The NORDIC PURE 18x24x1M8-4 is a pleated MERV 8 air filter designed for residential and light commercial HVAC systems, including forced-air furnaces and central air conditioning units. Sold in a 4-pack, each filter measures 17.5 x 23.5 x 0.75 inches actual size with a nominal size of 18x24x1 inches. The electrostatically charged, hypoallergenic filter media captures lint, dust, pollen, pet dander, dust mites, mold spores, bacteria, and other airborne contaminants. The heavy-duty, moisture-resistant beverage board frame holds its shape under normal airflow conditions. Licensed HVAC technicians and qualified service professionals typically install or recommend these filters as part of routine system maintenance.
This filter is suited for residential homes and light commercial spaces where improved indoor air quality is a priority. It performs well in environments with pets, allergy sufferers, or occupants sensitive to airborne particles. The MERV 8 rating meets ASHRAE standards and is equivalent to an MPR 800 rating used by some other manufacturers. Regular replacement every 1 to 3 months is recommended under normal conditions. Homes with pets or allergy concerns may require more frequent changes. Keeping a fresh filter in place supports proper airflow and helps HVAC equipment run at rated efficiency.
Designed as an OEM-style replacement for residential and light commercial forced-air furnace and central AC systems that accept a nominal 18x24x1 inch air filter. Verify actual slot dimensions against the filter actual size of 17.5 x 23.5 x 0.75 inches before installation, as nominal and actual sizes differ on nearly all air filters.
Always power down the furnace or air handler at the disconnect or thermostat before removing or installing the filter. Note the airflow direction arrow printed on the filter frame and orient it toward the blower, not the return duct. Standard HVAC maintenance practices apply; no special tools are required for filter replacement. Replace every 1 to 3 months, or more frequently in high-particulate or high-occupancy environments.
