The PRO-SOURCE PRO18332 is a synthetic media bag air filter rated MERV 13, designed for commercial and industrial air handling units where high-efficiency particulate capture is required. The filter captures 80 to 85 percent of targeted particles across applicable size ranges, making it a reliable choice for environments with elevated indoor air quality requirements. Eight extended-surface pockets maximize media area and airflow efficiency, supporting up to 2000 CFM at a maximum face velocity of 500 feet per minute. The galvanized steel integrated frame maintains pocket geometry under sustained airflow and resists deformation up to 150 degrees F. Licensed HVAC technicians and mechanical contractors are the primary installers for this class of filter.
The PRO18332 is suited for commercial rooftop units, air handling units, and built-up systems where 24x24 filter banks are specified. The nominal dimensions of 24 inches wide by 24 inches high by 29 inches deep fit standard 24x24 filter housings. Actual dimensions are 23-3/8 inches wide by 23-3/8 inches high by 29 inches deep, which is the correct installed size to confirm against the housing frame. This filter is commonly used in office buildings, schools, healthcare facilities, and light industrial spaces where MERV 13 filtration is called out in mechanical specifications or required by local codes.
Designed as an OEM-style replacement bag filter for commercial air handling units and rooftop units with standard 24x24 nominal filter sections requiring MERV 13 bag-style media.
Installation should be performed by a licensed HVAC technician or qualified mechanical contractor. Always shut down and lock out the air handling unit before removing or installing filter media. Verify the housing frame dimensions against the actual filter dimensions of 23-3/8 inches wide by 23-3/8 inches high before installation. Confirm airflow direction arrows or pocket orientation align with the system airflow direction, and ensure the integrated frame seats fully in the filter rack before returning the unit to service.
