Nordic Pure 18x20x1M13+C-4 Merv 13 Plus Carbon Filter 4 Pack

Product Description

The NORDIC PURE 18x20x1M13+C-4 is a MERV 13 pleated air filter with activated carbon media, sold in a 4-pack. Nominal size is 18x20x1 inches with an actual size of 17.5 x 19.5 x 0.75 inches. The filter combines electrostatically charged synthetic media with a flat activated carbon panel that captures fine particulates and adsorbs odorous gases, vapors, and volatile organic compounds (VOCs). A metal mesh support grid bonds to the pleats for structural integrity. The moisture-resistant beverage board frame handles normal HVAC operating conditions. Licensed HVAC technicians and facilities maintenance staff typically install this filter in residential and light commercial forced-air systems.

This filter suits residential furnaces, air handlers, and central air conditioning systems where both particulate removal and odor control are priorities. It is particularly well-suited for environments with pets, smokers, or recent home renovation activity where VOC and particulate loads are elevated. The antimicrobial filter media resists bacterial and mold growth within the media itself. NORDIC PURE rates this filter as equivalent to MPR 2200-2400 products. Recommended replacement interval is every 30 to 90 days depending on indoor air quality conditions and usage load.

Compatibility

Designed as a standard 18x20x1 nominal replacement for residential and light commercial forced-air furnace, air handler, and central AC systems that accept 1-inch pleated panel filters. Verify fit against the actual size of 17.5 x 19.5 x 0.75 inches before installation.

Installation Notes

Power down the furnace or air handler at the disconnect or thermostat before removing the existing filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Because nominal and actual filter dimensions differ, measure the filter slot before ordering to confirm the actual size of 17.5 x 19.5 x 0.75 inches is the correct fit. Replace every 30 to 90 days or more frequently in high-dust or high-odor environments.
