Nordic Pure 20x21x1ExactCustomM14-12 Merv 14 Filter 12pk

Product Description

The NORDIC PURE 20x21x1ExactCustomM14-12 is a custom-cut, pleated AC furnace air filter rated MERV 14, sold in a 12-pack. It is designed for residential and commercial HVAC systems that require a nominal 20x21x1 filter with an actual size of 20 x 21 x 0.75 inches. The electrostatically charged filter media captures over 90% of airborne particles between 1 and 10 microns, and 75% to 95% of particles between 0.3 and 1 microns. Targeted contaminants include lint, dust, pollen, pet dander, mold spores, smoke, bacteria, virus carriers, and smog. The frame is constructed from a heavy-duty, moisture-resistant beverage board and is manufactured in the USA.

This filter is suited for residential homes and light commercial spaces where high-efficiency air filtration is a priority. It fits HVAC systems - including newer high-efficiency units - that are rated to handle MERV 14 filters and above. Because MERV 14 filtration increases airflow restriction compared to lower-rated filters, the system must be rated to support it. These filters are custom-made to the exact nominal dimensions of 20 x 21 x 1 inches, making them appropriate for units that require a precise fit rather than a standard off-the-shelf size. Replacement is recommended every 1 to 3 months, with more frequent changes in homes with pets or allergy sufferers.

Key Features

• MERV 14 rating captures over 90% of particles from 1 to 10 microns and 75% to 95% of particles from 0.3 to 1 microns
• Electrostatically charged media attracts airborne particles and does not promote bacterial or mold growth on the filter surface
• Heavy-duty, moisture-resistant beverage board frame with reinforced 2-part construction for added durability
• Custom-cut to exact nominal dimensions - hand-made per order using cut-down or combined frames; tape may be used depending on size
• Comparable to filters rated MPR 2800 on manufacturer-specific rating scales
• Made in the USA

Compatibility

Custom-made as an exact-fit replacement for HVAC systems requiring a nominal 20x21x1 filter. Intended for use in systems rated to handle MERV 14 filtration and above, including newer high-efficiency units designed for HEPA-grade filtration. Verify the actual opening dimensions of the filter slot before ordering, as this is a non-returnable custom size.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Always shut down the HVAC system at the thermostat and disconnect power at the air handler before removing or installing the filter. Confirm the actual slot dimensions with a tape measure before ordering, as custom-cut filters are not eligible for return. Check the filter monthly and replace every 1 to 3 months, or more frequently in high-traffic or high-allergen environments.
