The PRO-SOURCE PRO18328 is a synthetic bag-style air filter rated MERV 13, designed for commercial and industrial HVAC air handling units and fan coil systems. With a 6-pocket design, this filter captures 80 to 85 percent of targeted airborne particles, making it appropriate for applications requiring mid-to-high efficiency filtration. It handles airflow up to 2000 CFM at a maximum face velocity of 500 feet per minute. The integrated frame simplifies installation and supports structural integrity under sustained airflow. Nominal dimensions are 24 inches wide by 24 inches high by 22 inches deep, with actual dimensions of 23.375 inches wide by 23.375 inches high by 22 inches deep.
This filter is suited for commercial HVAC systems where improved indoor air quality and particulate control are required. Typical installations include air handling units, rooftop units, and makeup air systems in office buildings, schools, hospitals, and light industrial facilities. The MERV 13 rating makes it a common choice in applications where dust, pollen, mold spores, and fine particulates must be reduced. It is rated for continuous operation at temperatures up to 150 degrees F. A minimum order quantity of 4 units applies to this SKU.
Designed as an OEM-style replacement bag filter for commercial and industrial HVAC air handling units accepting a 24 x 24 x 22 inch nominal bag filter with a 6-pocket configuration.
Installation is typically performed by licensed HVAC technicians or qualified mechanical contractors. Always shut down the air handling unit and confirm zero airflow before replacing filters. Verify that the filter bank housing accepts the nominal 24 x 24 x 22 inch bag filter size and confirm pocket orientation matches the housing design before seating the filter. Dispose of used filters in accordance with local regulations, particularly in applications involving fine particulate capture.
