The TRION P101-1625T is a 16 x 25 x 3 inch expandable cartridge media air filter designed for compact media air cleaner cabinets. At 3 inches deep, it delivers high-efficiency filtration in space-constrained installations where standard 4-inch or 5-inch media cartridges will not fit. The expandable cartridge design allows the media to open fully once installed, maximizing filter surface area and maintaining adequate airflow across the cabinet. HVAC technicians and service professionals install this filter as a scheduled maintenance replacement in residential and light-commercial air cleaner systems.
This filter is engineered for use in Air Bear Cub style media air cleaner cabinets, which are commonly installed in residential forced-air heating and cooling systems where cabinet depth is limited. The 16 x 25 inch face dimensions fit the standard opening of compatible Cub-style housings. It is a direct drop-in replacement for technicians servicing existing Air Bear Cub installations without requiring modifications to the cabinet or ductwork.
Designed as a replacement cartridge filter for Air Bear Cub style compact media air cleaner cabinets accepting a 16 x 25 x 3 inch expandable filter.
Installation is performed by a qualified HVAC technician. Power down the air handler or furnace at the disconnect before opening the media cabinet and removing the spent cartridge. Allow the replacement cartridge to fully expand before sliding it into the cabinet to ensure a proper seal against the frame. Follow applicable local codes and the cabinet manufacturer instructions for maintenance intervals.
