Nordic Pure 18x18x1M13MiniPleat-4 Merv 13 Mini Pleat Filter

Product Description

The NORDIC PURE 18x18x1M13MiniPleat-4 is a MERV 13 mini pleat air filter sold in a 4-pack for residential and light commercial HVAC systems. Each filter carries a nominal size of 18x18x1 with an actual size of 17.75 x 17.75 x 0.75 inches. The mini pleat design packs 2.5 times more pleats than standard filters, increasing usable media surface area without restricting airflow. The synthetic polyester fiber media is self-supporting, and the frame is a two-part moisture-resistant beverage board construction. Filters at this MERV rating capture fine particles including smoke, mold spores, bacteria, and virus carriers, making them suitable for environments with elevated IAQ demands.

These filters are intended for use in residential furnaces, central air handlers, and light commercial HVAC units where a 18x18x1 nominal slot is specified. The MERV 13 rating is equivalent to MPR 1900-2200. Typical applications include single-family homes, condos, and small commercial spaces. Nordic Pure recommends replacing this filter every 2 to 3 months depending on occupancy, pet presence, renovation activity, or elevated dust conditions. The 4-pack format supports a full year of quarterly replacements in a single purchase.

Compatibility

Designed as a direct-fit replacement for residential and light commercial HVAC systems requiring a 18x18x1 nominal filter slot. Always verify the actual filter cavity dimensions against the actual size of 17.75 x 17.75 x 0.75 inches before installation, as nominal and actual sizes frequently differ across equipment brands.

Installation Notes

Filter installation is typically performed by HVAC technicians or qualified service personnel. Power down or set the thermostat to off before opening the filter compartment and removing the old filter. Note the airflow direction arrow on the filter frame and align it with the direction of air movement toward the blower. Dispose of the used filter in a sealed bag to contain captured particulates.
