The NORDIC PURE 18x20x1M14+C-6 is a pleated MERV 14 air filter with an integrated activated carbon layer, sold in a 6-pack. The electrostatically charged synthetic media captures fine airborne particulates while the activated carbon component adsorbs odorous gases, VOCs, and smoke vapors. With a nominal size of 18x20x1 inches and an actual size of 17.5 x 19.5 x 0.75 inches, this filter is rated MERV 14, equivalent to MPR 2800. It is installed by HVAC technicians and knowledgeable homeowners in forced-air heating and cooling systems that are rated to handle MERV 14 or higher filtration levels.
This filter is suited for residential and light-commercial forced-air systems where both fine particulate control and odor reduction are required. The dual-media construction makes it a practical choice in environments with pets, smokers, or high VOC exposure. Because MERV 14 filters restrict airflow more than lower-rated media, the system must be rated to handle this filtration level. Nordic Pure MERV 14 Plus Carbon filters are particularly well-suited for newer, high-efficiency systems designed to accept MERV 13 and above media. Replacement interval is typically every 30 to 90 days depending on indoor and outdoor air quality conditions.
Designed as an OEM-style replacement pleated air filter for residential and light-commercial forced-air HVAC systems with a nominal 18x20x1 inch filter slot. System must be rated to handle MERV 14 or higher filters; confirm blower and duct design before installation.
Licensed HVAC technicians and qualified homeowners install this filter type. Power down the air handler before replacing the filter. Confirm the airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Measure the actual filter slot dimensions before ordering, as nominal sizes do not always match actual dimensions; the actual size of this filter is 17.5 x 19.5 x 0.75 inches.
