Exhaust in Copy Rooms

In one of our projects, the client is willing to have open spaces with high flexibility. In these open spaces, “boxes in the box” for copy rooms will be created. As the location of these boxes is flexible, the mech engineering cannot run any exhaust duct. He is suggesting the use of an active charcoal carbon filter with a fan to exhaust the air from the copy rooms to the open spaces. The contaminants would be filtered before the air is transfered and then exhausted through return ducts in the open spaces. Has anyone had experience with this? We don’t find anything about this topic in ASHRAE 90.1. Thanks for your help!
