Nordic Pure 18x18x1M8MiniPleat-3 Merv 8 Mini Pleat Filter

Product Description

The NORDIC PURE 18x18x1M8MiniPleat-3 is a MERV 8 mini pleat air filter sold in a 3-pack, designed for use in residential and light commercial HVAC systems. Each filter carries a nominal size of 18x18x1 and an actual size of 17.75 x 17.75 x 0.75 inches, so it seats correctly in standard filter slots that accept this nominal dimension. The polyester filter media is self-supporting and moisture-resistant, and the frame is a two-part beverage board construction that holds its shape in high-humidity conditions. HVAC technicians and facilities maintenance staff install these filters in forced-air furnaces and air handlers where a MERV 8 rating is specified.

These filters suit residential forced-air gas or electric furnaces, heat pumps, and central air conditioning systems that use a 1-inch filter slot rated for nominal 18x18x1 media. The mini pleat design packs 2.5 times more pleats than a standard pleat filter of the same face dimensions, increasing usable media surface area without choking system airflow. The filter captures lint, dust, pollen, pet dander, dust mites, and mold spores at MERV 8 efficiency. Recommended replacement interval is every 2 to 3 months, adjusted for environment and system runtime.

Key Features

• MERV 8 rating, equivalent to MPR 600-800, captures common airborne particles including pollen, pet dander, and mold spores
• 2.5 times more pleats than standard filters increase media surface area and extend filter service life
• Actual size 17.75 x 17.75 x 0.75 inches ensures a precise fit in nominal 18x18x1 filter slots
• Self-supporting polyester media resists mold growth and retains structure without a wire backing
• Two-part moisture-resistant beverage board frame maintains dimensional stability in humid air streams
• Made in the USA

Compatibility

Designed for residential and light commercial forced-air furnaces and air handlers that accept a nominal 18x18x1 filter. Always verify the actual filter slot clearance against the actual dimensions of 17.75 x 17.75 x 0.75 inches before installation, as nominal and actual sizes differ.

Installation Notes

Power down the furnace or air handler at the thermostat and the disconnect before removing the old filter. Note the airflow direction arrow printed on the filter frame and orient the replacement so the arrow points toward the blower. HVAC technicians should confirm the actual slot dimensions match the filter actual size of 17.75 x 17.75 x 0.75 inches, not the nominal 18x18x1 label, to avoid bypass gaps. Dispose of the used filter in a sealed bag to contain captured particulates.
