Nordic Pure 18x27x1ExactCustomM7-6 Merv 7 Furnace Filter 6pk

Product Description

The NORDIC PURE 18x27x1ExactCustomM7-6 is a custom-made, pleated AC furnace air filter rated MERV 7, sold in a pack of six. Each filter measures an actual 18 x 27 x 0.75 inches and is built on a moisture-resistant beverage board frame with electrostatically charged filter media. At MERV 7, these filters capture 50 to 70 percent of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores. The media is designed to resist bacterial and mold growth on the filter surface. Licensed HVAC technicians and knowledgeable homeowners install these filters in residential and light commercial forced-air systems.

These filters are suited for residential and commercial HVAC applications where a balance of filtration efficiency and low airflow resistance is needed. The MERV 7 rating is comparable to MPR 600 filters used by other manufacturers and follows the ASHRAE industry standard for air filter efficiency measurement. They are particularly well suited for households with pets or occupants with allergies, and for environments where regular filter replacement every one to three months is part of a routine maintenance schedule. These are custom-cut to the exact nominal size of 18x27x1, making them a direct fit for units requiring that precise dimension.

Installation Notes

HVAC technicians or qualified service personnel should power down the furnace or air handler at the disconnect before replacing the filter. Verify airflow direction arrow on the filter frame aligns with the direction of airflow in the unit before insertion. Nordic Pure recommends replacing this filter every one to three months depending on environment, with more frequent changes in homes with pets or allergy sufferers. Because this is a custom-cut size, confirm the exact slot dimensions with a tape measure prior to ordering.
