You’ll need to swap out the filters every six to twelve months. That’s it. It’s not rocket surgery—just unscrew the old cartridge, screw in the new one, and do a little happy dance. The membrane (the super-star) lasts two to three years, so you can forget about it for a while.
Most systems come with a little reminder sticker or a light that tells you when it’s time. It’s like your water is talking to you, but in a polite, non-creepy way. “Hey, I’m getting tired,” it says. “Give me fresh guts.”
And if you forget? The water just slows down a bit. No catastrophe, no floods. It’s the most forgiving appliance you’ll ever own, like a golden retriever made of plumbing.
