Nordic Pure 18x25x1M13-12 Merv 13 Air Filter 12 Pack

Product Description

The NORDIC PURE 18x25x1M13-12 is a pleated MERV 13 air filter sold in a 12-pack for residential and light commercial HVAC systems. Each filter measures 17.5 x 24.5 x 0.75 inches actual size with a nominal size of 18 x 25 x 1 inch. The electrostatically charged filter media captures lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, smog, and other airborne contaminants. The moisture-resistant beverage board frame holds its shape under normal HVAC airflow conditions. MERV 13 efficiency is equivalent to an MPR rating of 2200-2400. Manufactured in the USA, these filters are rated per ASHRAE standards.

These filters are designed for forced-air furnace and air conditioning systems in homes and light commercial buildings where improved indoor air quality is a priority. They are a practical choice for households with pets, allergy sufferers, or occupants sensitive to airborne particulates. Replacing filters every one to three months is typical under normal conditions; environments with higher dust loads, pets, or renovation activity may require more frequent changes. The 12-pack format reduces reorder frequency and keeps a supply on hand for seasonal maintenance.

Compatibility

Designed as a replacement for nominal 18 x 25 x 1 inch filter slots in residential and light commercial forced-air furnace and air conditioning systems. Verify the actual filter slot dimensions against the actual size of 17.5 x 24.5 x 0.75 inches before installation, as nominal and actual sizes differ across manufacturers.

Installation Notes

Filter replacement is typically performed by HVAC technicians or knowledgeable property owners during routine maintenance. Power down or set the thermostat to off before removing the old filter to prevent unfiltered air from being drawn through the system during the swap. Note the airflow direction arrow printed on the filter frame and orient the new filter so the arrow points toward the blower. Check the filter slot for any gaps or bypass paths that could allow unfiltered air to circumvent the media.
