You need an RO system if your tap water tastes like a chemical lab. If you live in an older house with lead pipes, this is practically a health insurance policy. It’s also a godsend for people who hate the mineral aftertaste of bottled water. On the flip side, RO strips out everything, including healthy minerals like calcium and magnesium.
That “pure” water is essentially empty. Some people call it “dead water.” But honestly? It’s dead delicious. You can always add a re-mineralizing filter later if you’re worried about missing out on rocks. Most coffee snobs will tell you RO water makes the best cup because it doesn’t react with the beans.

The little annoyances nobody tells you about
First, noise. The system makes a gentle gurgling sound when it’s flushing the rejected water down the drain. It sounds like a tiny toilet. You’ll stop noticing it after two days. Second, the storage tank. Most units have a big blue tank that holds about 3 gallons. That tank takes up half your under-sink cabinet space. Say goodbye to storing your stockpot there.
And third, the filter changes. You have to swap out the pre-filters and post-filters every 6 to 12 months. The membrane itself lasts 2 to 3 years. If you forget, your water goes from “crisp mountain stream” to “slightly sad pond.” Set a calendar reminder, for the love of hydration.
