Nordic Pure 18x30x1M8-4 Pleated Merv 8 Air Filter 4 Pack

Product Description

The NORDIC PURE 18x30x1M8-4 is a pleated MERV 8 air filter sold in a 4-pack, designed for use in residential and light commercial HVAC systems including furnaces and central air conditioning units. Each filter measures 17.75 x 29.75 x 0.75 inches actual size with a nominal size of 18x30x1 inches. The filter media is electrostatically charged to attract and capture airborne particulates, and is constructed with a heavy-duty, moisture-resistant beverage board frame. Licensed HVAC technicians and maintenance professionals install these filters as part of routine preventive maintenance programs.

These filters are suited for residential furnaces, central AC systems, and light commercial air handlers where MERV 8 filtration is specified. MERV 8 efficiency is equivalent to MPR 800 ratings used by some manufacturers. The filter captures lint, dust, pollen, bacteria, pet dander, dust mites, mold spores, and similar airborne contaminants on each pass through the system. Environments with pets, allergy sufferers, or elevated dust loads benefit most from this filtration level. Replacement is recommended every 1 to 3 months depending on site conditions.

Compatibility

Designed as a standard replacement for residential and light commercial furnaces and central air conditioning systems that accept a nominal 18x30x1-inch filter. Verify actual filter slot dimensions against the actual size of 17.75 x 29.75 x 0.75 inches before installation, as nominal and actual sizes differ.

Installation Notes

Filter replacement is a routine task performed by licensed HVAC technicians or qualified maintenance personnel. Always set the system thermostat to the off position and confirm the air handler has stopped before removing the old filter. Install the new filter with the airflow arrow on the frame pointing toward the blower, away from the return air duct. Filters should be inspected monthly and replaced every 1 to 3 months based on system runtime and site conditions.
