The filter carries a nominal size of 18x30x1 and an actual size of 17.75 x 29.75 x 0.75 inches, which is the measurement that determines fit. The media is a self-supporting synthetic polyester fiber constructed with 2.5 times more pleats than standard filters, increasing usable surface area while maintaining adequate airflow across the system. The two-part, moisture-resistant beverage board frame holds its shape in high-humidity conditions common to return-air applications. Licensed HVAC technicians and knowledgeable service personnel install these filters as part of routine preventive maintenance schedules.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential homes and commercial spaces where indoor air quality is a priority. It captures lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, and allergens. The MERV 11 rating makes it appropriate for environments with pets, allergy concerns, or elevated particulate loads such as post-renovation cleanups. Nordic Pure recommends replacing the filter every 2 to 3 months depending on the operating environment and system load. Each box contains four filters, making it practical for scheduled quarterly or semi-annual changeout programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 11 rating equivalent to MPR 1000-1200, capturing fine particles including mold spores, smoke, and allergens\u003c\/li\u003e\n  \u003cli\u003e2.5 times more pleats than standard filters for greater particle capture surface area without restricting airflow\u003c\/li\u003e\n  \u003cli\u003eActual size 17.75 x 29.75 x 0.75 inches ensures precise fit in compatible return-air grilles and filter cabinets\u003c\/li\u003e\n  \u003cli\u003eSelf-supporting synthetic polyester fiber media requires no internal wire backing to hold pleat shape\u003c\/li\u003e\n  \u003cli\u003eMoisture-resistant two-part beverage board frame maintains structural integrity in humid return-air environments\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement filter for residential and light-commercial forced-air HVAC systems accepting a nominal 18x30x1 filter.

Always shut down the air handler or furnace at the thermostat and disconnect power at the breaker before removing the old filter.
