You can get a decent under-sink RO system for around $150 to $300. That’s less than a nice dinner for two at a fancy restaurant. And a lot less than buying bottled water for a year (remember, plastic bottles are a crime against turtles).
The filters? You change them every 6-12 months. The membrane? Every 2-3 years. It costs maybe $50-100 a year. Compare that to buying a pack of 24 water bottles every week. Math is fun. You win financially, and the planet wins too.
The “Do I Really Need This?” Test
Take a glass of tap water. Let it sit for five minutes. Does it smell like a swimming pool? Does it leave white spots on your glasses? Does it taste like iron? If you answered yes to any of these, you need this filter.
If you live in a city and your water is already decent? You might not “need” it. But you’ll still want it. It’s like upgrading from a bus ride to a convertible. You don’t need the wind in your hair, but man, does it feel good.
It’s also a lifesaver if you have kids. They get dehydrated easily, and they hate water that tastes weird. RO water? They’ll chug it like it’s lemonade (without the sugar crash).
