Nordic Pure 14x18x1M7-4 Pleated Merv 7 Air Filter 4 Pack

Product Description

The NORDIC PURE 14x18x1M7-4 is a pleated MERV 7 air filter sold in a 4-pack, designed for use in residential and light commercial HVAC systems including forced-air furnaces and central air conditioners. Rated at MERV 7, this filter captures large airborne particles such as household dust, pollen, mold spores, lint, and pet dander on each pass through the air handler. The filter media is electrostatically charged and treated to be hypoallergenic and antimicrobial, resisting bacterial and mold growth on the filter surface itself. The nominal size is 14x18x1 inches with an actual size of 13.5 x 17.5 x 0.75 inches. Licensed HVAC technicians and experienced DIYers install this filter as a scheduled maintenance item.

This filter suits residential homes, apartments, and light commercial spaces where a mid-range particulate filter is appropriate. It is well-suited for environments with pets, allergy sufferers, or occupants sensitive to dust and pollen. MERV 7 performance is comparable to filters rated MPR 600 under other manufacturer rating scales. Nordic Pure recommends changing this filter every 1 to 3 months, with more frequent changes in high-dust environments, during home renovations, or in households with pets or allergy concerns. Regular replacement supports both indoor air quality and HVAC system efficiency by reducing airflow restriction caused by clogged media.

Compatibility

Designed as an OEM-style replacement filter for residential and light commercial forced-air furnaces and central air conditioning systems with a nominal 14x18x1 inch filter slot. Verify the actual slot dimensions against the stated actual size of 13.5 x 17.5 x 0.75 inches before installation, as nominal and actual filter sizes commonly differ across equipment brands.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified DIYers as part of routine system maintenance. Power down the air handler or furnace at the disconnect or thermostat before removing the old filter. Note the airflow direction arrow printed on the filter frame and orient the replacement filter so the arrow points toward the blower. Dispose of the used filter in a sealed bag to avoid redistributing captured particulates.
