Nordic Pure 18x24x1M13-24 Merv 13 Air Filter 24 Pack

Product Description

The NORDIC PURE 18x24x1M13-24 is a MERV 13 pleated air filter sold in a 24-pack, designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioners. Each filter measures 17.5 x 23.5 x 0.75 inches actual size with a nominal size of 18x24x1 inches. The pleated filter media is electrostatically charged and antimicrobial, trapping lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, smog, and virus carriers. A moisture-resistant beverage board frame supports the media and holds up to typical residential airflow conditions. HVAC technicians and facilities maintenance professionals install this filter as a direct drop-in replacement during routine filter changeouts.

This filter is rated MERV 13, which ASHRAE testing places in the superior filtration category and is equivalent to MPR 2200-2400. It is suited for residential homes, offices, and light commercial environments where occupants have allergy sensitivities, pet exposure, or elevated indoor air quality requirements. Nordic Pure recommends replacement every one to three months, with more frequent changes in high-dust or high-pet environments. The 24-pack format supports stocking multiple units for scheduled preventive maintenance programs.

Compatibility

Designed as a drop-in replacement filter for residential and light commercial forced-air furnaces, central air conditioning systems, and air handlers that accept a nominal 18x24x1-inch filter. Verify the actual filter slot dimensions against the 17.5 x 23.5 x 0.75-inch actual size before installation.

Installation Notes

Filter installation should be performed by a qualified HVAC technician or experienced maintenance professional following equipment manufacturer guidelines. Always shut down the HVAC system at the thermostat and disconnect power at the breaker before opening the filter compartment. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Nominal filter sizes are approximate - always verify the actual slot dimensions match the 17.5 x 23.5 x 0.75-inch actual size to ensure a proper seal and prevent bypass.
