A filtered vent system for a return air duct in a ceiling, the vent system comprising:
- a mounting frame for fixation to the ceiling;
- a vent frame mounted to the mounting frame;
- a vent plate carrying an air filter;
- a hoist arrangement mounted to the vent frame and connected to the vent plate;
- wherein the hoist arrangement is actuable through an aperture in the vent frame to move the vent plate from a first state in the vent frame to a second state axially outside the vent frame and spaced apart from the vent frame a distance permitting removal of the air filter.
A method for replacing an existing vent return plate and existing air filter for a filtered return air vent of a ceiling duct, the method comprising the steps of:
- disconnecting the existing vent return plate from an existing frame surrounding the air vent;
- removing the existing air filter from the filtered air return vent;
- fixing a mounting frame to a portion of the ceiling surrounding the existing frame;
- mounting a vent frame carrying a vent plate with a new air filter to the mounting frame and over the existing frame, the new vent plate moveable relative to the new frame between a closed state in contact with the frame to an open state wherein the vent plate is free from contact with the frame.
