Nordic Pure 18x20x2M14-3 Merv 14 Air Filter 3 Pack

Product Description

The NORDIC PURE 18x20x2M14-3 is a pleated MERV 14 air filter sold in a 3-pack, designed for use in residential and commercial HVAC systems including forced-air furnaces and central air conditioning units. With a nominal size of 18x20x2 inches and an actual size of 17.5 x 19.5 x 1.75 inches, these filters use electrostatically charged, hypoallergenic, antimicrobial filter media housed in a moisture-resistant beverage board frame. MERV 14 filtration captures particles down to the size of bacteria, virus carriers, smoke, and fine dust - equivalent to an MPR 2800 rating. These filters are manufactured in the USA and rated to the ASHRAE MERV standard.

The 18x20x2M14-3 is suited for residential and light commercial HVAC applications where high-efficiency air filtration is required. Common install scenarios include homes with allergy sufferers, pet owners, or occupants with respiratory sensitivities, as well as commercial units rated to handle MERV 14 and above. Because MERV 14 media carries higher airflow resistance than lower-rated filters, the HVAC system must be rated to support this filtration level. These filters perform well in newer high-efficiency systems designed to handle dense filter media. Replacement is recommended every 1 to 3 months depending on environmental conditions, with more frequent changes needed in high-dust or high-dander environments.

Key Features

• MERV 14 filtration captures airborne dust, pollen, mold spores, pet dander, smoke, smog, dust mite debris, bacteria, and virus carriers
• Electrostatically charged, hypoallergenic, and antimicrobial filter media resists bacterial and mold growth on the filter surface
• Moisture-resistant beverage board frame adds structural durability in humid air stream conditions
• Equivalent to MPR 2800 rating used by other manufacturers
• Actual size 17.5 x 19.5 x 1.75 inches fits nominal 18x20x2 filter slots
• Made in the USA; rated per ASHRAE MERV standard

Compatibility

Designed as an OEM-style replacement for residential and commercial HVAC systems that accept a nominal 18x20x2 inch filter and are rated to operate with MERV 14 or higher filtration media. Verify your system supports MERV 14 before installation, as higher-rated filters increase airflow restriction.

Installation Notes

Installation is typically performed by an HVAC technician or a knowledgeable building owner. Power down the HVAC system at the thermostat or disconnect before replacing the filter. Always install the filter with the airflow arrow on the frame pointing toward the blower, away from the return air side. Confirm the actual slot dimensions match the actual filter size of 17.5 x 19.5 x 1.75 inches before seating the filter, as nominal and actual sizes differ.
