Nordic Pure 17x20x1CustomM7-12 Merv 7 Furnace Filter 12pk

Product Description

The NORDIC PURE 17x20x1CustomM7-12 is a custom-made MERV 7 pleated air filter designed for residential and light commercial HVAC systems, including forced-air furnaces and central air conditioners. Sold in a 12-pack, each filter measures an actual 16.5 x 19.5 x 0.75 inches, fitting openings with a nominal 17x20x1 designation. The electrostatically charged filter media captures lint, dust, pollen, pet dander, mold spores, and dust mites, trapping 50 to 70 percent of airborne particles in the 3 to 10 micron range. The heavy-duty, moisture-resistant beverage board frame adds structural integrity without restricting airflow. These filters are manufactured in the USA and are custom-cut to the dimensions listed at time of order.

This filter suits residential homes and commercial office environments where balanced filtration and low airflow resistance are priorities. MERV 7 efficiency is comparable to an MPR 600 rating. ASHRAE-standard MERV ratings govern the efficiency measurement. These filters are appropriate for systems where occupants deal with common allergens such as pollen, pet dander, or dust. Nordic Pure recommends replacing filters every 1 to 3 months, with more frequent changes in homes with pets or allergy sufferers. Because these are custom-made to exact dimensions, they are produced by cutting down or combining standard filter frames, and tape may be used to achieve the specified size.

Compatibility

Designed as a custom OEM-style replacement for residential and commercial forced-air furnace and AC systems requiring a nominal 17x20x1 filter slot. Verify the actual opening dimensions against the listed actual size of 16.5 x 19.5 x 0.75 inches before ordering. Custom sizes are not eligible for returns, so confirm measurements with a tape measure prior to purchase.

Installation Notes

Filter replacement in forced-air HVAC systems is typically performed by HVAC technicians or knowledgeable property owners. Power down or set the system to off at the thermostat before removing the existing filter. Note the airflow direction arrow on the filter frame and orient the replacement filter so the arrow points toward the blower. Filters should be inspected monthly and replaced every 1 to 3 months depending on usage and air quality conditions.
