Nordic Pure 20x21x1ExactCustomM8-12 Merv 8 Filter 12 Pack

Product Description

The NORDIC PURE 20x21x1ExactCustomM8-12 is a custom-made, pleated AC furnace air filter rated MERV 8, sized at an exact 20 x 21 x 0.75 inches and sold in a 12-pack. It is designed to capture airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores, with a capture rate of 70 to 85 percent for that size range. The filter media is electrostatically charged and built on a moisture-resistant beverage board frame. This filter is custom-fabricated to the listed exact dimensions and is not returnable. 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 applications where standard nominal sizes do not match the actual filter opening. The exact actual size of 20 x 21 x 0.75 inches makes it appropriate for systems requiring a precise fit rather than a standard nominal-sized filter. It is recommended to replace this filter every one to three months under normal conditions. Households with pets or occupants with allergies may require more frequent replacement. This filter is hand-fabricated to the dimensions specified at the time of order.

Compatibility

Designed as a custom exact-fit replacement for residential and light commercial HVAC systems requiring a filter with an actual size of 20 x 21 x 0.75 inches. Measure the existing filter opening before ordering, as custom sizes are non-returnable.

Installation Notes

HVAC technicians and qualified service professionals should power down the air handling unit before replacing the filter. Confirm the actual dimensions of the filter slot with a tape measure before installation, as nominal and actual sizes frequently differ. Install with the airflow direction arrow on the frame pointing toward the blower. Follow local mechanical codes for filter maintenance intervals in commercial applications.
