Water delivered from a water cooler which does not have a bottle. Once a bottleless water cooler has been installed, it’s ready to use and there are no bottles to replace. Costs are lower. There are various filtration types, and filtration is done within the machine itself. With closed systems and sanitation features, and no BPA from plastic bottles, the water is clean and safe. As there are no bottles to replace, there’s no oil used to make plastic bottles or to ship the full and empty bottles, so bottleless water is a much more environmentally-friendly solution.
