Nordic Pure 13x21x1ExactCustomM8+C-6 Merv 8 Carbon Filter

Product Description

The NORDIC PURE 13x21x1ExactCustomM8+C-6 is a custom-cut, MERV 8 pleated air filter with activated carbon media, sized at an exact 13 x 21 x 0.75 inches and sold in a six-pack. It is engineered for residential and light-commercial HVAC systems where a non-standard filter slot requires precise dimensions. The electrostatically charged synthetic media captures particles in the 3-10 micron range at 70-85% efficiency, while the carbon layer adsorbs common household odors. HVAC technicians and facilities maintenance personnel install this filter in forced-air furnaces and air handlers where standard nominal sizes do not fit the existing filter rack.

This filter is intended for forced-air heating and cooling systems that require a custom slot size of 13 x 21 x 1 nominal. The exact actual dimensions are 13 x 21 x 0.75 inches, which is consistent with industry practice for filters listed at a 1-inch nominal thickness. It is suitable for residential split systems, packaged units, and horizontal or vertical air handlers where slot width and height must be matched precisely. The six-pack format supports a standard 30-90 day replacement cycle over an extended service interval without repeated ordering.

Key Features

• MERV 8 filtration captures 70-85% of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores
• Activated carbon layer reduces common household odors passing through the filter media
• Electrostatically charged synthetic pleated media provides low airflow resistance to reduce static pressure drop on the HVAC system
• Reinforced 2-part frame construction is built for durability and consistent dimensional integrity across the filter face
• Custom exact-cut dimensions of 13 x 21 x 0.75 inches to fit non-standard filter slots; manufactured to the nominal size listed
• Made in the USA

Compatibility

Designed as a custom exact-size replacement filter for forced-air furnaces and air handlers requiring a 13 x 21 x 1 nominal slot with an actual opening that accepts a 13 x 21 x 0.75 inch filter. Because this is a custom-cut size, verify the actual opening dimensions of the existing filter rack before ordering, as custom sizes are non-returnable.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified maintenance personnel. Always set the system thermostat to the off position and confirm the air handler or furnace blower has stopped before removing the old filter. Insert the new filter with the airflow arrow on the frame pointing toward the blower and away from the return air side. Custom-cut filters use a reinforced multi-part frame that may include taped seams; inspect the frame for a secure fit against the filter rack to prevent bypass air around the filter edges.
