Nordic Pure 18x20x1M10-4 Pleated Air Filter Merv 10

Product Description

The NORDIC PURE 18x20x1M10-4 is a MERV 10 pleated air filter sold in a 4-pack, designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioners. Each filter measures 17.5 x 19.5 x 0.75 inches actual size with a nominal size of 18 x 20 x 1 inches. The electrostatically charged, hypoallergenic filter media captures pollen, dust, pet dander, mold spores, bacteria, smoke particles, virus carriers, and other airborne contaminants. The frame is constructed from moisture-resistant beverage board for structural integrity in high-humidity conditions. MERV 10 performance is equivalent to MPR 1000 on competing rating scales.

This filter is suited for residential homes and commercial office environments where moderate-efficiency air filtration is required. It is particularly well-suited for occupants with mild allergies or households with pets. Recommended replacement interval is every 1 to 3 months, though higher-dust environments or homes with multiple pets may require more frequent changes. Regular replacement supports better indoor air quality and helps maintain HVAC system efficiency. The 4-pack format reduces reorder frequency for maintenance schedules.

Compatibility

Designed as a direct-fit replacement for standard 18 x 20 x 1 inch nominal filter slots in residential and light commercial forced-air furnaces and central air conditioning systems. Actual dimensions are 17.5 x 19.5 x 0.75 inches - verify the actual slot measurement before ordering, as nominal and actual filter sizes frequently differ across equipment brands.

Installation Notes

Air filters in this size class are typically serviced by HVAC technicians or qualified DIYers during routine maintenance. Before replacing the filter, shut down the air handler or furnace at the thermostat and, for added safety, at the disconnect switch. Note the airflow direction arrow printed on the filter frame and install with the arrow pointing toward the blower. Do not operate the system without a filter seated in the rack, as unfiltered air can deposit debris on the evaporator coil and blower wheel.
