Nordic Pure 17x21x1ExactCustomM12-6 Merv 12 Filter 6 Pack

Product Description

The NORDIC PURE 17x21x1ExactCustomM12-6 is a custom-cut MERV 12 pleated air filter designed for residential and light commercial HVAC systems, including central air conditioners and gas or electric furnaces. Rated MERV 12, it captures over 90% of airborne particles between 3 and 10 microns and 80% to 90% of particles between 1 and 3 microns. The electrostatically charged filter media attracts lint, dust, pollen, pet dander, mold spores, smoke, bacteria, and virus carriers. Each filter ships in a 6-pack. The nominal size is 17x21x1 with an actual size of 17 x 21 x 0.75 inches. A licensed HVAC technician or knowledgeable installer can fit this unit into standard filter slot applications.

This filter is suited for residential homes and commercial spaces where higher-efficiency filtration is needed without excessive static pressure loss. It is a direct fit for air handlers, furnaces, and return-air grilles sized for a 17x21x1 nominal slot. Nordic Pure constructs custom sizes by cutting down or combining standard filter frames, using tape where necessary to achieve the specified dimensions. Replacement every 1 to 3 months is typical, though households with pets or allergy sensitivities may require more frequent changes. The MERV 12 efficiency rating is equivalent to MPR 1500 to 1900 on competing scales and conforms to ASHRAE filtration standards.

Compatibility

Designed as a custom-fit replacement for residential and commercial HVAC systems with a 17x21x1 nominal filter slot. Verify the exact opening dimensions before ordering, as this is a non-returnable custom-made product. Actual installed size is 17 x 21 x 0.75 inches.

Installation Notes

HVAC technicians and qualified installers should power down the air handler or furnace at the disconnect or breaker before servicing the filter compartment. Confirm airflow direction marked on the filter frame aligns with the system airflow arrow before inserting. Because this is a custom-cut size, measure the actual filter slot opening to the nearest fraction of an inch before ordering to ensure proper fit. Follow local mechanical codes and the equipment manufacturer guidelines for filter replacement intervals.
