Pro-source PRO11738 Polyester Air Filter Pad 20x20x1 Merv 7

Product Description

The PRO-SOURCE PRO11738 is a polyester air filter media pad rated MERV 7, designed for use in commercial and residential HVAC air filtration systems as a prefilter or primary filter media. Measuring 20 inches high by 20 inches wide by 1 inch deep, this pad delivers 833 CFM airflow capacity at a maximum face velocity of 300 feet per minute. It achieves 85 percent arrestance efficiency and 25 percent particle capture efficiency, making it effective for trapping lint, dust, and larger airborne particles. A dry tackifier treatment enhances particle retention without adhesive mess. Licensed HVAC technicians and filter maintenance professionals are the typical installers.

This filter media pad is suited for a wide range of air handling applications including commercial air handlers, makeup air units, fan coil units, and residential forced-air systems. Its 20 x 20 x 1 inch form factor fits standard filter housings and media frames of that dimension. The pad withstands operating temperatures up to 180 degrees F, allowing use in higher-temperature supply-air environments. It is rated for use with any unit, giving technicians flexibility across a broad range of equipment types and filter bank configurations.

Compatibility

Designed for use with any unit requiring a 20 x 20 x 1 inch filter media pad; compatible across residential and commercial HVAC filter housings, air handlers, and media frames accepting this standard pad size.

Installation Notes

Installation should be performed by a qualified HVAC technician or trained maintenance professional. Always power down the air handling unit and verify the system is de-energized before accessing the filter compartment. Confirm airflow direction markings on the housing and seat the pad flat against the frame to prevent bypass. Replace the pad when final resistance reaches 1.0 inch w.g. as indicated by a differential pressure gauge or per scheduled maintenance intervals.
