Nordic Pure 19_3/4x21x1ExactCustomM7-6 Merv 7 Filter 6 Pack

Product Description

The NORDIC PURE 19_3/4x21x1ExactCustomM7-6 is a custom-made pleated AC furnace air filter rated MERV 7, sized to exact dimensions of 19.75 x 21 x 0.75 inches and sold in a 6-pack. It is designed for residential and light commercial HVAC systems where a precise fit is required and standard nominal sizes are not available. The electrostatically charged filter media captures lint, dust, pollen, pet dander, mold spores, and dust mites while maintaining low airflow resistance. The heavy-duty, moisture-resistant beverage board frame provides structural integrity, and the media will not promote bacterial or mold growth on the filter surface. Licensed HVAC technicians and knowledgeable homeowners are the typical end users.

This filter fits HVAC systems requiring a non-standard custom size with an actual dimension of 19.75 x 21 x 0.75 inches. It is appropriate for residential forced-air furnaces, central air conditioning systems, and light commercial air handlers where indoor air quality improvement and allergen reduction are priorities. Custom construction may involve cutting down or combining standard filter frames, and tape may be used in assembly depending on the size. This filter is comparable in efficiency to filters rated MPR 600 by other manufacturer rating systems. Replacement is recommended every 1 to 3 months, with more frequent changes advised in homes with pets or allergy sufferers.

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
• Electrostatically charged filter media attracts and holds unwanted airborne particles more effectively than fiberglass alternatives
• Reinforced 2-part beverage board frame is moisture-resistant and built for balanced filtration and consistent airflow support
• Filter media does not promote bacterial or mold growth on the filter surface
• Custom-cut to exact dimensions for a precise fit where nominal sizes are unavailable
• Made in the USA

Compatibility

Designed as a custom exact-fit replacement filter for residential and light commercial HVAC systems, forced-air furnaces, and central air conditioning systems requiring an actual filter size of 19.75 x 21 x 0.75 inches. Because this is a custom size, verify your current filter actual dimensions before ordering. Custom-made filters are non-returnable.

Installation Notes

Installation is within the scope of HVAC technicians and qualified homeowners familiar with their air handling equipment. Always power down the HVAC system at the thermostat and disconnect power at the breaker before replacing a filter. Confirm airflow direction and install the filter with the directional arrow on the frame pointing toward the blower. Measure the actual opening in the filter rack, not the nominal size printed on the old filter, before ordering a custom size.
