Nordic Pure 18x20x2M7-3 Pleated Air Filter Merv 7 3 Pack

Product Description

The NORDIC PURE 18x20x2M7-3 is a MERV 7 pleated air filter sold in a 3-pack, designed for use in residential and light commercial HVAC systems including central air conditioners and gas or electric furnaces. The filter media is electrostatically charged and antimicrobial, capturing large airborne particles such as household dust, pollen, mold spores, and pet dander on each pass. The frame is constructed from moisture-resistant beverage board for rigidity and longevity. With a nominal size of 18x20x2 and an actual size of 17.5 x 19.5 x 1.75 inches, this filter ships as a 3-pack and is rated equivalent to MPR 600. Licensed HVAC technicians and homeowners with basic mechanical aptitude handle routine filter replacement.

This filter is suited for forced-air residential furnaces, central air conditioning systems, and light commercial air handlers where a MERV 7 rating provides a practical balance between airflow and particle capture. It is an effective upgrade over standard fiberglass filters for households with pets, allergy sufferers, or environments with elevated dust loads. Nordic Pure recommends replacing the filter every 1 to 3 months depending on occupancy, pet presence, and overall indoor air quality demands. During active home renovation or construction, more frequent changes are advisable to protect equipment and maintain air quality.

Installation Notes

Filter replacement is a standard HVAC maintenance task performed by licensed HVAC technicians or qualified building maintenance personnel. Always shut down the furnace or air handler at the thermostat and disconnect power at the breaker before removing the existing filter. Install the replacement filter with the airflow arrow on the frame pointing toward the blower motor and away from the return air duct. Dispose of the used filter promptly and inspect the filter cabinet for debris before closing.
