Nordic Pure 18x24x4M14-6 Pleated Air Filter Merv 14 6 Pack

Product Description

The NORDIC PURE 18x24x4M14-6 is a MERV 14 pleated air filter sold in a 6-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 including dust, pollen, mold spores, pet dander, smoke, smog, bacteria, and virus carriers. Each filter captures 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. HVAC technicians, building engineers, and knowledgeable DIYers install these filters during routine preventive maintenance.

This filter is suited for residential homes, offices, and light commercial spaces where indoor air quality is a priority, particularly for occupants with allergies, asthma, or other respiratory sensitivities. Because MERV 14 filtration creates higher static pressure than lower-rated filters, the HVAC system must be rated to support MERV 14 or above before installation. These filters are also compatible with newer high-efficiency systems that are engineered for HEPA-level media. Nordic Pure recommends replacing the filter every 3 to 6 months under normal operating conditions, with more frequent changes during construction, renovation, or high-dust periods.

Compatibility

Designed as a drop-in replacement filter for forced-air furnace and air conditioning systems with a nominal 18x24x4 inch filter slot rated to handle MERV 14 filtration or higher. Always verify the actual filter opening dimensions against the actual size of 17.5 x 23.38 x 3.63 inches before installation.

Installation Notes

Installation is performed by HVAC technicians or qualified maintenance personnel. Always shut down the furnace or air handler at the thermostat and disconnect power at the disconnect switch or breaker before removing the existing filter. Confirm airflow direction on the new filter and align the directional arrow on the frame with the direction of airflow toward the blower. Because MERV 14 media restricts airflow more than lower-rated filters, verify the system is rated for MERV 14 or above before installation to avoid strain on the blower motor.
