Nordic Pure 18x24x1M11MiniPleat-4 Merv 11 Air Filter 4 Pack

Product Description

The NORDIC PURE 18x24x1M11MiniPleat-4 is a MERV 11-rated Tru Mini Pleat air filter sold in a 4-pack, designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioning units. The filter media is self-supporting synthetic polyester fiber housed in a heavy-duty, moisture-resistant two-part beverage board frame. At a nominal size of 18x24x1 and an actual size of 17.5 x 23.5 x 0.75 inches, these filters deliver advanced particle capture while maintaining adequate airflow across the system. Licensed HVAC technicians and knowledgeable service personnel install these as routine maintenance replacements.

This filter suits residential homes and commercial spaces requiring reliable mid-range filtration. The mini-pleat design features 2.5 times more pleats than standard flat-panel or basic pleated filters, increasing usable media surface area within the same nominal footprint. Captured contaminants include lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, and allergens. Nordic Pure recommends replacing these filters every 2 to 3 months depending on environmental conditions such as renovation activity, pet occupancy, or high-dust environments.

Compatibility

Designed as an OEM-style replacement filter for residential and light commercial forced-air HVAC systems that accept a nominal 18x24x1 inch filter. Always verify against the actual size of 17.5 x 23.5 x 0.75 inches before installation, as nominal and actual dimensions differ across equipment manufacturers.

Installation Notes

Power down the furnace or air handler at the thermostat or disconnect before replacing the filter. Confirm airflow direction arrow on the filter frame aligns with the direction of air movement toward the blower. Nominal filter sizes are not standardized across all equipment - always measure the existing filter slot and compare to the actual size of 17.5 x 23.5 x 0.75 inches before ordering. Dispose of the used filter in a sealed bag to prevent releasing captured particulates.
