Nordic Pure 12_1/2x21x1ExactCustomM12-6 Merv 12 Filter 6pk

Product Description

The NORDIC PURE 12_1/2x21x1ExactCustomM12-6 is a custom-cut, MERV 12 rated pleated air filter designed for residential and light commercial HVAC systems including furnaces and central air conditioners. Supplied in a 6-pack, each filter measures 12.5 x 21 x 0.75 inches actual size. The electrostatically charged filter media captures over 90% of airborne particles between 3 and 10 microns, and 80% to 90% of particles between 1 and 3 microns. The heavy-duty, moisture-resistant beverage board frame is built in a reinforced 2-part construction for added rigidity. This filter is manufactured to order at the exact dimensions specified, making it appropriate for non-standard filter openings that stock sizes cannot serve. Licensed HVAC technicians and facilities maintenance professionals are the primary installers.

This custom exact-size filter fits residential and commercial HVAC applications where the nominal opening requires a 12.5 x 21 x 0.75-inch actual filter. It targets common indoor air quality concerns including lint, dust, pollen, pet dander, mold spores, smoke, bacteria, and virus carriers. MERV 12 performance is comparable to filters rated MPR 1500 to 1900 on proprietary scales. Nordic Pure rates filter efficiency using the ASHRAE MERV standard. Recommended replacement interval is every 1 to 3 months depending on occupancy, pet presence, and allergy sensitivity. Environments with high particulate loads or allergy-sensitive occupants should replace on the shorter end of that range.

• Electrostatically charged pleated media attracts and holds fine airborne particles without restricting airflow
• Reinforced 2-part beverage board frame provides structural support; moisture-resistant construction resists warping
• Custom-cut to exact dimensions (12.5 x 21 x 0.75 inches actual) for non-standard filter openings
• Media does not promote bacterial or mold growth on the filter surface

Compatibility

Custom-made to the exact nominal size 12.5 x 21 x 1 inch filter opening. Actual installed dimensions are 12.5 x 21 x 0.75 inches. Designed as an exact-fit replacement for HVAC systems requiring this specific non-standard filter size. Measure the existing filter or filter slot before ordering - custom sizes are not eligible for returns.

Installation Notes

Filter installation and replacement is typically performed by licensed HVAC technicians or qualified maintenance personnel. Always shut down the HVAC system at the thermostat and disconnect power at the breaker before opening the filter cabinet. Note the airflow direction arrow printed on the filter frame and orient it toward the blower. Because this is a custom-fabricated size, confirm actual slot dimensions match the filter before installation.
