Nordic Pure 19x21x1CustomM13-6 Merv 13 Furnace Filter 6pk

Product Description

The NORDIC PURE 19x21x1CustomM13-6 is a custom-cut, MERV 13 rated pleated air filter designed for residential and light commercial HVAC systems. Rated at MERV 13, this filter captures over 90% of airborne particles between 1 and 10 microns, and 50% to 70% of particles between 0.3 and 1 micron, including dust, pollen, pet dander, mold spores, smoke, bacteria, and virus carriers. The filter media is electrostatically charged to attract and hold fine particles. The frame is constructed from a moisture-resistant beverage board and features a reinforced 2-part design for added structural integrity. This 6-pack is hand-fabricated to the exact nominal dimensions of 19x21x1, with an actual size of 18.5 x 20.5 x 0.75 inches.

This filter is suited for residential forced-air furnaces and central air conditioning systems where improved indoor air quality is a priority. It is a strong choice for households with pets, allergy sufferers, or anyone in environments with elevated airborne particulate levels. The MERV 13 rating is comparable to MPR 2200-2400 on competing rating scales, making it a high-efficiency option for standard 1-inch filter applications. Nordic Pure rates its filters per ASHRAE industry standards. Replacement every 1 to 3 months is recommended under normal operating conditions, with more frequent changes advised in high-dust or high-dander environments.

Actual installed dimensions are 18.5 x 20.5 x 0.75 inches. Measure your existing filter before ordering, as custom sizes are non-returnable.

Installation Notes

Installation of replacement air filters is typically performed by HVAC technicians or qualified homeowners. Power down or switch the system to off at the thermostat before removing the old filter. Note the airflow direction arrow printed on the filter frame and orient the new filter accordingly. Nordic Pure recommends replacement every 1 to 3 months; environments with pets or allergy concerns may require more frequent service intervals.
