Nordic Pure 21x27x1CustomM13+C-6 Merv 13 Carbon Filter 6pk

Product Description

The NORDIC PURE 21x27x1CustomM13+C-6 is a custom-made, pleated carbon air filter rated MERV 13, sold in a 6-pack. It is designed for residential and light-commercial HVAC systems, including furnaces and central air conditioning units, where enhanced particulate and odor control are required. The filter combines a MERV 13 electrostatic media with an activated carbon layer to address both fine airborne particles and household odors in a single filter change. Actual dimensions are 20.5 x 26.25 x 0.75 inches, making this a custom size cut to order. HVAC technicians and knowledgeable homeowners install this filter as a direct drop-in for systems requiring a 21x27x1 nominal slot.

This filter fits residential and light-commercial forced-air HVAC systems with a nominal 21x27x1 filter slot. It is particularly suited to environments with elevated allergen loads, pet dander, smoke, or odor concerns. The activated carbon layer addresses volatile organic compounds and household odors alongside the particulate filtration the MERV 13 media provides. Because this is a custom-cut size, it is manufactured to the exact listed dimensions and is not a stock standard size. Measure the existing filter before ordering to confirm the actual opening dimensions match the 20.5 x 26.25 x 0.75 inch actual size of this unit.

Key Features

• MERV 13 rated media captures over 90% of airborne particles between 1 and 10 microns, and 50% to 70% of particles between 0.3 and 1 micron, including pollen, dust, pet dander, mold spores, smoke, bacteria, and viruses
• Activated carbon layer reduces household odors and VOC-related contaminants in the airstream
• Reinforced 2-part frame construction provides structural support and balanced airflow across the filter face
• Custom-cut to actual dimensions of 20.5 x 26.25 x 0.75 inches for a precise fit in non-standard filter openings
• Sold as a 6-pack to reduce service frequency and per-unit cost
• Made in the USA

Compatibility

Designed as a custom OEM-style replacement for forced-air furnace and central AC systems requiring a nominal 21x27x1 filter slot with an actual opening of approximately 20.5 x 26.25 inches. Confirm actual filter bay dimensions before ordering, as this is a non-returnable custom size.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified service personnel. Power down the air handler or furnace at the disconnect and thermostat before removing the existing filter. Confirm airflow direction arrows on the new filter frame align with the direction of airflow into the blower. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days depending on environmental conditions; high-dust or high-pet-dander environments will shorten service intervals. Because this is a custom-manufactured size, verify actual slot dimensions with a tape measure prior to ordering, as returns are not accepted on custom filters.
