Built with a wire-backed synthetic media and a beverage board frame, it delivers 80 to 85 percent particle capture efficiency across a broad range of airborne contaminants. The nominal size is 16 x 25 x 4 inches, with actual dimensions of 15.5 x 24.5 x 3.75 inches. Rated for airflows up to 1,400 CFM at a maximum velocity of 500 feet per minute, this filter handles the demands of standard forced-air systems. Licensed HVAC technicians and facilities maintenance personnel typically install this filter as part of routine preventive maintenance.\u003c\/p\u003e\u003cp\u003eThis filter is suited for use with any forced-air unit that accepts a 16 x 25 x 4-inch filter. It performs well in residential air handlers, light commercial rooftop units, and makeup air systems requiring enhanced filtration. With a MERV 13 rating, it captures fine particulates including dust, pollen, mold spores, and certain bacteria-carrying particles. The initial resistance is 0.34 inches water gauge at 500 feet per minute, rising to a final resistance of 1 inch water gauge at end of service life. The integrated beverage board frame provides structural rigidity during handling and installation. This filter also earns LEED points, making it a practical choice for green building projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 13 rating with 80 to 85 percent particle capture efficiency\u003c\/li\u003e\n\u003cli\u003eWire-backed synthetic pleated media for structural support and consistent airflow\u003c\/li\u003e\n\u003cli\u003eBeverage board frame with integrated construction for easy, secure fitment\u003c\/li\u003e\n\u003cli\u003eRated up to 1,400 CFM and 500 FPM maximum velocity\u003c\/li\u003e\n\u003cli\u003eMaximum operating temperature of 150 degrees F\u003c\/li\u003e\n\u003cli\u003eMeets ASHRAE 52.2 and UL 900 standards; earns LEED points\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with any HVAC unit accepting a nominal 16 x 25 x 4-inch filter slot.

Confirm airflow direction arrow on the filter frame aligns with the direction of airflow into the blower section before fully seating the filter. Inspect the filter slot for frame damage or bypass gaps and seal as needed to maintain rated efficiency. Filter replacement should follow manufacturer service intervals or when final resistance is reached.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 16 x 25 x 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 15.5 x 24.5 x 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParticle Capture Efficiency\u003c\/strong\u003e: 80 to 85 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Airflow\u003c\/strong\u003e: 1,400 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Velocity\u003c\/strong\u003e: 500 FPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial Resistance\u003c\/strong\u003e: 0.34 inches w.g. at 500 FPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal Resistance\u003c\/strong\u003e: 1.0 inch 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\u003eFilter Media Material\u003c\/strong\u003e: Synthetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Beverage Board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Wire-Backed Pleated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Frame\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASHRAE 52.2, UL 900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: PRO21543\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51747623895346,"sku":"PRO21543","price":229.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a1fcdeede7fdc5f19a196a31e3076e4.jpg?v=1788883650","url":"https:\/\/voomisupply.com\/products\/pro-source-pro21543-pleated-air-filter-16x25x4-merv-13","provider":"Voomi Supply","version":"1.0","type":"link"}
