Nordic Pure 17x21x1ExactCustomM10-6 Merv 10 Filter 6 Pack

Product Description

The NORDIC PURE 17x21x1ExactCustomM10-6 is a custom-cut, pleated AC furnace air filter rated MERV 10 and sold in a 6-pack. It is designed for residential and light commercial HVAC systems where improved indoor air quality is a priority. The filter media is electrostatically charged to attract and hold airborne particles, and the frame is constructed from a moisture-resistant beverage board. At MERV 10, it captures more than 85 percent of airborne particles in the 3-10 micron range, including lint, dust, pollen, pet dander, and mold spores. Licensed HVAC technicians and knowledgeable homeowners typically install and replace this filter as part of routine system maintenance.

This filter is sized to an actual dimension of 17 x 21 x 0.75 inches, making it a custom exact-fit unit rather than a standard nominal-size filter. It is suited for forced-air gas furnaces, heat pumps, and central air conditioning systems where the filter slot requires a precise fit. Because the filter is custom-made to exact dimensions, it is manufactured by cutting down or combining standard filter frames, which may include taped seams. The MERV 10 rating is comparable to MPR 900-1000 ratings used by other manufacturers, all benchmarked against the same ASHRAE efficiency criteria. This pack of six supports a regular 1-to-3-month replacement schedule for most households.

Compatibility

Designed as a custom exact-fit replacement filter for residential and light commercial HVAC systems requiring a 17 x 21 x 0.75 inch actual-size air filter. Verify the exact opening dimensions of the filter slot before ordering, as this is a non-returnable custom-made product.

Installation Notes

Filter replacement is a standard HVAC maintenance task performed by licensed technicians or qualified homeowners. Power down the air handler or furnace at the disconnect or thermostat before removing the old filter. Confirm airflow direction marked on the filter frame matches the direction of air movement into the blower. Because this is a custom-cut filter, measure the actual filter slot dimensions carefully prior to ordering, as custom sizes cannot be returned or exchanged.
