Nordic Pure 21x22x1ExactCustomM8-6 Merv 8 Furnace Filter 6 Pack

Product Description

The NORDIC PURE 21x22x1ExactCustomM8-6 is a custom-cut, pleated AC furnace air filter rated MERV 8, supplied in a 6-pack. Manufactured to exact dimensions of 21 x 22 x 0.75 inches, this filter fits applications where standard nominal sizes fall short. The electrostatically charged filter media captures lint, dust, pollen, pet dander, mold spores, and other common airborne particles in the 3-10 micron range at a 70-85 percent capture rate. The heavy-duty, moisture-resistant beverage board frame provides structural support throughout the filter life. Licensed HVAC technicians and service professionals install these filters in residential and light commercial air handling systems.

This filter is suited for residential and commercial HVAC systems where an exact 21 x 22 x 0.75 inch fit is required. Custom sizing makes it appropriate for non-standard filter cavities in forced-air furnaces, air handlers, and central AC systems. The MERV 8 rating is comparable to MPR 800-rated filters and aligns with ASHRAE filtration standards. Recommended replacement interval is every 1 to 3 months, though households with pets or allergy sensitivities may require more frequent changes. The custom construction may incorporate tape or combined frames depending on the final dimensions.

Compatibility

Designed as a custom OEM-style replacement filter for residential and light commercial forced-air furnaces and air handlers requiring an exact 21 x 22 x 0.75 inch filter. Measure the existing filter cavity before ordering, as this is a custom size and actual dimensions differ from nominal sizing printed on standard filters.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified service professionals. Power down the furnace or air handler at the disconnect or thermostat before removing or installing the filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Because this is a custom-made product, verify exact cavity measurements prior to ordering, as custom filters are non-returnable.
