Nordic Pure 21x23x1ExactCustomM7+C-6 Merv 7 Carbon Filter

Product Description

The NORDIC PURE 21x23x1ExactCustomM7+C-6 is a custom-cut, pleated AC and furnace air filter built to exact dimensions of 21 x 23 x 0.75 inches. Rated MERV 7 with an added carbon layer, it combines electrostatically charged synthetic media with activated carbon to capture airborne particulates and reduce odors in a single pass. The filter targets particles between 3 and 10 microns, including lint, household dust, pollen, pet dander, mold spores, and baking flour. It ships in a 6-pack and is installed by HVAC technicians or knowledgeable DIYers in residential or light-commercial forced-air systems.

This filter is sized for HVAC applications where a standard nominal size does not fit the filter housing. The actual dimensions of 21 x 23 x 0.75 inches are manufactured to fit the listed slot precisely. It is appropriate for residential gas furnaces, heat pumps, and central air conditioning systems that require a non-standard filter size. Custom construction uses a reinforced 2-part frame, which may incorporate tape depending on the final cut dimensions. Typical change interval is every 30 to 90 days depending on indoor and outdoor air quality conditions.

Key Features

• MERV 7 rating captures 50 to 70 percent of airborne particles between 3 and 10 microns
• Activated carbon layer reduces odors alongside particulate filtration
• Electrostatically charged synthetic media attracts and holds contaminants without restricting airflow
• Reinforced 2-part frame provides added structural durability compared to single-frame construction
• Custom exact-cut sizing to 21 x 23 x 0.75 inches for non-standard filter slots
• Made in the USA

Compatibility

Custom-made to exact dimensions for forced-air HVAC systems requiring a non-standard filter size. Intended for filter slots where the actual opening measures 21 x 23 x 0.75 inches. This is a non-returnable custom size; measure the existing filter or housing before ordering.

Installation Notes

Licensed HVAC technicians and qualified DIYers can install this filter. Always shut down the air handler or furnace at the disconnect or thermostat before removing or installing a filter. Confirm airflow direction arrows on the filter frame align with the direction of air movement toward the blower. Replace every 30 to 90 days or as conditions require; high-dust or high-pet-dander environments typically need more frequent changes.
