Each pack includes 6 filters sized to an actual measurement of 12.75 x 21.5 x 0.75 inches, hand-fabricated to match non-standard filter openings that standard sizes do not cover. The activated carbon layer addresses common household odors while the MERV 7 media captures particles in the 3-10 micron range. A reinforced 2-part frame supports structural integrity during the service life of the filter. Licensed HVAC technicians and knowledgeable DIYers install these as a drop-in replacement where custom dimensions are required.\u003c\/p\u003e\u003cp\u003eThis filter is suited for forced-air furnaces and central air conditioning systems with non-standard filter slots. Typical applications include older residential construction, additions, or retrofitted air handlers where framing does not match nominal filter dimensions. Because the filter is built to the exact dimensions entered at the time of order, it is not interchangeable with standard catalog sizes. Nordic Pure fabricates these filters by cutting down or combining standard filter frames, sometimes with tape reinforcement, depending on the final dimensions. The recommended replacement interval for 1-inch filters is every 30 to 90 days depending on household conditions such as pets, dust levels, and occupancy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 7 media captures 50-70% of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores\u003c\/li\u003e\n\u003cli\u003eActivated carbon layer reduces common household odors at the filter level\u003c\/li\u003e\n\u003cli\u003eCustom-fabricated to the exact nominal size of 13x21.5x1 inches with an actual size of 12.75 x 21.5 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003eReinforced 2-part frame construction provides added durability and supports consistent airflow\u003c\/li\u003e\n\u003cli\u003ePack of 6 filters provides an extended supply for the recommended 30-to-90-day change interval\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a custom OEM-style replacement for residential and light-commercial forced-air furnace and air conditioning systems requiring a non-standard filter size with a nominal dimension of 13x21.5x1 inches.

Power down or shut off the air handler at the disconnect or thermostat before removing the old filter. Confirm airflow direction arrows on the filter frame align with system airflow before seating the filter.
