Nordic Pure 21x21x1ExactCustomM13+C-6 Merv 13 Filter 6pk

Product Description

The NORDIC PURE 21x21x1ExactCustomM13+C-6 is a custom-cut, electrostatically charged pleated air filter rated MERV 13 with an activated carbon layer. It is designed for residential and light commercial forced-air HVAC systems, fitting both air conditioning and gas or electric furnace applications. The filter captures over 90 percent of airborne particles between 1 and 10 microns and 50 to 70 percent of particles between 0.3 and 1 microns. The added carbon layer addresses common household odors. This filter is installed by HVAC technicians or knowledgeable end users during routine maintenance intervals.

This filter is suited for residential forced-air systems where a standard nominal size does not fit the filter rack. The actual dimensions are 21 inches by 21 inches by 0.75 inches, cut to exact measurements rather than the fractional undersizing common in standard filters. It is appropriate for use in single-family homes and small commercial spaces where improved particulate capture and odor reduction are priorities. Six filters are included per box, supporting multiple replacement cycles. Custom sizing makes this filter non-returnable, so the actual slot dimensions should be confirmed with a tape measure before ordering.

Compatibility

Installation Notes

This filter is installed by HVAC technicians or qualified service personnel during routine filter replacement. Power down or set the thermostat to the off position before opening the filter access panel. Confirm airflow direction arrow on the filter frame aligns with the direction of air movement toward the blower. Because this is a custom-cut size, verify the actual filter slot dimensions with a tape measure before installation, as the filter is non-returnable once ordered.
