The synthetic media and plastic frame construction deliver an initial resistance of 0.22 inches w.g. at 375 FPM, rising to 0.48 inches w.g. at 625 FPM, making it a reliable choice for systems that demand consistent airflow performance without rapid pressure-drop buildup. At a maximum airflow of 2,500 CFM and a rated face velocity of 625 FPM, this filter suits medium to large air-handling units where balanced filtration efficiency and low static pressure are both priorities. HVAC technicians and mechanical contractors install this filter as part of routine maintenance or system upgrades.\u003c\/p\u003e\n\u003cp\u003eThis filter fits standard 24 x 24 x 4 inch filter housings found in rooftop units, air-handling units, and built-up systems in commercial office, healthcare, educational, and light-industrial environments. The MERV 13 rating captures fine particulates including dust, pollen, mold spores, and certain airborne droplet nuclei, making it appropriate for facilities with indoor air quality requirements or where occupant health standards apply. Its mini-pleat design maximizes media surface area within the 4-inch depth, supporting longer service intervals compared to standard pleated filters in the same size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 13 filtration rating for high-efficiency particulate capture\u003c\/li\u003e\n  \u003cli\u003eMini-pleat synthetic media maximizes surface area within a 4-inch-depth frame\u003c\/li\u003e\n  \u003cli\u003ePlastic frame construction resists moisture and maintains structural integrity under airflow load\u003c\/li\u003e\n  \u003cli\u003eIntegrated frame design ensures consistent seal within the filter housing\u003c\/li\u003e\n  \u003cli\u003eLow initial resistance of 0.22 inches w.g. at 375 FPM supports efficient system operation\u003c\/li\u003e\n  \u003cli\u003eUL 900 listed for fire safety compliance in air-handling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 24 x 24 x 4 inch filter housings in commercial and residential air-handling units requiring MERV 13 mini-pleat media.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified mechanical contractors. Always shut down the air-handling unit and verify the system is de-energized before opening the filter access panel. Confirm the housing accepts a nominal 24 x 24 x 4 inch filter; actual dimensions are 23.38 x 23.38 x 3.75 inches, which is standard for this nominal size class. Seat the filter firmly so all four edges contact the housing frame, eliminating bypass paths that reduce filtration effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Mini-Pleat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Airflow\u003c\/strong\u003e: 2,500 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Face Velocity\u003c\/strong\u003e: 625 FPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial Resistance at 375 FPM\u003c\/strong\u003e: 0.22 inches w.g.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial Resistance at 500 FPM\u003c\/strong\u003e: 0.34 inches w.g.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial Resistance at 625 FPM\u003c\/strong\u003e: 0.48 inches w.g.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal Resistance\u003c\/strong\u003e: 1.5 inches w.g.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Dimensions (H x W x D)\u003c\/strong\u003e: 24 x 24 x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Dimensions (H x W x D)\u003c\/strong\u003e: 23.38 x 23.38 x 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia Material\u003c\/strong\u003e: Synthetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated Frame\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL 900\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PRO21616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51727961456946,"sku":"PRO21616","price":535.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fcc52b09c5d7fe18d6c31c2a8402a1cd.jpg?v=1788685033","url":"https:\/\/voomisupply.com\/products\/pro-source-pro21616-pleated-air-filter-24x24x4-merv-13","provider":"Voomi Supply","version":"1.0","type":"link"}
