The NORDIC PURE 8_1/2x30x1ExactCustomM7+C-6 is a custom-made, pleated MERV 7 plus carbon air filter for residential and light-commercial HVAC systems. It ships in a 6-pack and is cut to exact dimensions of 8.5 x 30 x 0.75 inches to fit non-standard filter slots where a nominal off-the-shelf size will not seat correctly. The MERV 7 rating captures 50 to 70 percent of airborne particles between 3 and 10 microns, while an integrated carbon layer targets household odors. The reinforced two-part frame supports balanced airflow and structural integrity over the filter life. HVAC technicians and homeowners with non-standard equipment openings order this filter when a standard nominal size does not match the actual slot measurement.
This filter is suited to residential forced-air gas furnaces, heat pumps, and central air conditioning air handlers where the return-air filter slot measures 8.5 x 30 x 0.75 inches actual. Because dimensions are custom-cut to the exact measurements provided at order, the filter is intended for systems where standard nominal sizes leave gaps at the frame edges. A 1-inch nominal filter in this size family is recommended for replacement every 30 to 90 days depending on household dust load, pet presence, and local air quality. Six filters per box provides a full maintenance cycle supply for most single-system installations.
Designed for forced-air HVAC systems with a return-air filter slot requiring an actual filter size of 8.5 x 30 x 0.75 inches. Before ordering any custom-size filter, measure the actual opening with a tape measure. The actual width and length of the installed filter should be within 0.125 inches of the slot dimension; if outside that tolerance, a different custom size is required. Custom-made filters are not interchangeable with nominal standard sizes.
Power down or set the thermostat to off before removing the old filter to avoid drawing unfiltered air through the system during changeout. Confirm airflow direction is marked on the filter frame and install with the arrow pointing toward the blower. Custom-cut filters should be handled carefully at the edges to avoid frame deformation that could allow bypass air around the media. Dispose of used filters per local waste guidelines; no special handling is required for the carbon media under standard residential maintenance codes.
