The NORDIC PURE 19x21_1/2x1ExactCustomM7-6 is a custom-cut pleated air filter rated MERV 7, designed for residential and light commercial AC and furnace systems. The actual dimensions are 19 x 21.5 x 0.75 inches. This six-pack delivers consistent mechanical and electrostatic filtration, capturing lint, dust, pollen, pet dander, mold spores, and dust mites on each pass through the air handler. The filter media is electrostatically charged to attract fine particles and is manufactured using a moisture-resistant beverage board frame. At MERV 7, this filter captures 50 to 70 percent of airborne particles between 3 and 10 microns while maintaining low airflow resistance to keep the HVAC system running efficiently.
This filter is suited for residential homes and commercial office environments where regular filter replacement is part of a routine HVAC maintenance program. The custom size is hand-fabricated to exact dimensions, which makes it appropriate for return air grilles or filter cabinets that do not accept standard nominal sizes. ASHRAE MERV 7 performance is roughly comparable to MPR 600-rated filters from other manufacturers. Filter replacement every one to three months is typical, with more frequent changes recommended in homes with pets or occupants with allergy sensitivities. Depending on the size configuration, the frame may incorporate tape joints to achieve the specified custom dimensions.
Custom-fabricated as an exact-fit replacement for AC and furnace return air filter slots requiring an actual size of 19 x 21.5 x 0.75 inches. Measure the existing filter or filter slot before ordering, as custom sizes are non-returnable and are built to the dimensions specified at time of order.
Installation is performed by HVAC technicians or qualified service personnel. Power down or set the thermostat to the off position before removing the existing filter to prevent unfiltered air from bypassing into the air handler. Verify airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Because these filters are custom-cut and may incorporate taped frame joints, handle with care during installation to maintain frame integrity.
