The NORDIC PURE 6x20x1CustomM13+C-6 is a custom-cut, pleated MERV 13 plus carbon air filter sold in a pack of six. It is designed for residential and light commercial HVAC systems, including forced-air furnaces and central air conditioning units. The filter combines a MERV 13 electrostatic media layer with an activated carbon layer to address both fine particulate capture and odor reduction. At a nominal size of 6 x 20 x 1 inches and an actual size of 5.5 x 19.5 x 0.75 inches, this filter is hand-fabricated to the listed dimensions. HVAC technicians and service professionals install it as a direct-fit replacement where standard stock sizes do not match the filter cabinet opening.
This filter is suited for residential forced-air systems where the filter slot does not accept a standard nominal size. It is built to the exact dimensions entered at the time of order, making it appropriate for older or custom-built air handler cabinets, non-standard return air grilles, and retrofit installations. The reinforced two-part frame provides structural stability during installation and over the full service life of the filter. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days depending on household environment, occupant sensitivity, and local air quality conditions.
Designed as a custom OEM-style replacement for residential and light commercial forced-air furnace and air conditioning systems requiring a filter with a nominal size of 6 x 20 x 1 inches and an actual size of 5.5 x 19.5 x 0.75 inches. Verify the actual opening dimensions before ordering, as custom-fabricated filters are not eligible for return.
Installation is performed by HVAC technicians or qualified service professionals. Always set the system thermostat to the off position and confirm the air handler has stopped before removing the existing filter. Check the airflow direction arrow on the filter frame and orient it so airflow travels from the return air side through the media toward the blower. Measure the actual filter cabinet opening to the nearest 1/8 inch before ordering a custom size to ensure a proper fit.
