Nordic Pure 18x30x1M7-3 Pleated Merv 7 Air Filter 3 Pack

Product Description

The NORDIC PURE 18x30x1M7-3 is a pleated MERV 7 air filter sold in a 3-pack, designed for use in residential and light commercial HVAC systems including forced-air furnaces and central air conditioners. The filter media is electrostatically charged and antimicrobial, capturing large airborne particles such as household dust, pollen, mold spores, and pet dander on each air pass. The actual dimensions are 17.75 x 29.75 x 0.75 inches, fitting nominal 18x30x1 filter slots. The moisture-resistant beverage board frame maintains structural integrity in high-humidity airstreams. MERV 7 performance is equivalent to an MPR 600 rating. Installation and replacement are handled by HVAC technicians and knowledgeable DIYers alike.

This filter is suited for residential forced-air systems and light commercial HVAC applications where a balance of airflow and particle capture is required. It is appropriate for environments with pets, allergy sufferers, or elevated dust loads. Nordic Pure recommends replacing this filter every 1 to 3 months depending on occupancy, pet presence, and indoor air quality demands. During renovation or construction activity, more frequent changes are advisable to protect equipment and maintain indoor air quality.

Compatibility

Designed as a direct replacement for nominal 18x30x1 filter slots in residential and light commercial forced-air furnaces and central air conditioning systems. Verify the actual filter opening measures approximately 17.75 x 29.75 x 0.75 inches before installation, as nominal and actual filter dimensions differ across equipment brands.

Installation Notes

Filter replacement is a standard HVAC maintenance task performed by licensed technicians or qualified DIYers. Always set the system thermostat to the off position and confirm the air handler has stopped before removing the existing filter. Insert the new filter with the airflow direction arrow on the frame pointing toward the blower. Follow local codes and equipment manufacturer guidelines for recommended filter change intervals.
