Nordic Pure 18x25x1M7-12 Pleated Air Filter Merv 7 12 Pack

Product Description

The NORDIC PURE 18x25x1M7-12 is a MERV 7 pleated air filter sold in a 12-pack, sized for residential and light commercial HVAC systems. Each filter measures 17.5 x 24.5 x 0.75 inches actual size within a nominal 18 x 25 x 1 inch frame. The electrostatically charged, hypoallergenic filter media captures large airborne particles including household dust, pollen, mold spores, and pet dander. A moisture-resistant beverage board frame holds the pleated media securely in place. Licensed HVAC technicians and service pros install these as routine maintenance items in forced-air furnace and air conditioning systems.

These filters are suited for residential and commercial forced-air HVAC applications where a MERV 7 filtration level is specified. They are appropriate for standard furnace filter slots and central air handler cabinets that accept a nominal 18 x 25 x 1 inch filter. MERV 7 performance is rated equivalent to MPR 600 on alternative industry scales. Replacement intervals of one to three months are typical, with more frequent changes recommended in high-dust environments, homes with pets, or during construction and renovation activity.

Installation Notes

Power down the HVAC system at the thermostat and, where practical, at the disconnect or breaker before removing the old filter. Note the airflow direction arrow printed on the filter frame and orient the replacement filter so the arrow points toward the blower. Handle filter media carefully to avoid collapsing the pleats. Follow local mechanical codes and the equipment manufacturer service manual for recommended filter change intervals and access panel procedures.
