A vacuum and piping system can be installed on tables, bars, and the like, quickly and effectively for the purpose of removing cigarette smoke. The multi-component system includes vacuum nozzles, ashtrays which are threadably attachable to the nozzles, a system of smoke removing piping, and a large filtering tank and vacuum cleaning unit located at a remote location. The vacuum cleaning unit employs a wet and dry vacuum cleaner to pull cigarette smoke from ashtrays and overhead smoke capturing nozzles and direct it to a water filter for cleansing. The ashtrays are fixedly secured to tables and bars, and they include threadably openable and closeable nozzles. When open, the nozzles may be used to withdraw cigarette smoke to the cleaning filter, and when closed, water may be piped through the system for purposes of removing captured ashes and other debris. The nozzles may also be partially opened to allow a fine spray of water to be directed into ashtrays so that they can easily cleaned with a hand cloth.
