Nordic Pure 20x24x1M7+C-4 Merv 7 Plus Carbon Filter 4 Pack

Product Description

The NORDIC PURE 20x24x1M7+C-4 is a MERV 7 pleated air filter with an integrated activated carbon layer, sold in a 4-pack. The electrostatically charged synthetic media captures large airborne particulates while the flat activated carbon panel adsorbs odorous gases and volatile organic compounds (VOCs). The nominal size is 20 by 24 by 1 inch, with an actual size of 19.5 by 23.44 by 0.75 inches. This filter is designed for use in residential and light commercial forced-air HVAC systems, including central air conditioning and gas or electric furnaces. Licensed HVAC technicians and informed homeowners typically install this filter as part of routine preventive maintenance.

The 20x24x1M7+C-4 suits residential and light commercial HVAC applications where basic particulate control and odor reduction are both required. Typical install scenarios include homes with pets, smokers, or allergy-sensitive occupants who need a step up from standard fiberglass or poly disposable filters. The antimicrobial media helps suppress bacterial and mold growth within the filter material itself, supporting cleaner airflow through each system pass. Replacement is recommended every 30 to 90 days depending on indoor air quality conditions and usage, or more frequently during renovation or high-dust periods.

Compatibility

Designed as an OEM-style replacement filter for residential and light commercial forced-air furnace and air conditioning systems that accept a nominal 20 by 24 by 1 inch filter. Verify actual slot dimensions against the actual filter size of 19.5 by 23.44 by 0.75 inches before installation.

Installation Notes

Installation is performed by licensed HVAC technicians or knowledgeable homeowners. Always set the system thermostat to the off position and confirm the air handler or furnace fan has stopped before removing the existing filter. Insert the new filter with the airflow arrow on the frame pointing toward the blower, not the return. Replace every 30 to 90 days to maintain rated filtration efficiency and protect system components.
