Nordic Pure 20x24x1M8-4 Pleated Air Filter Merv 8 4 Pack

Product Description

The NORDIC PURE 20x24x1M8-4 is a pleated MERV 8 air filter sold in a 4-pack, designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioning units. Each filter measures 19.5 x 23.44 x 0.75 inches actual size with a nominal size of 20x24x1. The electrostatically charged filter media captures lint, dust, pollen, bacteria, pet dander, dust mites, mold spores, and other airborne contaminants with each pass. The moisture-resistant beverage board frame provides structural integrity in high-humidity conditions. MERV 8 efficiency is comparable to an MPR 800 rating and follows ASHRAE filtration standards.

This filter is suited for residential homes and light commercial spaces using standard forced-air HVAC equipment. It is commonly installed in return-air filter slots on furnaces and air handlers. The MERV 8 rating makes it a practical choice for households with pets, allergy concerns, or frequent dust accumulation. Nordic Pure recommends changing the filter every 1 to 3 months depending on environmental conditions. Homes with pets or occupants with respiratory sensitivities may require more frequent replacement to maintain airflow and filtration performance.

Installation Notes

Installation should be performed by a qualified HVAC technician or knowledgeable service professional. Power down the furnace or air handler at the disconnect or thermostat before removing and replacing the filter. Note the airflow direction arrow printed on the filter frame and orient it toward the blower. Inspect the filter housing for air bypass gaps that could reduce filtration effectiveness.
