The NORDIC PURE 21x22x1ExactCustomM12-6 is a custom-cut, pleated AC furnace air filter rated MERV 12, sized to an actual dimension of 21 x 22 x 0.75 inches and sold in a 6-pack. It is designed for residential and light commercial HVAC systems where higher-efficiency filtration is required without sacrificing airflow. The electrostatically charged filter media captures over 90% of airborne particles between 3 and 10 microns and 80% to 90% of particles between 1 and 3 microns. A moisture-resistant beverage board frame provides structural integrity, and the media is manufactured to resist bacterial and mold growth on the filter surface itself. Licensed HVAC technicians and knowledgeable installers are the primary users of this filter.
This filter is suited for residential forced-air furnaces, central air conditioning systems, and light commercial air handlers where indoor air quality is a priority. Common applications include households with pets, allergy sufferers, and environments with elevated dust or particulate loads. MERV 12 efficiency is comparable to filters rated MPR 1500-1900 on proprietary scales used by some manufacturers. Nordic Pure rates filtration performance according to the ASHRAE MERV standard. Because this is a custom-made size, it is built to the exact dimensions entered at the time of order by cutting down or combining standard filter frames, and may incorporate tape reinforcement depending on the final dimensions.
Designed as an OEM-style replacement filter for residential and light commercial forced-air furnaces, central AC systems, and air handlers that accept a filter with an actual opening size of 21 x 22 x 0.75 inches. Verify the actual opening measurement before ordering, as this is a custom, non-returnable size.
Filter installation and replacement is typically performed by licensed HVAC technicians or qualified service personnel. Always shut down the air handler or furnace at the equipment disconnect or thermostat before removing or inserting a filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow in the system before securing the filter door. Nordic Pure recommends replacing this filter every 1 to 3 months depending on occupancy, pet presence, and local air quality conditions.
