The NORDIC PURE 13x21_1/2x1CustomM8-6 is a custom-cut, MERV 8 rated pleated air filter designed for residential and light commercial HVAC systems. Sold in a 6-pack, each filter measures 12.75 x 21.5 x 0.75 inches actual size and is built with a moisture-resistant beverage board frame. The electrostatically charged filter media captures lint, dust, pollen, pet dander, mold spores, and dust mites, removing them from the airstream with each pass. MERV 8 efficiency is equivalent to an MPR 800 rating and is rated per ASHRAE standards. Licensed HVAC technicians and knowledgeable homeowners install this filter as a direct replacement in forced-air furnace and air handler systems.
This filter is suited for residential homes, apartments, and light commercial spaces where improved indoor air quality is a priority. It is particularly well-suited for households with pets or allergy sufferers, where higher filtration frequency is recommended. Because this is a custom-fabricated size, it is made to the exact nominal dimensions of 13 x 21.5 x 1 inches to fit non-standard filter slots. Nordic Pure recommends replacing the filter every 1 to 3 months depending on usage conditions and air quality demands. Homes undergoing renovations or with active pets may require more frequent changes.
Designed as a custom OEM-style replacement filter for residential and light commercial forced-air furnaces, air handlers, and central AC systems that accept a filter slot accommodating nominal 13 x 21.5 x 1 inch dimensions. Measure the actual opening in your unit before ordering, as this is a non-returnable custom size.
Filter installation is performed by HVAC technicians or the system owner. Always power down the furnace or air handler at the disconnect or thermostat before removing the existing filter. Confirm airflow direction before inserting the new filter - most filter frames include an arrow indicating proper orientation toward the blower. Because this is a custom-cut size, verify the actual slot dimensions against the filter actual size (12.75 x 21.5 x 0.75 inches) before installation to ensure a proper fit with minimal bypass.
