The unique thing about the iWash faucet is that it gives a visual representation of the bacteria and other germs present on our hands, which diminish as we lather and get them clean. No doubt, the best was to keep infections in check is by washing our hands as often as possible. Building on this theory, the iWash is a pretty neat innovation that nudges us in the right direction. Basically it lays importance on creating awareness and practicing self-sanitization.
