Here’s the truth bomb: reverse osmosis is incredible for taste and purity. If you live in a place with weird-tasting or sketchy water, it’s a game-changer. But it’s also a huge pain. You’ll need a system under your sink that looks like a robot octopus, and it wastes about 3-4 gallons of water for every gallon it produces. That’s like buying a car that burns a tire for every mile you drive.
Some systems now have permeate pumps that reduce waste, but it’s still not eco-friendly. If you’re the kind of person who feels guilty about leaving the tap running while brushing, RO might give you a mild existential crisis.
