Nordic Pure 19x21x1ExactCustomM12-6 Merv 12 Filter 6pk

Product Description

The NORDIC PURE 19x21x1ExactCustomM12-6 is a custom-cut, MERV 12 pleated air filter designed for residential and light commercial HVAC systems. Measuring 19 x 21 x 0.75 inches actual size, this filter is electrostatically charged to capture airborne particles including lint, dust, pollen, pet dander, mold spores, smoke particles, bacteria, and virus carriers. MERV 12 efficiency means capture rates above 90% for particles between 3 and 10 microns, and 80% to 90% for particles between 1 and 3 microns. The frame is constructed from moisture-resistant beverage board reinforced with a 2-part design for added durability. Each order contains 6 filters. Installation is straightforward for licensed HVAC technicians and knowledgeable DIYers alike.

This filter fits residential and commercial forced-air systems where a 19 x 21 x 1 nominal slot is required. It is manufactured to exact dimensions, making it suitable for non-standard or custom filter openings that standard off-the-shelf sizes cannot fill. Custom construction may involve cutting down or combining filter frames and may include tape reinforcement depending on the final dimensions. The filter media will not promote bacterial or mold growth on the filter surface. Replacement is recommended every 1 to 3 months, or more frequently in homes with pets or occupants with allergy sensitivities.

Compatibility

Designed as a custom exact-fit replacement for residential and light commercial forced-air furnace and air conditioning systems requiring a 19 x 21 x 1 nominal filter slot with an actual size of 19 x 21 x 0.75 inches. Because this is a custom-made product, confirm actual slot dimensions with a tape measure before ordering.

Installation Notes

HVAC technicians and qualified service personnel should power down the air handler or furnace before replacing the filter. Verify airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Custom-sized filters are cut to exact dimensions and are not returnable; measure the existing filter or the filter slot carefully before placing an order. Follow local codes and ASHRAE guidelines for filter maintenance intervals in commercial applications.
