The NORDIC PURE 17x21x1ExactCustomM13-6 is a custom-made, exact-size MERV 13 pleated air filter designed for residential and light commercial AC and furnace systems. With an actual size of 17 x 21 x 0.75 inches, this filter delivers high-efficiency mechanical filtration using an electrostatically charged media that attracts and traps fine airborne particles. The heavy-duty, moisture-resistant beverage board frame supports structural integrity, and the reinforced two-part frame construction adds durability over the filter service life. Sold in a six-pack, these filters are hand-cut to the exact dimensions specified at ordering and are manufactured in the USA.
These filters are intended for standard forced-air HVAC applications including residential gas furnaces, heat pumps, and central air conditioning systems where a 17 x 21 x 0.75-inch exact-fit filter is required. They suit households with pets, allergy sufferers, or anyone requiring finer particulate control than a MERV 8 or MERV 11 filter provides. Nordic Pure recommends replacing the filter every one to three months, with more frequent changes in environments with high dust loads, pets, or occupants with respiratory sensitivities. These are custom-fabricated units; verify your exact opening dimensions with a tape measure before ordering.
Designed as an exact-size custom replacement for residential and commercial forced-air HVAC systems requiring a filter with actual dimensions of 17 x 21 x 0.75 inches. Confirm the exact opening measurement of your air handler or furnace filter slot before ordering, as custom-fabricated filters are not returnable.
Air filter replacement is a routine maintenance task performed by HVAC technicians or knowledgeable property owners; always set the system thermostat to the off position and confirm the air handler has stopped before removing the old filter. Insert the new filter with the airflow arrow on the frame pointing toward the blower motor and away from the return air duct. Measure the actual filter slot opening with a tape measure before ordering custom sizes, as nominal size and actual size frequently differ. Dispose of the used filter in a sealed bag to contain trapped particulates.
