Nordic Pure 13x21x1ExactCustomM14+C-12 Merv 14 Filter

Product Description

The NORDIC PURE 13x21x1ExactCustomM14+C-12 is a custom-cut, pleated AC and furnace air filter rated MERV 14 with activated carbon media. It is designed for residential and light commercial HVAC systems where high-efficiency particulate and odor control are required. The electrostatically charged synthetic 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. The added carbon layer addresses odors, smoke, and chemical vapors that standard pleated filters do not address. Licensed HVAC technicians and experienced DIYers install these filters as direct replacements in forced-air systems.

This filter is sized at an exact nominal 13 x 21 x 1 inches, with an actual dimension of 13 x 21 x 0.75 inches. It is manufactured to custom dimensions and is intended for systems where standard nominal sizes do not fit correctly. The 12-pack quantity suits preventive maintenance programs where filters are changed on a 30-to-90-day cycle. Applications include residential gas furnaces, heat pumps, and split-system air handlers where the filter slot accepts a 1-inch media filter with the listed nominal opening.

Key Features

• MERV 14 rating captures over 90% of particles between 1 and 10 microns, including pollen, pet dander, mold spores, bacteria, and smoke
• Activated carbon layer reduces odors, smoke, and chemical vapors beyond what particulate-only filters provide
• Electrostatically charged synthetic media attracts and holds fine airborne particulates without significantly restricting airflow
• Reinforced 2-part frame construction provides added structural rigidity for custom-cut sizes
• Exact custom sizing at 13 x 21 x 0.75 inches actual for applications where standard nominal sizes do not fit
• Made in the USA; sold in a 12-pack for scheduled filter replacement programs

Compatibility

Designed as a custom-size OEM-style replacement for residential and light commercial forced-air HVAC systems requiring a 13 x 21 x 1 inch nominal filter slot. Because this is a custom-made size, verify the actual opening dimensions before ordering. Custom sizes are non-returnable; measure the existing filter or filter slot before purchase.

Installation Notes

HVAC technicians and qualified service professionals typically install pleated furnace filters. Always set the system thermostat to off and shut down power to the air handler or furnace at the disconnect before replacing the filter. Note the airflow direction arrow printed on the filter frame and orient the new filter so the arrow points toward the blower. Custom-cut frames may use reinforced tape construction; inspect the frame for integrity before installation and do not force-fit a filter into an undersized opening.
