Abstract
A filtered vent system for a return air duct in a ceiling, the vent system includes a bracket configured to mount to the ceiling. A vent frame mounts to the bracket to fix the frame to the ceiling. A vent plate carries an air filter. A hoist arrangement is mounted to the vent frame and is connected to the vent plate. A hoist arrangement is actuable through an aperture in the vent frame to move the vent plate from a first state in contact with the vent frame to a second state free from contact with the vent frame and spaced apart from the vent frame a distance permitting removal of the air filter.
