Nordic Pure 17x21x1ExactCustomM10+C-6 Merv 10 Plus Carbon Filter

Product Description

The NORDIC PURE 17x21x1ExactCustomM10+C-6 is a custom-cut, pleated MERV 10 plus carbon AC and furnace air filter supplied in a 6-pack. Built from electrostatically charged synthetic media with an integrated carbon layer, it captures over 85% of airborne particles between 3 and 10 microns in size - including lint, household dust, pollen, pet dander, mold spores, and odors - while maintaining low airflow resistance. The actual dimensions are 17 x 21 x 0.75 inches, cut to exact size for a precise fit. HVAC technicians and homeowners install this filter in forced-air heating and cooling systems where a non-standard filter size is required.

This filter is intended for residential and light commercial forced-air HVAC applications where a custom nominal size of 17x21x1 is specified. Because it is manufactured to exact dimensions, it is well suited for systems where standard stock sizes do not seat properly. The reinforced 2-part frame provides structural support during installation and throughout the service life of the filter. Filter service life varies by environment; changing the filter every 30 to 90 days is the general recommendation for maintaining indoor air quality and system efficiency. The carbon layer addresses common household odors in addition to particulate filtration.

Compatibility

Designed as an exact custom-size replacement filter for forced-air AC and furnace systems requiring a nominal 17x21x1 filter slot with an actual dimension of 17 x 21 x 0.75 inches. Measure the existing filter before ordering; this is a custom-made size and is not eligible for returns.

Installation Notes

Installation is performed by a licensed HVAC technician or a knowledgeable end user. Power down or set the thermostat to the off position before replacing the filter. Confirm airflow direction arrows on the filter frame align with the direction of air movement through the system. Because this is a custom-cut filter, verify actual slot dimensions with a tape measure prior to ordering, as the actual size is 17 x 21 x 0.75 inches, not a full 1-inch depth.
