Nordic Pure 18x20x1M7-12 Pleated Air Filter Merv 7

Product Description

The NORDIC PURE 18x20x1M7-12 is a MERV 7 pleated air filter sold in a 12-pack, designed for residential and light commercial HVAC systems including central air conditioners and gas or electric furnaces. The filter measures 17.5 x 19.5 x 0.75 inches actual size with a nominal size of 18x20x1. The electrostatically charged, antimicrobial filter media captures large airborne particles such as household dust, pollen, mold spores, and pet dander on each pass. The heavy-duty beverage board frame is moisture resistant, ensuring structural integrity during normal HVAC operation. Licensed HVAC technicians and knowledgeable homeowners alike install this filter as a direct drop-in replacement during routine maintenance.

This filter is suited for residential forced-air systems and light commercial HVAC applications where MERV 7 filtration is specified. It is rated equivalent to MPR 600 on that alternate scale, making it a straightforward cross-reference for techs working across multiple equipment brands. The 12-pack format is practical for service contractors stocking filters for multiple units or for property managers maintaining several systems on a regular replacement schedule. Nordic Pure recommends changing the filter every one to three months, or more frequently in environments with pets, high dust loads, or ongoing construction activity.

Compatibility

Designed as a direct-fit replacement for residential and light commercial forced-air furnaces and central air conditioning systems that accept a nominal 18x20x1 inch filter. Verify the actual filter slot dimensions against the actual size of 17.5 x 19.5 x 0.75 inches before installation, as nominal and actual sizes differ on nearly all air filters.

Installation Notes

Power down or set the thermostat to OFF before removing the old filter to prevent unfiltered air from bypassing the media during the swap. Note the airflow direction arrow printed on the filter frame and install so the arrow points toward the blower or air handler, not toward the return duct. Dispose of the spent filter in a sealed bag to contain captured particulate. Follow local IAQ maintenance schedules and any applicable codes when servicing commercial HVAC equipment.
