Nordic Pure 11_1/2x21x1ExactCustomM10-6 Merv 10 Filter 6pk

Product Description

The NORDIC PURE 11_1/2x21x1ExactCustomM10-6 is a custom-made, MERV 10 rated pleated air filter designed for residential and light commercial HVAC systems, including central air conditioners and gas or electric furnaces. Measuring 11.5 x 21 x 0.75 inches actual size, this filter ships as a 6-pack and is hand-cut to those exact dimensions. The electrostatically charged filter media captures over 85% of airborne particles in the 3-10 micron range, including dust, pollen, pet dander, and mold spores. Licensed HVAC technicians and qualified service professionals install this filter during routine maintenance. The moisture-resistant beverage board frame holds its shape in high-humidity return air environments.

This filter fits residential and commercial forced-air systems that require a custom 11.5 x 21 x 0.75-inch actual-size filter where standard nominal sizes are unavailable. It is well-suited for households with pets or allergy sufferers who need elevated filtration without restricting airflow. Nordic Pure recommends replacement every 1 to 3 months depending on system use, occupancy, and indoor air quality demands. During active home improvement or renovation, more frequent changes are advised due to increased particulate load on the HVAC system.

Compatibility

Designed as a custom exact-size replacement filter for residential and commercial forced-air HVAC systems requiring an actual filter size of 11.5 x 21 x 0.75 inches. Measure your existing filter before ordering to confirm fit, as nominal and actual sizes frequently differ across manufacturers and system brands.

Installation Notes

Installation is performed by an HVAC technician or qualified service professional as part of routine filter maintenance. Power down or switch the system to the off position at the thermostat before removing the old filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow in the return-air duct or filter cabinet before seating the new filter. Because this is a custom-made product cut to exact dimensions, verify the actual size of the existing filter with a tape measure prior to ordering - custom sizes are not eligible for return.
