Are these things expensive? They can be. A good under-sink unit costs $200 to $600. But bottled water is way pricier over time.
Still, you’ll pay for the filters. You have to change them every 6 to 12 months. Forget to do that? Your water starts tasting like regret and old socks.
So it’s a commitment. Like adopting a pet fish, but it lives in your plumbing and doesn’t need feeding.
What Is Reverse Osmosis And How Does It Work
A Bizarre Side Effect
Reverse osmosis water is too pure. It’s so stripped of minerals that it can taste flat. Some people add a pinch of salt back in.

But the flavor is worth it for many. It’s like the difference between a stale cracker and a fresh baguette.
