- The model 2000S Hydration By Haws™ bottle filling station is a touch-free, hygienic, water dispenser that allows users to enjoy the benefits of fresh, filtered water with none of the drawbacks of bottled water. The system is tested and certified by CSA against NSF/ANSI Standard 42 for the reduction of chlorine (taste and odor) and against NSF/ANSI Standard 53 for the reduction of lead and cysts. Recessed, in-wall-mounted design allows the bottle filling station to be placed securely in multiple locations without taking up excess space. The unit conveniently mounts between standard 16 in studs and is practical for permanent, high-traffic applications such as schools, office buildings, fitness centers and manufacturing facilities.
