Nordic Pure 13x21x1ExactCustomM8+C-12 Merv 8 Carbon Filter

Product Description

The NORDIC PURE 13x21x1ExactCustomM8+C-12 is a custom-cut, MERV 8 pleated air filter with activated carbon, designed for residential and light commercial AC and furnace systems. Built from electrostatically charged synthetic media, it captures particles between 3 and 10 microns at a 70 to 85 percent efficiency rate, including lint, dust, pollen, pet dander, mold spores, and odors. The carbon layer provides additional odor reduction beyond standard MERV 8 filtration. This filter ships in a 12-pack and is manufactured to exact dimensions, making it a custom-order item suited for non-standard filter slots that standard nominal sizes cannot fit.

This filter is intended for residential and light commercial HVAC applications where the filter slot requires an exact-fit custom size rather than a standard nominal cut. The actual dimensions are 13 inches by 21 inches by 0.75 inches, constructed to fit precisely in slots that a standard 13x21x1 nominal filter would not seat correctly. Installers should measure the existing filter slot carefully before ordering, as this is a custom-fabricated product. The reinforced 2-part frame supports consistent airflow and structural integrity throughout the filter service life. Replacement is recommended every 30 to 90 days depending on environmental conditions.

Installation Notes

This filter is installed by HVAC technicians or qualified service personnel. Power down the HVAC system before removing the old filter and installing the replacement. Verify airflow direction markings on the filter frame before seating and confirm the filter fits flush with no gaps around the perimeter. Because this is a custom-cut product, return to the supplier to confirm exact slot dimensions prior to ordering if measurements are uncertain.
