Nordic Pure 18x25x1M13+C-12 Merv 13 Plus Carbon Filter 12 Pack

Product Description

The NORDIC PURE 18x25x1M13+C-12 is a MERV 13 pleated air filter with an integrated activated carbon layer, sold in a 12-pack. Rated at MERV 13, it captures fine particulates including dust mites, pollen, pet dander, mold spores, bacteria, and smoke particles. The activated carbon component adsorbs odorous gases and volatile organic compounds (VOCs), delivering both particulate filtration and odor control in a single filter. The nominal size is 18x25x1 inches with an actual size of 17.5 x 24.5 x 0.75 inches. Licensed HVAC technicians and experienced DIYers install this filter in residential forced-air heating and cooling systems.

This filter is suited for residential HVAC applications where both fine particulate control and odor reduction are priorities. It is an effective choice in homes with pets, smokers, or occupants with allergies. The MERV 13 rating places it equivalent to MPR 2200-2400 filters, making it a high-efficiency option compared to standard fiberglass or poly disposable filters. The electrostatically charged synthetic media and activated carbon panel work together to improve air quality with each pass through the system. Recommended replacement interval is every 30 to 90 days depending on indoor and outdoor conditions, with more frequent changes advised during renovations or high-use periods.

Installation Notes

Filter installation is performed by licensed HVAC technicians or qualified DIYers. Set the thermostat to off and shut down the air handler or furnace before removing the old filter. Note the airflow direction arrow printed on the filter frame and orient the replacement filter accordingly. Measure the actual filter slot dimensions before installation to confirm fit, as the actual size of 17.5 x 24.5 x 0.75 inches differs from the 18x25x1 nominal label.
