The NORDIC PURE 18x25x1M11MiniPleat-12 is a MERV 11 mini pleat air filter sold in a 12-pack, designed for residential and light commercial HVAC systems. Each filter carries a nominal size of 18x25x1 and an actual size of 17.5 x 24.5 x 0.75 inches, so it seats correctly without gaps or bypass leakage. The mini pleat design packs 2.5 times more pleats than a standard 1-inch filter, delivering more surface area for particle capture while keeping static pressure drop low. The filter media is self-supporting synthetic polyester fiber housed in a moisture-resistant two-part beverage board frame built to hold its shape through the full service interval.
This filter is suited for residential forced-air furnaces and central AC systems as well as light commercial air handlers where a 18x25x1 nominal slot is specified. It targets common airborne contaminants including lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, and allergens. The 12-pack quantity supports a full year of quarterly replacements or longer coverage when multiple filter locations are serviced. Nordic Pure recommends a 2-to-3-month replacement interval, adjusted for renovation activity, pet load, or high-dust environments.
Designed as an OEM-style replacement for any residential or light commercial forced-air system specifying a nominal 18x25x1 filter slot. Always verify the actual filter cavity dimensions against the actual size of 17.5 x 24.5 x 0.75 inches before installation, as nominal and actual sizes differ across HVAC equipment manufacturers.
Filter installation is performed by HVAC technicians or qualified maintenance personnel. Power down or set the thermostat to the OFF position before removing the old filter to prevent unfiltered air from pulling through the system. Confirm airflow direction matches the arrow printed on the filter frame before seating. Replace every 2 to 3 months or more frequently in high-dust or renovation environments.
