Compared to regular water dispensers, a touchless unit means you won’t need to press a button for the machine to dispense water. As such, you can do this one-handedly, freeing your other hand to do or hold other things. Because you don’t touch the machine as often as you would if it were a regular water dispenser, the risks of wear and tear are also minimized. What’s more, this design choice also lowers the chances of bacteria from growing and getting passed on from one person to another.
