Nordic Pure 13x21x1ExactCustomM13+C-12 Merv 13 Filter

Product Description

The NORDIC PURE 13x21x1ExactCustomM13+C-12 is a custom-cut, MERV 13 plus carbon pleated air filter designed for residential and light commercial AC and furnace systems. Built from electrostatically charged synthetic filter media, it captures airborne particulates down to 0.3 microns while the added carbon layer helps neutralize common household odors. The filter measures an exact 13 x 21 x 0.75 inches actual size and ships in a 12-pack. It is installed and serviced by HVAC technicians or knowledgeable DIYers performing routine filter maintenance on forced-air heating and cooling equipment.

This filter is suited for residential forced-air systems where standard nominal sizing does not fit and a custom exact-cut dimension is required. The exact 13 x 21 x 0.75 inch actual size is precision-cut to fit filter slots that cannot accommodate the slight undercut of a standard nominal filter. Custom construction may involve cutting down or combining filter frames and may include reinforcing tape to achieve the specified dimensions. The 12-pack format supports multi-unit properties or extended replacement schedules. Nordic Pure recommends replacing this filter every 30 to 90 days depending on indoor and outdoor air quality conditions.

Custom-cut exact-size replacement filter for forced-air residential and light commercial HVAC systems requiring an actual filter dimension of 13 x 21 x 0.75 inches. Measure the existing filter opening before ordering. Custom sizes are not eligible for returns.

Installation Notes

HVAC technicians or qualified service personnel should confirm the actual filter slot dimensions with a tape measure before installing a custom-size filter. Power down the air handler or furnace at the disconnect before removing the old filter. Install with the airflow arrow on the filter frame pointing toward the blower. Follow local codes and equipment manufacturer guidelines for filter replacement intervals.
