The PRO-SOURCE PRO78213 is a 5-pocket synthetic bag air filter rated MERV 11, designed for commercial and industrial HVAC air handling units and fan-coil systems where higher-efficiency filtration is required. At a nominal size of 20 inches wide by 20 inches high by 22 inches deep, it delivers up to 1,389 CFM at a maximum face velocity of 500 FPM. The synthetic media captures 40 to 45 percent of targeted particles across the MERV 11 range and carries a UL 900 listing. An integrated frame holds the bag assembly rigid during installation and throughout the service cycle. Maximum working temperature is 150 degrees F. Licensed HVAC technicians and building service contractors install this filter in standard commercial air systems.
This filter fits commercial rooftop units, central air handling units, and makeup air equipment where nominal 20 x 20 inch filter banks are specified. The 22-inch bag depth provides extended media surface area suited for moderate-to-heavy dust loading environments such as light manufacturing, schools, office buildings, and healthcare facilities. The 5-pocket design distributes airflow evenly across the media and helps maintain stable static pressure drop across the filter bank over the service interval.
Designed as an OEM-style replacement bag filter for commercial HVAC air handling units and fan-coil systems accepting a nominal 20 x 20 x 22 inch bag filter with a standard 5-pocket configuration.
Installation is performed by licensed HVAC technicians or qualified building service personnel. Before servicing the filter bank, shut down the air handling unit and verify the unit is fully de-energized. Inspect the filter housing tracks and sealing surfaces for gaps before inserting the filter to ensure full face coverage and prevent bypass. Dispose of used filters in accordance with applicable local waste regulations and follow any facility infection-control or dust-containment procedures where required.
