Nordic Pure 19_1/2x21x1ExactCustomM7-6 Merv 7 Filter 6pk

Product Description

The NORDIC PURE 19_1/2x21x1ExactCustomM7-6 is a custom-made, pleated AC furnace air filter rated MERV 7, sold in a 6-pack. This filter is hand-cut to exact dimensions of 19.5 x 21 x 0.75 inches to fit applications where standard nominal sizes do not match the actual filter opening. The electrostatically charged filter media captures lint, dust, pollen, pet dander, mold spores, and other common airborne particles in the 3-10 micron range, trapping 50 to 70 percent of particles in that size class. The moisture-resistant beverage board frame provides structural support and helps the filter maintain its shape throughout its service life. Licensed HVAC technicians and informed building maintenance staff are the primary installers of this product.

This filter is suited for residential and light commercial forced-air HVAC systems, including central air conditioning and gas or electric furnaces, where a custom exact-fit filter is required. The MERV 7 rating is comparable to MPR 600 filters used by some manufacturers. ASHRAE established the MERV rating scale as the industry standard for measuring filter efficiency. This 6-pack format supports regular filter rotation on a 1-to-3-month replacement schedule, which is recommended more frequently in homes with pets or occupants with allergies. The custom construction may use tape joinery to achieve the specified dimensions, which is standard for non-standard sizes.

Compatibility

Designed as a custom exact-fit replacement for residential and light commercial forced-air furnace and AC systems requiring a filter with actual dimensions of 19.5 x 21 x 0.75 inches. Measure the actual opening of the filter slot before ordering, as this is a custom-made size and not eligible for return.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Always shut down the HVAC system at the thermostat and disconnect power at the disconnect switch or breaker before removing the existing filter. Verify airflow direction arrows on the filter frame align with the direction of airflow into the blower. Because this is a custom-made product built to exact submitted dimensions, confirm measurements with a tape measure before ordering - custom sizes cannot be returned or exchanged.
