Nordic Pure 18x25x1M14-24 Merv 14 Air Filter 24 Pack

Product Description

The NORDIC PURE 18x25x1M14-24 is a MERV 14 pleated air filter sold in a 24-pack for residential and light commercial HVAC applications. Each filter measures 17.5 x 24.5 x 0.75 inches actual size with a nominal size of 18 x 25 x 1 inches. The electrostatically charged, hypoallergenic filter media captures airborne dust, pollen, mold spores, pet dander, smoke particles, bacteria, and virus carriers as air passes through the system. The heavy-duty, moisture-resistant beverage board frame holds its shape in demanding HVAC environments. This filter is manufactured in the USA and is installed by HVAC technicians and knowledgeable homeowners in forced-air heating and cooling systems.

MERV 14 filtration is designed for environments that require high-efficiency particle capture, including homes with occupants who have allergies or respiratory sensitivities and commercial spaces that specify above-standard air quality. This rating is equivalent to MPR 2800. Because MERV 14 filters carry a higher airflow resistance than lower-rated filters, the HVAC system must be rated to support MERV 14 or higher. These filters are well-suited for newer, high-efficiency forced-air systems. A filter change interval of every one to three months is recommended, with more frequent changes in homes with pets or high particulate loads.

Compatibility

Designed for forced-air furnace and air conditioning systems rated to handle MERV 14 filters or higher. Verify that the system blower and ductwork can accommodate the increased static pressure of high-MERV media before installation. Always confirm actual filter slot dimensions against the actual size of 17.5 x 24.5 x 0.75 inches rather than relying on the nominal size label alone.

Installation Notes

Installation should be performed with the HVAC system powered down and the thermostat set to off. Confirm airflow direction by checking the arrow printed on the filter frame and align it with the direction of airflow toward the blower. Because nominal and actual filter dimensions differ, measure the existing filter slot before ordering. Replace filters every one to three months or more frequently in high-dust or high-occupancy environments, following the system manufacturer's maintenance guidelines.
