The NORDIC PURE 18x18x1M11MiniPleat-3 is a MERV 11 Tru Mini Pleat air filter sold in a 3-pack for residential and light commercial HVAC systems. The filter uses a self-supporting synthetic polyester fiber media rated at MERV 11, equivalent to MPR 1000-1200, to capture lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, and allergens. The pleated media design incorporates 2.5 times more pleats than a standard filter, increasing surface area for higher particle capture efficiency while maintaining adequate airflow. The frame is a heavy-duty two-part, moisture-resistant beverage board construction. Nominal size is 18x18x1; actual size is 17.75 x 17.75 x 0.75 inches. Licensed HVAC technicians and knowledgeable DIYers install this filter as a routine maintenance item.
This filter is suited for residential forced-air furnace and central AC systems as well as light commercial air handlers where a nominal 18x18x1 filter slot is specified. The MERV 11 rating makes it appropriate for environments with pets, allergy concerns, or elevated dust loads. Nordic Pure recommends replacing the filter every 2 to 3 months depending on operating conditions, though higher-dust environments such as renovation sites may require more frequent changes. Each box contains 3 filters, reducing per-unit cost and extending the maintenance interval between orders.
Designed as an OEM-style replacement filter for residential and light commercial HVAC systems that accept a nominal 18x18x1 air filter. Always verify the actual filter slot dimensions against the actual size of 17.75 x 17.75 x 0.75 inches before installation, as nominal and actual sizes often differ across equipment brands.
This filter is installed by HVAC technicians or knowledgeable DIYers as part of routine preventive maintenance. Always shut down the air handler or furnace at the disconnect or thermostat before removing or installing the filter. Confirm airflow direction markings on the filter frame align with the system airflow arrow before seating the filter. Inspect the filter slot and surrounding cabinet seal for bypass gaps that would allow unfiltered air to enter the system.
