Why does the Vapor-Clean include two activated charcoal filters?
The primary reason for including two filters is to increase anesthetic gas removal in the intra-operative application. Additionally, the dual filter prevents inhalation of vapor in case one of the anesthesia machine’s non-rebreathing valves fails. An additional safety reason for the dual filter configuration is to minimize the possibility of inadvertent placement of a single charcoal filter on only the expiration hose port.
