Nordic Pure 12_1/2x21x1ExactCustomM13+C-6 Merv 13 Filter

Product Description

The NORDIC PURE 12_1/2x21x1ExactCustomM13+C-6 is a custom-cut pleated air filter with activated carbon media, rated MERV 13, and sold in a 6-pack. It is designed to fit HVAC air handlers and forced-air furnace systems where non-standard filter openings require exact-measurement sizing. The filter measures 12.5 x 21 x 0.75 inches actual size. MERV 13 filtration captures over 90 percent of airborne particles between 1 and 10 microns and 50 to 70 percent of particles between 0.3 and 1 micron. The carbon layer adds odor-reduction capability beyond standard mechanical filtration. This filter is manufactured to the dimensions specified at the time of order and is hand-cut to match the exact size entered.

This filter is intended for residential and light-commercial forced-air HVAC systems with non-standard filter cabinet dimensions that standard off-the-shelf sizes cannot accommodate. Typical applications include older ductwork configurations, custom-built air handler cabinets, and retrofit installations where nominal sizes do not fit correctly. Because this is a custom-made product built to the exact dimensions ordered, the actual filter size is 12.5 x 21 x 0.75 inches. Installers and homeowners should measure the existing filter opening with a tape measure before ordering, verifying width and length to within 0.125 inches of the opening. This product ships as a 6-pack and is suitable for 1-inch filter tracks.

Key Features

• MERV 13 rated - captures over 90 percent of particles between 1 and 10 microns, including pollen, dust, pet dander, mold spores, smoke, bacteria, and viruses
• Activated carbon layer reduces household odors from cooking, pets, and smoke beyond what mechanical filtration alone provides
• Custom-cut to exact dimensions ordered - actual size 12.5 x 21 x 0.75 inches, built to fit non-standard filter openings
• Reinforced 2-part frame construction provides structural rigidity and supports consistent airflow across the filter face
• Sold as a 6-pack to reduce reorder frequency; 1-inch filters are recommended for replacement every 30 to 90 days depending on environment
• Made in the USA

Compatibility

Designed as a custom-fit replacement for any forced-air furnace or air conditioning system with a filter opening that accepts a 12.5 x 21 x 0.75 inch actual-size filter. Verify the exact opening dimensions before ordering, as custom sizes are not eligible for return.

Installation Notes

Installation is performed by HVAC technicians or qualified homeowners during routine filter maintenance. Power down or set the thermostat to the off position before removing the existing filter to prevent unfiltered air from circulating through the system. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Because this is a custom-cut product, measure the filter slot carefully before ordering - standard sizing tolerances do not apply and the filter is built to the exact dimensions specified at order.
