Nordic Pure 18x18x1M7-12 Pleated Air Filter Merv 7

Product Description

The NORDIC PURE 18x18x1M7-12 is a pleated MERV 7 air filter sold in a 12-pack, designed for use in residential and light commercial HVAC systems including forced-air furnaces and central air conditioning units. Each filter measures 17.75 x 17.75 x 0.75 inches actual size with a nominal size of 18x18x1. The filter media is electrostatically charged and carries an antimicrobial, hypoallergenic treatment. The frame is constructed from heavy-duty, moisture-resistant beverage board. At MERV 7, this filter targets large airborne particles including household dust, lint, pollen, mold spores, and pet dander while maintaining adequate airflow for most residential systems.

This filter is suited for residential and light commercial forced-air systems where regular filter changes are part of a standard maintenance schedule. Typical applications include gas and electric furnaces, heat pumps, and split-system air conditioners with standard 1-inch filter tracks. Nordic Pure recommends replacing this filter every 1 to 3 months depending on occupancy, pet presence, and local air quality. Homes with allergy sufferers or pets may require more frequent replacement. The 12-pack format supports a full year or more of scheduled changes on a single order.

Compatibility

Designed as a direct-fit replacement for residential and light commercial HVAC systems using a nominal 18x18x1 inch filter slot. Verify the actual filter cavity dimensions before installation, as nominal and actual sizes differ across equipment brands.

Installation Notes

A licensed HVAC technician or qualified service professional should verify filter sizing against the actual filter cabinet opening before installation. Power down the HVAC system at the thermostat or disconnect before opening the filter access panel. Install the filter with the airflow arrow on the frame pointing toward the blower. Never operate the system without a properly seated filter, as an unfiltered or bypassing filter can allow debris to accumulate on the evaporator coil and blower wheel.
