Nordic Pure 18x24x4M14-2 Pleated Air Filter Merv 14

Product Description

The NORDIC PURE 18x24x4M14-2 is a MERV 14 pleated air filter sold in a 2-pack, designed for forced-air HVAC systems in residential and light commercial applications. The filter media is electrostatically charged synthetic material that captures airborne particulates as small as 0.30 microns. At this rating, the filter removes more than 90% of 1.0-10.0 micron contaminants and up to 85% of 0.30-1.0 micron contaminants. The nominal size is 18x24x4 with an actual size of 17.5 x 23.38 x 3.63 inches. The frame is a moisture-resistant beverage board construction with a bonded metal mesh support grid to maintain pleat integrity under airflow. Installation is handled by HVAC technicians or qualified service professionals.

This filter is intended for HVAC systems rated to handle MERV 14 filtration or higher. High-static filters like this one require adequate system static pressure capacity and are well-suited for newer high-efficiency systems, air handlers with deep-filter housings, and environments where occupant health or air quality standards demand high-performance filtration. Common use cases include households with allergy or asthma concerns, commercial spaces requiring enhanced indoor air quality, and any installation where fiberglass or standard poly filters are insufficient. Filter replacement every 3 to 6 months is recommended to maintain system airflow and filtration efficiency.

Key Features

• MERV 14 rated media captures dust, pollen, mold spores, pet dander, smoke, smog, dust mite debris, and bacteria
• Captures more than 90% of 1.0-10.0 micron particles and up to 85% of 0.30-1.0 micron particles
• Hypoallergenic, antimicrobial, and electrostatic synthetic filter media
• Heavy-duty moisture-resistant beverage board frame with bonded metal mesh pleat support
• Equivalent to MPR 2800 rated filters
• Made in the USA

Compatibility

Designed for forced-air HVAC systems with a 4-inch deep filter housing that supports a nominal 18x24x4 filter slot. System must be rated to handle MERV 14 or higher static resistance. Verify actual filter slot dimensions against the actual size of 17.5 x 23.38 x 3.63 inches before installation.

Installation Notes

MERV 14 filters are typically installed by licensed HVAC technicians. Always shut down the air handler or furnace at the disconnect or thermostat before replacing the filter. Confirm the system blower and ductwork are rated for the increased static pressure associated with MERV 14 filtration before upgrading from a lower-rated filter. Install with the airflow arrow on the frame pointing toward the blower.
