Nordic Pure 18x24x1PolyGreen-4 Merv 6 Air Filter 4-pack

Product Description

The NORDIC PURE 18x24x1PolyGreen-4 is a MERV 6 polyester air filter designed for use in residential and light commercial HVAC systems. Sold in a 4-pack, each filter measures 17.5 x 23.5 x 0.75 inches actual size, fitting nominal 18x24x1 filter slots. The Poly Green construction uses environmentally responsible synthetic media to capture dust, pollen, lint, and other common airborne particles before they circulate through the air handler or furnace. HVAC technicians and facilities maintenance staff install these during routine filter change intervals to maintain system airflow and indoor air quality.

These filters are suited for standard forced-air systems in homes and offices where a MERV 6 filtration level meets the application requirement. The 0.75-inch depth and precise actual dimensions support a snug fit in compatible filter cabinets, reducing bypass around the filter frame. A box of four supports multiple change cycles, making it a practical stocking choice for service technicians or property managers handling several units.

Installation Notes

Filter installation is a routine HVAC maintenance task performed by licensed HVAC technicians or qualified maintenance personnel. Always set the system thermostat to the off position and power down the air handler at the disconnect before removing the old filter. Install the new filter with the airflow arrow on the frame pointing toward the blower, and confirm the filter seats flush against all four sides of the cabinet to prevent bypass. Follow the system manufacturer's recommended change interval or inspect monthly in high-use or dusty environments.
