Nordic Pure 13x21x1ExactCustomM10-6 Merv 10 Filter 6 Pack

Product Description

The NORDIC PURE 13x21x1ExactCustomM10-6 is a custom-cut, MERV 10 pleated air filter designed for residential and light commercial HVAC systems. Measuring 13 x 21 x 0.75 inches actual size, this filter is built on a moisture-resistant beverage board frame and uses electrostatically charged media to capture airborne particulates including lint, dust, pollen, pet dander, mold spores, and smoke particles. At MERV 10, it captures over 85% of particles between 3 and 10 microns. Licensed HVAC technicians and experienced DIYers alike install these filters as a direct replacement in standard 1-inch filter slots. Sold in a 6-pack to support routine replacement schedules.

This filter is suited for residential furnaces, central air conditioning systems, and light commercial air handlers where improved indoor air quality is a priority. The custom dimensions make it appropriate for non-standard filter openings that standard nominal sizes do not cover. Households with pets, allergy sufferers, or occupants sensitive to airborne particulates benefit most from the MERV 10 efficiency rating. Nordic Pure recommends replacing the filter every 1 to 3 months depending on household conditions, with more frequent changes in high-dust or high-dander environments. The 6-pack format supports this replacement cadence.

Compatibility

Custom-made to the exact dimensions of 13 x 21 x 0.75 inches actual size, designed as a direct replacement for 1-inch residential or light commercial HVAC filter slots requiring a non-standard nominal size. Measure your existing filter before ordering; custom sizes are non-returnable.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified service personnel. Always power down the HVAC system at the thermostat and disconnect electrical supply at the disconnect or breaker before accessing the filter compartment. Note the airflow direction arrow printed on the filter frame and orient the filter accordingly when inserting. Because these are custom-cut filters, verify the actual slot dimensions match the 13 x 21 x 0.75 inch actual size prior to installation.
