Nordic Pure 18x36x1CustomM12+C-6 Merv 12 Carbon Filter

Product Description

The NORDIC PURE 18x36x1CustomM12+C-6 is a custom-cut, electrostatically charged pleated air filter rated MERV 12 with an activated carbon layer, designed for residential and light-commercial AC and furnace systems. It measures 17.5 x 35.5 x 0.75 inches actual size and ships in a 6-pack. The electrostatic synthetic media captures over 90% of airborne particles between 3 and 10 microns, and 80% to 90% of particles between 1 and 3 microns. The integrated carbon layer adsorbs odors alongside particulate contaminants. Licensed HVAC technicians and experienced installers handle this filter as a direct drop-in replacement during routine maintenance calls.

This filter is suited for residential and light-commercial HVAC systems requiring a non-standard 18x36x1 nominal slot. Custom sizes are fabricated by cutting down or combining standard filter frames, sometimes joined with tape, to meet the exact nominal dimension. Because this is a custom-manufactured product, it is non-returnable. Nordic Pure recommends replacing this filter every 30 to 90 days depending on indoor and outdoor air quality conditions, occupancy, and the presence of pets or allergy sufferers in the space.

Compatibility

Custom-fabricated to fit HVAC systems with a nominal 18x36x1 filter slot. Actual dimensions are 17.5 x 35.5 x 0.75 inches. Measure the existing filter opening before ordering; custom sizes are not eligible for returns.

Installation Notes

Installation is performed by a licensed HVAC technician or qualified installer. Power down the air handler or furnace at the disconnect or breaker before removing the old filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Because this is a custom size, verify the actual opening dimensions with a tape measure before installation to confirm proper fit and prevent air bypass.
