Nordic Pure 17x21x1ExactCustomM14-12 Merv 14 Filter 12 Pack

Product Description

The NORDIC PURE 17x21x1ExactCustomM14-12 is a custom-cut, pleated AC furnace air filter rated MERV 14, manufactured to exact dimensions of 17 x 21 x 0.75 inches. Sold in a 12-pack, this filter is designed for HVAC professionals and facilities managers who need precise sizing that standard off-the-shelf filters cannot provide. The electrostatic pleated media captures over 90% of airborne particles between 1 and 10 microns, and 75% to 95% of particles between 0.3 and 1 micron, including bacteria, mold spores, smoke, and virus carriers. The heavy-duty, moisture-resistant beverage board frame supports consistent airflow and structural integrity throughout the filter life.

This filter is suited for residential and light commercial HVAC systems requiring high-efficiency filtration. MERV 14 performance is comparable to MPR 2800-rated filters. Because MERV 14 restricts airflow more than lower-rated filters, the HVAC system must be rated to handle MERV 14 or higher before installation. This rating makes the filter well-suited for newer high-efficiency systems, environments with allergy or asthma concerns, and spaces where airborne pathogen reduction is a priority. Nordic Pure recommends replacing filters every 1 to 3 months, with more frequent changes in homes with pets or occupants sensitive to allergens. The 12-pack format supports a consistent replacement schedule.

Compatibility

Designed as a custom exact-size replacement filter for residential and light commercial HVAC, furnace, and air conditioning systems with a 17 x 21 x 1 nominal filter opening. The HVAC system must be rated to operate with MERV 14 or higher filters. Verify actual filter slot dimensions before ordering, as custom sizes are non-returnable.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Power down or set the thermostat to the off position before removing the existing filter to prevent unfiltered air from circulating through the air handler. Confirm the airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower before seating the filter. Because this is a custom-cut size, measure the actual filter slot opening carefully before ordering, as these filters are hand-made to specified dimensions and are not eligible for return.
