Reverse Osmosis is not a superhero. It can’t remove everything. It struggles with chlorine (that’s why you need the carbon filter). It also can’t remove some tiny viruses unless you have a special membrane.
And it’s not perfect for everyone. The waste water (the brine) is a real bummer. But for people with hard water, well water, or just a fear of tap water, it’s a game changer.
The simplest way to think about it: It’s a bully for bad water. It pushes, it shoves, and it leaves you with a sip of perfection. Try it. Your taste buds will throw a party.
