Nordic Pure 25x25x1M14-4 Pleated Air Filter Merv 14 4 Pack

Product Description

The NORDIC PURE 25x25x1M14-4 is a pleated MERV 14 air filter sold in a 4-pack, designed for forced-air HVAC systems in residential and commercial applications. Each filter measures 24.5 x 24.5 x 0.75 inches actual size with a nominal size of 25x25x1. The electrostatically charged, hypoallergenic filter media captures airborne dust, pollen, mold spores, pet dander, smoke particles, bacteria, smog, and dust mite debris. The heavy-duty, moisture-resistant beverage board frame holds its shape under normal system static pressure. MERV 14 efficiency is equivalent to MPR 2800 on competing rating scales. Licensed HVAC technicians and knowledgeable homeowners install these filters in compatible high-efficiency systems.

These filters are suited for residential homes and light commercial spaces where occupants have allergy sensitivities, asthma, or other respiratory concerns, or where indoor air quality standards are elevated. Because MERV 14 filtration increases air flow resistance compared to lower-rated filters, the HVAC system must be rated to handle MERV 14 or higher. Newer high-efficiency systems designed for HEPA-grade filtration are typical candidates. Filter replacement every 1 to 3 months is recommended under normal conditions, with more frequent changes in high-traffic, pet-occupied, or construction-adjacent environments.

Compatibility

Designed as a MERV 14 pleated replacement filter for residential and commercial forced-air HVAC systems with a nominal 25x25x1 inch filter slot. System must be rated to support MERV 14 or higher filtration; verify equipment specifications before installation.

Installation Notes

Installation is performed by a licensed HVAC technician or a qualified equipment owner following the system manufacturer guidelines. Power down or set the thermostat to off before removing the existing filter to prevent unfiltered air from bypassing the media during changeout. Confirm the actual slot dimensions match the actual filter size of 24.5 x 24.5 x 0.75 inches before installation, as nominal and actual sizes differ. Replace every 1 to 3 months or more frequently in high-load environments.
