Nordic Pure Merv 13 Custom Furnace Filter 11.25x19.25x0.75 6 Pack

Product Description

The NORDIC PURE 11_1/4x19_1/4x1ExactCustomM13-6 is a custom-cut, MERV 13 pleated air filter designed for residential and light-commercial HVAC systems including forced-air furnaces and central air conditioners. Rated MERV 13 per ASHRAE standards, it captures over 90% of airborne particles between 1 and 10 microns and 50% to 70% of particles between 0.3 and 1 micron. The electrostatically charged filter media targets lint, dust, pollen, pet dander, mold spores, smoke, bacteria, and virus carriers. The actual size is 11.25 x 19.25 x 0.75 inches. This six-pack is hand-fabricated to those exact dimensions and is not a stock nominal size.

This filter suits residential homes and office environments where higher-efficiency filtration is needed without sacrificing airflow. It installs in standard filter slots on gas furnaces, heat pumps, and central AC air handlers. The MERV 13 rating makes it appropriate for households with allergy sufferers, pet owners, or anyone requiring finer particulate control. Filter replacement every one to three months is typical, though high-occupancy or pet-heavy environments may require more frequent changes. Because this is a custom-fabricated size, technicians should verify the exact slot dimensions before ordering.

Compatibility

Designed as a custom exact-size replacement for residential and commercial forced-air HVAC systems requiring a filter with actual dimensions of 11.25 x 19.25 x 0.75 inches. Verify slot dimensions with a tape measure before ordering, as nominal and actual filter sizes frequently differ. This custom size is not interchangeable with standard nominal stock filters.

Installation Notes

HVAC technicians and qualified installers should shut down the furnace or air handler at the thermostat and disconnect power at the breaker before servicing the filter compartment. Confirm airflow direction arrows on the filter frame align with the direction of airflow into the blower. Because this is a custom-fabricated product, measure the filter slot to the nearest fraction of an inch before ordering - returns are not accepted on custom sizes. Replace on a one- to three-month schedule, or more frequently in high-particulate environments.
