Okay, let’s be real. RO systems have one annoying habit: they waste water. For every gallon of filtered water, they might send 2-4 gallons down the drain. That sounds terrible, but modern systems are getting better (some waste only 1:1). Plus, you can use that “waste” water to water your plants—just don’t tell them it’s the rejected stuff.

Also, installation can be a bit of a DIY affair. If you’re handy, you can do it in an afternoon. If you’re like me, you’ll end up with a tiny leak and a puddle that looks like a crime scene. Pro tip: just hire a plumber or bribe a friend with pizza.
And here’s the weirdest part: RO water is so pure that it can taste “flat” if you’re used to mineral water. Some people add a dash of pink salt or a slice of lemon to bring back the “zest.” It’s like giving your water a little personality.
