If you live somewhere with genuinely nasty tap water (think: rust, chlorine smell, or lead), an RO system is a game-changer. Your pasta will taste better, your coffee won’t have a metallic aftertaste, and your skin might stop throwing tantrums. But if your tap water is already decent? You’re basically paying for peace of mind and a slight upgrade in taste.
My advice? Start with a $40 faucet-mounted filter for a month. If you still feel the pull towards RO, then buy the mid-range model. Your future self will thank you—or curse you when you have to change the membrane at 3 AM.
Either way, just know this: no RO system in the world will make your tap water taste as good as the free water from your grandma’s garden hose. That flavor is non-negotiable, and it costs $0.
