Nordic Pure 20x21x1ExactCustomM13-6 Merv 13 Filter 6 Pack

Product Description

The NORDIC PURE 20x21x1ExactCustomM13-6 is a custom-made, pleated AC furnace air filter rated MERV 13, supplied in a pack of six. Each filter measures 20 x 21 x 0.75 inches actual size and is hand-cut to those exact dimensions. The electrostatically charged pleated media captures over 90% of airborne particles between 1 and 10 microns, and 50% to 70% of particles between 0.3 and 1 microns. The heavy-duty, moisture-resistant beverage board frame supports airflow while maintaining filter integrity. Licensed HVAC technicians and qualified service pros install these as direct replacements in residential and light commercial air handling equipment.

These filters are suited for residential forced-air furnaces, central air conditioning systems, and light commercial air handlers where high-efficiency particle capture is required. Typical applications include homes with occupants who have allergy sensitivities, pet dander concerns, or exposure to smoke and smog. Nordic Pure recommends replacing the filter every one to three months under normal conditions, and more frequently in high-use or high-contamination environments. Because this is a custom-cut size, the actual dimensions should be verified against the installation opening before ordering.

Compatibility

Designed as a custom exact-size replacement for residential and light commercial forced-air furnace and AC systems that require a 20 x 21 x 1 nominal filter opening. Verify the actual opening dimensions before ordering, as custom-cut filters are not eligible for return.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified service professional. Power down the air handler or furnace at the disconnect or breaker before removing the existing filter. Note the airflow direction arrow on the filter frame and orient the replacement filter to match before closing the filter door or access panel. Custom-cut filters may incorporate taped seams depending on the final dimensions - inspect the frame for integrity before installation.
