Nordic Pure 19x21x1CustomM7+C-6 Merv 7 Carbon Filter 6pk

Product Description

The NORDIC PURE 19x21x1CustomM7+C-6 is a custom-made, pleated MERV 7 plus carbon air filter designed for residential and light-commercial AC and furnace systems. Supplied in a 6-pack, each filter measures 18.5 x 20.5 x 0.75 inches actual size and is hand-cut to match the exact nominal dimensions ordered. The carbon layer addresses common household odors alongside standard particulate filtration. These filters are built for 1-inch filter slots and are manufactured to order, so accurate field measurement of the existing filter is required before purchasing.

This filter is suited for residential forced-air HVAC systems where a standard size does not fit and a custom nominal dimension of 19x21x1 is required. Typical installations include gas furnaces and central air handlers with non-standard filter rack openings. The MERV 7 rating provides efficient filtration while maintaining low static pressure drop, making it appropriate for systems where airflow resistance is a concern. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days depending on indoor air quality and environmental conditions.

Key Features

• MERV 7 rating captures 50 to 70 percent of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores
• Activated carbon layer targets common household odors for combined particulate and odor control
• Custom nominal size of 19x21x1 with an actual size of 18.5 x 20.5 x 0.75 inches, hand-fabricated to order
• Reinforced 2-part frame construction for added structural durability during the service interval
• Low airflow resistance design helps maintain system efficiency and extends filter service life
• Made in the USA

Compatibility

Designed as a custom OEM-style replacement for residential and light-commercial forced-air furnace and air conditioning systems requiring a 19x21x1 nominal filter size. Verify the actual opening dimensions before ordering, as custom sizes are non-returnable.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Power down the air handler or furnace at the disconnect before servicing the filter compartment. Confirm the actual filter slot dimensions with a tape measure prior to ordering, as the actual filter size is 18.5 x 20.5 x 0.75 inches and must fit within 1/8 inch of the opening. Because these filters are custom-made to order, they are not eligible for return.
