Nordic Pure 13x21x1ExactCustomM7-6 Merv 7 Furnace Filter 6pk

Product Description

The NORDIC PURE 13x21x1ExactCustomM7-6 is a custom-cut, MERV 7 pleated air filter designed for residential and light commercial HVAC systems. Manufactured to exact dimensions of 13 inches by 21 inches by 0.75 inches, this filter captures lint, dust, pollen, pet dander, mold spores, and dust mites as air passes through the pleated media. The electrostatically charged filtration material improves particle attraction without restricting airflow, and the moisture-resistant beverage board frame provides structural integrity. Sold in a 6-pack, this SKU is hand-fabricated to the listed dimensions and is non-returnable due to its custom-made nature.

This filter is suited for residential forced-air furnaces and central air conditioning systems where a nominal 13x21x1 filter slot is used. It is appropriate for homes with pets, allergy sufferers, or environments with elevated dust levels. The MERV 7 rating makes it a practical upgrade over standard fiberglass filters in applications where improved particulate control is needed without placing excessive static pressure on the air handler. Nordic Pure notes this MERV 7 rating is comparable to filters carrying an MPR 600 designation from other manufacturers. Custom sizing makes this filter relevant for non-standard or older filter housings that do not accept mass-produced nominal sizes.

Key Features

• MERV 7 rated media captures 50 to 70 percent of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores
• Electrostatically charged pleated media attracts particles without promoting bacterial or mold growth on the filter surface
• Moisture-resistant beverage board frame with reinforced 2-part construction for added durability and consistent airflow support
• Custom-fabricated to exact dimensions of 13 inches by 21 inches by 0.75 inches - not a nominal-size filter
• Made in the USA
• Sold as a 6-pack; recommended replacement interval of 1 to 3 months depending on environment

Compatibility

Designed as a custom exact-fit replacement for HVAC systems requiring a 13 inches by 21 inches by 0.75 inches actual-size filter. Verify the exact dimensions of your current filter before ordering, as custom sizes are not eligible for return. Nominal size is listed as 13x21x1; actual size differs and should be confirmed with a tape measure prior to purchase.

Installation Notes

Filter installation and replacement is typically performed by HVAC technicians or qualified service personnel, though homeowner replacement is common in residential applications. Always shut down the HVAC system at the thermostat and, where practical, at the disconnect or breaker before removing the old filter. Note the airflow direction arrow on the filter frame and install with that arrow pointing toward the air handler or blower. Because this is a custom-cut filter, confirm the actual slot dimensions match the filter dimensions listed above before installation.
