With a nominal size of 18x24x1 inches and an actual size of 17.5 x 23.5 x 0.75 inches, this filter fits standard 1-inch filter slots found in forced-air furnaces, air handlers, and central air conditioning systems. At MERV 11, it captures a broad range of airborne particles including dust, pollen, mold spores, pet dander, and fine dust from household activity. HVAC technicians and service pros install these as part of routine preventive maintenance or seasonal filter changes.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential split systems, packaged units, and light commercial air handlers that accept a nominal 18x24x1 filter. It performs well in environments where air quality concerns are moderate to high, such as homes with pets, allergy-sensitive occupants, or moderate dust loads. The pleated media design increases surface area compared to fiberglass panel filters, supporting longer service intervals between changes while maintaining airflow efficiency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 11 filtration rating captures particles down to fine dust, pollen, mold spores, and pet dander\u003c\/li\u003e\n  \u003cli\u003ePleated media construction maximizes filter surface area for improved dust-holding capacity\u003c\/li\u003e\n  \u003cli\u003eNominal size 18x24x1 inches fits standard 1-inch residential and light commercial filter slots\u003c\/li\u003e\n  \u003cli\u003eActual size 17.5 x 23.5 x 0.75 inches for proper fit without forcing or gapping\u003c\/li\u003e\n  \u003cli\u003eSold in a quantity of 10 per order, supporting multi-unit restocking or service fleet use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement pleated air filter for residential and light commercial forced-air HVAC systems accepting a nominal 18x24x1 inch, 1-inch-thick filter slot.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFilter installation and replacement is typically performed by HVAC technicians or qualified service professionals.
