Nordic Pure 12_1/2x21x1ExactCustomM10+C-6 Furnace Filter 6pk

Product Description

The NORDIC PURE 12_1/2x21x1ExactCustomM10+C-6 is a custom-cut, pleated MERV 10 Plus Carbon air filter sized to exact dimensions of 12.5 x 21 x 0.75 inches. It combines a MERV 10 mechanical filtration layer with an activated carbon layer to capture airborne particulates and absorb odors in residential and light commercial HVAC systems. The filter is hand-manufactured in the USA to the specific measurements entered at ordering, using a reinforced 2-part frame construction. HVAC technicians and homeowners installing non-standard duct openings rely on this custom sizing when no standard filter footprint fits the application. At MERV 10 efficiency, it captures over 85 percent of particles in the 3-10 micron range while maintaining low airflow resistance to protect system static pressure.

This filter is designed for forced-air furnace and central air conditioning systems with non-standard filter slot dimensions. It is well suited for residential applications where custom duct configurations, older equipment, or remodeled mechanical rooms prevent the use of standard nominal filter sizes. The 6-pack format supports a multi-month supply, consistent with a 30-90 day replacement interval recommended for 1-inch filters in typical residential environments. Because this product is custom-fabricated to the dimensions ordered, accurate field measurement of the existing filter opening is required before placing an order. Measure the actual filter currently in the slot, not the nominal label size printed on it.

Key Features

• MERV 10 filtration captures over 85 percent of airborne particles between 3-10 microns, including dust, pollen, pet dander, lint, and mold spores
• Activated carbon layer absorbs common household odors alongside mechanical particulate filtration
• Custom-fabricated to exact ordered dimensions of 12.5 x 21 x 0.75 inches - not a nominal cut-down of a standard size
• Reinforced 2-part frame construction provides added rigidity and supports consistent airflow across the filter face
• Sold as a 6-pack with a recommended replacement interval of 30-90 days for 1-inch filters
• Made in the USA

Compatibility

Custom-fabricated to fit forced-air furnace and central AC systems requiring a 12.5 x 21 x 0.75 inch exact-fit filter. Suitable for any HVAC system with a filter slot that accepts this actual dimension. Measure the existing filter before ordering - this size is not returnable.

Installation Notes

Filter installation and replacement on forced-air systems is typically performed by licensed HVAC technicians or qualified service personnel. Before replacing the filter, set the thermostat to the off position to prevent the air handler from drawing in unfiltered air during the swap. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Because this is a custom-cut product, verify the actual slot dimensions with a tape measure before ordering - the actual filter size is typically 1/8 inch or less smaller than the opening on each side.
