You could easily buy bottled ionised water, but where’s the fun in that? Making it at home lets you control the pH level and saves you from all that plastic waste. Plus, it’s a great party trick—imagine pulling out a glass of water that you electrified yourself.
It also saves money. Most countertop ionisers pay for themselves after a few months, and you get to feel like a mad scientist every morning. Who wouldn’t want that?
