If you live in a place where the water tastes like a municipal pool that’s been through a rough week, yes. Do it. If you just want bragging rights at dinner parties, also yes. It’s a relatively cheap way to feel like you’re on a private island, minus the sunburn and the sand.
Just remember: it’s slow, it’s a little wasteful, and it will turn you into that person who brings their own water to restaurants. But hey, your kidneys are the real VIPs here, and they deserve the best seat in the house. So go ahead, get a little reverse osmosis in your life. Your taste buds will get bored, but your body will throw a tiny, hydrated party.
