Nordic Pure 20x22x1M7-4 Pleated Merv 7 Air Filter 4 Pack

Product Description

The NORDIC PURE 20x22x1M7-4 is a pleated MERV 7 air filter sold in a 4-pack, designed for residential and light commercial HVAC systems including central air conditioners and gas or electric furnaces. Each filter carries a nominal size of 20x22x1 inches and an actual size of 19.5 x 21.44 x 0.75 inches. The electrostatically charged, hypoallergenic filter media captures large airborne particles on every pass through the system, reducing contaminants that degrade indoor air quality and strain HVAC equipment. The moisture-resistant beverage board frame holds its shape under normal operating conditions. Licensed HVAC technicians and knowledgeable homeowners alike install this filter as a routine maintenance item.

This filter is appropriate for residential homes, apartments, and light commercial spaces where a MERV 7 filtration level is specified. It targets household dust, mold spores, pollen, pet dander, dust mites, and lint. A MERV 7 rating is comparable to the MPR 600 scale used by some other manufacturers, following the ASHRAE industry standard for filter efficiency measurement. Typical replacement interval is every one to three months, though environments with pets, allergy sufferers, or active renovation work may require more frequent changes. The 4-pack format supports stocking multiple filters for consecutive replacement cycles.

Compatibility

Designed as a standard replacement for residential and light commercial HVAC systems that accept a nominal 20x22x1 inch filter. Verify the actual filter slot dimensions against the actual size of 19.5 x 21.44 x 0.75 inches before installation, as nominal and actual sizes differ across HVAC equipment brands.

Installation Notes

Power down the HVAC system at the thermostat or disconnect 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. Inspect the filter housing gasket or seal for gaps that could allow unfiltered air bypass. Follow the equipment manufacturer's recommended replacement schedule, and adhere to applicable local codes when servicing commercial air-handling units.
