Nordic Pure 20x20x1M14-4 Pleated Air Filter Merv 14 4 Pack

Product Description

The NORDIC PURE 20x20x1M14-4 is a MERV 14 pleated air filter sold in a 4-pack, designed for residential and light commercial HVAC systems that require high-efficiency particulate filtration. The filter media is electrostatically charged to capture airborne contaminants including dust, pollen, mold spores, pet dander, smoke particles, bacteria, and virus carriers. The frame is constructed from moisture-resistant beverage board, and the media is treated to resist bacterial and mold growth on the filter surface itself. Nominal size is 20x20x1 inches with an actual size of 19.5 x 19.5 x 0.75 inches. These filters are manufactured in the USA and rated equivalent to MPR 2800 under alternative manufacturer rating scales.

This filter is suited for residential furnaces, central air conditioning systems, and commercial air handlers that are rated to accept MERV 14 filtration or higher. High-static-pressure-capable systems and newer high-efficiency units are the appropriate application. MERV 14-rated filters provide a filtration level comparable to what many manufacturers label as HEPA-style performance in HVAC applications. Because MERV 14 media restricts airflow more than lower-rated filters, the HVAC equipment must be rated to handle the increased static pressure. This filter is a strong fit for environments where occupants have allergies, asthma, or other respiratory sensitivities, and for commercial spaces requiring enhanced indoor air quality.

Key Features

• MERV 14 filtration captures dust, pollen, mold spores, pet dander, smoke, bacteria, and virus carriers
• Electrostatically charged, hypoallergenic, and antimicrobial filter media
• Moisture-resistant beverage board frame for structural integrity in humid conditions
• Media does not promote bacterial or mold growth on the filter surface
• Equivalent to MPR 2800 rating used by some other manufacturers
• Made in the USA

Compatibility

Designed for HVAC systems with a nominal 20x20x1 inch filter slot that are rated to support MERV 14 filtration or higher. Verify actual filter slot dimensions against the actual size of 19.5 x 19.5 x 0.75 inches before installation. Not recommended for systems rated below MERV 14 capability due to increased airflow restriction.

Installation Notes

Installation is typically performed by HVAC technicians or knowledgeable building maintenance staff, though filter replacement is a common DIY task. Power down the air handler or furnace before opening the filter compartment and replacing the filter. Always install with the airflow arrow on the filter frame pointing toward the blower, not toward the return air duct. Replace every 1 to 3 months depending on occupancy, pet presence, and indoor air quality demands; environments with high particulate loads or allergy-sensitive occupants may require more frequent changes.
