Nordic Pure 13x21x1ExactCustomM10+C-12 Merv 10 Filter 12pk

Product Description

The NORDIC PURE 13x21x1ExactCustomM10+C-12 is a custom-cut, MERV 10 pleated air filter with activated carbon, sized to exact dimensions for AC and furnace systems where standard sizes do not fit. The filter media is electrostatically charged synthetic material that attracts and captures airborne particulates down to 3 microns, including lint, household dust, pollen, pet dander, mold spores, and odors. The carbon layer targets gaseous contaminants. At 13 x 21 x 0.75 inches actual size, this filter is manufactured to precise dimensions and comes in a 12-pack for extended service intervals. HVAC technicians and service pros install these in forced-air residential and light commercial systems requiring non-standard filter sizing.

This filter is suited for residential and light commercial forced-air HVAC systems where the filter slot requires a 13 x 21 x 1 nominal opening but the actual clearance measures 13 x 21 x 0.75 inches. The MERV 10 rating makes it appropriate for environments with elevated particulate loads such as homes with pets, allergy concerns, or high dust activity. The added carbon layer addresses household odors from cooking, pets, and similar sources. Filters should be replaced every 30 to 90 days depending on system load and environmental conditions. This is a custom-made product and is not eligible for return.

Compatibility

Designed for forced-air AC and furnace systems requiring a 13 x 21 x 1 nominal filter size with an actual opening of 13 x 21 x 0.75 inches. Verify actual slot dimensions with a tape measure before ordering. Custom sizes are non-returnable.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Power down the air handler or furnace at the disconnect or breaker before replacing the filter. Confirm airflow direction marked on the filter frame matches the direction of airflow in the system before seating the filter. Because this is a custom-cut product, verify actual slot dimensions with a tape measure prior to ordering, as custom-made filters are not eligible for return.
