeable homeowners install this filter as a direct drop-in replacement to maintain indoor air quality and protect HVAC equipment.

This filter is suited for residential homes and light commercial spaces using standard 1-inch filter housings. Because it is a custom-made exact-size filter, the nominal size of 21.5 x 23 x 1 inch corresponds to an actual size of 21.5 x 23 x 0.75 inches. It is appropriate for environments with pets, allergy concerns, or elevated dust loads. Replacement every 1 to 3 months is typical, with more frequent changes recommended in high-particulate environments. The filter is manufactured in the USA using a reinforced 2-part frame construction, which may incorporate tape depending on the final cut dimensions.

Compatibility

Installation Notes

Power down the HVAC system at the thermostat or disconnect before removing the existing filter. Confirm the actual slot dimensions with a tape measure before installation, as nominal and actual filter sizes frequently differ. Insert the new filter with the airflow arrow pointing toward the blower. Custom-cut filters are non-returnable; measure carefully before ordering.
