Nordic Pure 20x24x1M14-4 Pleated Air Filter Merv 14

Product Description

The NORDIC PURE 20x24x1M14-4 is a MERV 14 pleated air filter sold in a 4-pack, designed for residential and commercial HVAC systems that require high-efficiency particle capture. With a nominal size of 20x24x1 inches and an actual size of 19.5 x 23.44 x 0.75 inches, this filter uses electrostatically charged, hypoallergenic, antimicrobial filter media housed in a moisture-resistant beverage board frame. MERV 14 filtration is rated equivalent to MPR 2800 under the ASHRAE industry standard, making it suitable for high-efficiency systems. Licensed HVAC technicians and experienced service professionals typically handle installation in systems rated for MERV 14 and above.

This filter is intended for residential high-efficiency furnaces, central air conditioning systems, and commercial air handlers where superior indoor air quality is a priority. It is well-suited for environments with occupants who have allergies, asthma, or other respiratory sensitivities, as well as commercial spaces requiring elevated filtration performance. Recommended replacement interval is every 1 to 3 months, though higher-traffic or pet-occupied spaces may require more frequent changes. Because of the elevated filtration density, the HVAC system must be confirmed to support MERV 14 or higher before installation.

Compatibility

Designed as an OEM-style replacement filter for residential and commercial HVAC systems, furnaces, and central air conditioners with a nominal 20x24x1 inch filter slot that are rated to accept MERV 14 or higher filtration. Verify actual slot clearance against the actual dimensions of 19.5 x 23.44 x 0.75 inches before installation.

Installation Notes

Always power down the HVAC system at the thermostat and disconnect electrical supply before replacing the air filter. Confirm the system is rated to handle MERV 14 filters, as higher-density media increases static pressure and may restrict airflow in systems designed for lower MERV ratings. Install the filter with the airflow arrow on the frame pointing toward the blower. Replace every 1 to 3 months or more frequently in high-use or pet-occupied environments.
