Pro-source PRO11748 Polyester Air Filter Pad 20x20x0.5 Merv 7

Product Description

The PRO-SOURCE PRO11748 is a polyester air filter media pad rated MERV 7, designed for use in a wide range of HVAC air handling applications. Measuring 20 inches high by 20 inches wide by 0.5 inches deep, this flat media pad delivers 833 CFM of rated airflow at a maximum face velocity of 300 feet per minute (FPM). It carries a 25% particle capture efficiency and 84% arrestance efficiency, making it effective at trapping larger airborne particles such as lint, dust fibers, and coarse debris. The pad features a dry tackifier treatment that helps retain captured particles within the media. HVAC technicians and service professionals install this pad as a primary or pre-filter stage in commercial and residential air handling units.

This media pad is suited for installation in HVAC air handling units, fan coil units, and equipment that accepts roll or cut-to-fit media. Its 20 by 20 inch cut dimensions and 0.5 inch depth make it a common fit for standard filter frames, media racks, and side-access air handlers where thin flat-pad filtration is specified. The pad is rated for continuous use up to 180 degrees F, allowing placement in applications with elevated operating temperatures. It is compatible with any unit that accepts media pad filtration in the corresponding cut size.

Compatibility

Designed as a cut-to-fit or frame-mounted media pad replacement for any air handling unit or filter rack that accepts a 20 by 20 by 0.5 inch flat polyester media pad.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified service professional. Always shut down the air handling unit and confirm power is off at the disconnect before removing or inserting filter media. Ensure the media pad is seated flush and fully within the filter frame or holding rack to prevent bypass airflow around the edges. Inspect the filter frame for damage or excessive dust buildup at each service interval.
