Nordic Pure 18x25x1M7+C-3 Merv 7 Plus Carbon Air Filter 3 Pack

Product Description

The NORDIC PURE 18x25x1M7+C-3 is a pleated MERV 7 air filter with activated carbon enhancement, sold in a 3-pack for residential HVAC systems. The filter media is electrostatically charged synthetic material that captures airborne particulates, while an added flat panel infused with activated charcoal adsorbs odorous gases and volatile organic compounds (VOCs). The antimicrobial, hypoallergenic filter media resists bacterial and mold growth. The actual size is 17.5 x 24.5 x 0.75 inches, fitting nominal 18x25x1 filter slots. A heavy-duty moisture-resistant beverage board frame and a bonded metal mesh support grid maintain structural integrity across the service life of the filter.

This filter is suited for residential forced-air furnace and central air conditioning systems where both particulate control and odor reduction are priorities. Typical applications include homes with pets, smokers, or occupants sensitive to airborne allergens. NORDIC PURE rates this filter equivalent to an MPR 600 filter. Filter replacement is recommended every 30 to 90 days depending on indoor and outdoor conditions, with more frequent changes advised during home renovation or high-dust periods.

Installation Notes

Installation is performed by HVAC technicians or qualified DIYers as part of routine filter maintenance. Power down or set the thermostat to off before opening the filter compartment to prevent unfiltered air from circulating during the swap. Confirm the airflow direction arrow on the filter frame is oriented toward the blower before closing the access panel. Follow local codes and system manufacturer guidelines for filter change intervals.
