Nordic Pure 18x20x1M14-4 Merv 14 Air Filter 4 Pack

Product Description

The NORDIC PURE 18x20x1M14-4 is a MERV 14 pleated air filter sold in a 4-pack, designed for forced-air HVAC systems in residential and commercial applications. Rated MERV 14, these filters capture fine airborne particles including dust, pollen, mold spores, pet dander, smoke, bacteria, dust mite debris, and smog. The filter media is electrostatically charged to improve particle capture and is treated with an antimicrobial compound that resists mold and bacteria growth on the filter surface. The heavy-duty beverage board frame is moisture resistant. Nominal size is 18x20x1 inches with an actual size of 17.5 x 19.5 x 0.75 inches.

These filters are suited for residential homes and commercial environments where occupants have allergies, asthma, or other respiratory sensitivities. They are also appropriate for facilities that require high-efficiency filtration at the MERV 14 level and above. Because MERV 14 filters restrict airflow more than lower-rated filters, the HVAC system must be rated to handle this filtration level. They are well matched to newer high-efficiency systems designed for dense filter media. Filter replacement every 1 to 3 months is recommended, with more frequent changes advised in homes with pets or high dust loads.

Key Features

Compatibility

Designed as a MERV 14 replacement air filter for forced-air furnace and air conditioning systems with nominal 18x20x1 inch filter slots. The HVAC system must support MERV 14 or higher rated filters. Verify actual filter opening dimensions against the actual size of 17.5 x 19.5 x 0.75 inches before installation.

Installation Notes

Air filter replacement is performed by HVAC technicians or qualified service professionals. Power down the HVAC system at the thermostat or disconnect before opening the filter access panel. Install the filter with the airflow arrow on the frame pointing toward the blower motor, not toward the return air duct. Confirm the system blower and ductwork are rated for MERV 14 media before installation, as undersized or older systems may experience reduced airflow with high-efficiency filters.
