Nordic Pure 13x21_1/2x1CustomM12+C-6 Merv 12 Plus Carbon Filter

Product Description

The NORDIC PURE 13x21_1/2x1CustomM12+C-6 is a custom-cut, MERV 12 pleated carbon air filter sold in a 6-pack, designed for residential and light-commercial AC and forced-air furnace systems. With an actual size of 12.75 x 21.5 x 0.75 inches, this filter is hand-fabricated to exact dimensions from the nominal 13 x 21.5 x 1 inch specification. The MERV 12 rating means it captures over 90% of airborne particles between 3 and 10 microns, and 80% to 90% of particles between 1 and 3 microns. The activated carbon layer targets odors in addition to particulate. HVAC technicians and homeowners in non-standard duct configurations order this filter when no off-the-shelf size fits their system.

This filter is suited for residential forced-air furnace and central air conditioning systems with non-standard filter slots that require a custom nominal size of 13 x 21.5 x 1 inch. Because the filter is hand-made to order by cutting down or combining standard filter frames, it addresses duct openings that fall outside typical stocked dimensions. For 1-inch filters in most residential applications, replacement intervals of 30 to 90 days are recommended depending on household conditions such as pets, dust load, and air quality. Each 6-pack order provides a full supply cycle for routine filter changes.

Compatibility

Custom-made to fit forced-air furnace and central AC systems requiring a nominal filter size of 13 x 21.5 x 1 inch. Because this is a non-standard custom size, measure the existing filter slot to confirm actual opening dimensions before ordering. The actual filter size is 12.75 x 21.5 x 0.75 inches.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified service personnel. Power down the air handler or furnace at the disconnect or breaker before removing the existing filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Because this is a custom-made product fabricated to the dimensions specified at the time of order, verify measurements carefully before ordering - custom sizes cannot be returned.
