The NORDIC PURE 12x24x4M13+C-6 is a MERV 13 pleated air filter with activated carbon, sold in a 6-pack. The filter media is electrostatically charged synthetic material rated to capture more than 90% of 1.0-10.0 micron particulates and up to 75% of 0.30-1.0 micron particulates. An integrated flat-panel activated carbon layer adsorbs odorous gases, vapors, and volatile organic compounds (VOC) while maintaining low pressure drop across the system. The heavy-duty beverage board frame is moisture resistant, and a bonded metal mesh support grid holds pleat geometry under airflow. Licensed HVAC technicians and mechanical contractors install this filter in forced-air heating and cooling systems serving residential and light commercial applications.
This filter fits standard 4-inch filter housings in residential and light commercial forced-air systems. It is suited for environments where both fine particulate control and odor reduction are required, such as homes with pets, smokers, or occupants with allergies or respiratory sensitivities. The nominal size is 12x24x4 inches with an actual size of 11.5 x 23.38 x 3.63 inches. Nordic Pure recommends replacing this filter every 3-6 months depending on indoor and outdoor air quality conditions, with more frequent changes recommended during construction, renovations, or periods of high outdoor pollution.
Designed as a direct-fit replacement for standard 4-inch pleated filter housings that accept a nominal 12x24x4 inch filter. Actual dimensions are 11.5 x 23.38 x 3.63 inches; confirm the actual slot dimensions before ordering, as nominal and actual filter sizes frequently differ across equipment brands.
Installation is performed by a licensed HVAC technician or qualified service professional. Set the thermostat to the off position and shut down the air handler or furnace at the unit disconnect before replacing the filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Inspect the filter housing for bypasses or gaps that could allow unfiltered air to enter the system.
