Nordic Pure 21x23x1ExactCustomM12-6 Merv 12 Filter 6pk

Product Description

The NORDIC PURE 21x23x1ExactCustomM12-6 is a custom-cut, pleated AC furnace air filter rated MERV 12, sold in a 6-pack. It targets airborne particles down to 1 micron, capturing lint, dust, pollen, pet dander, mold spores, smoke, bacteria, and virus carriers. The electrostatically charged filter media improves particle attraction without significantly restricting airflow. The frame is constructed from a heavy-duty, moisture-resistant beverage board. Nominal size is 21 x 23 x 1 inches; actual size is 21 x 23 x 0.75 inches. Licensed HVAC technicians and experienced HVAC service professionals typically handle installation in both residential and light commercial applications.

This filter is suited for residential and commercial HVAC systems where high-efficiency particle capture is required without excessive static pressure drop. It fits in standard 1-inch filter slots and is especially appropriate for households with pets, allergy sufferers, or environments with elevated dust loads such as renovation or construction zones. Nordic Pure recommends replacing the filter every 1 to 3 months depending on environmental conditions, with more frequent replacement in high-particulate environments. Because these are custom-made to exact dimensions, they are non-returnable and should only be ordered after verifying the exact installed filter size.

Key Features

• MERV 12 efficiency: captures over 90% of particles between 3 and 10 microns, and 80% to 90% of particles between 1 and 3 microns
• Electrostatically charged media attracts fine airborne particles and does not promote bacterial or mold growth on the filter surface
• Reinforced 2-part beverage board frame provides structural durability and maintains shape under normal HVAC airflow pressure
• Custom-cut to exact nominal dimensions of 21 x 23 x 1 inches (actual: 21 x 23 x 0.75 inches) for precise fitment
• Comparable to MPR 1500-1900 rated filters; follows ASHRAE MERV rating standard
• Made in the USA

Compatibility

Designed as a custom-fit replacement for residential and commercial HVAC systems using a 1-inch filter slot with a nominal filter opening of 21 x 23 x 1 inches. Verify actual installed filter dimensions before ordering, as nominal and actual sizes frequently differ.

Installation Notes

HVAC technicians and qualified service professionals should power down the air handler or furnace at the disconnect before servicing the filter compartment. Note the airflow direction arrow printed on the filter frame and install with the arrow pointing toward the blower. Because this is a custom-cut filter, verify the actual slot dimensions against the filter actual size of 21 x 23 x 0.75 inches before installation. Custom sizes are non-returnable, so confirm measurements to the fraction of an inch prior to ordering.
