Okay, picture this: you have a strainer for pasta, but the holes are so tiny that even a single grain of salt can’t get through. That’s basically reverse osmosis, or RO for short. It uses pressure to push water through a super-fine membrane that acts like a bouncer at an exclusive club.
This bouncer only lets the good stuff through—pure H2O. Everything else—chlorine, lead, pesticides, and even that weird mineral that makes your tap water taste like a metal spoon—gets kicked to the curb. It’s not magic, but it sure feels like it when you take that first sip.
