The NORDIC PURE 18x24x4M14+C-2 is a high-efficiency MERV 14 pleated air filter with activated carbon, sold as a 2-pack. It combines electrostatically charged synthetic filter media with a flat-panel activated charcoal layer to capture airborne particulates and adsorb odorous gases and volatile organic compounds (VOCs). The pleated media captures more than 90% of 1.0-10.0 micron particles and up to 85% of 0.30-1.0 micron particles. Contaminants trapped include lint, household dust, pollen, dust mite debris, pet dander, smoke, smog, mold spores, and bacteria. The frame is a heavy-duty, moisture-resistant beverage board construction with a metal mesh support grid bonded to the pleats. A licensed HVAC technician or knowledgeable installer handles this filter in residential or light-commercial forced-air systems.
This filter is suited for residential and light-commercial HVAC systems rated to handle MERV 14 filtration and above. Because of the high filtration efficiency and corresponding airflow restriction, it is important to confirm your system is rated for MERV 14 before installation. It performs well in newer, high-efficiency systems that typically use HEPA-class filtration. The carbon layer provides odor control that makes this filter a good fit for households with pets, cooking odors, or other indoor air quality concerns. The nominal size is 18 x 24 x 4 inches; the actual size is 17.5 x 23.38 x 3.63 inches. Always measure your filter slot before ordering to confirm fit.
Designed as a direct-fit replacement for standard 18 x 24 x 4 inch (actual size 17.5 x 23.38 x 3.63 inches) filter slots in residential and light-commercial forced-air HVAC systems rated for MERV 14 filtration. Confirm system rating before installing filters at MERV 14 or higher.
Installation is performed by a licensed HVAC technician or qualified service professional. Power down the HVAC system at the thermostat and, where applicable, at the disconnect before removing the old filter. Confirm airflow direction by checking the arrow printed on the filter frame and orient the filter accordingly in the slot. Nordic Pure recommends replacing this filter every 3 to 6 months, though actual service life varies based on indoor and outdoor air conditions.
