Let’s compare: A Brita pitcher sits in your fridge like a lazy roommate. It filters a little, but it leaves behind fluoride and heavy metals. An RO system under your sink is the overachiever—it filters everything, including the fluoride your dentist keeps swearing by. So, you might need to add a pinch of salt or a mineral drop back in. Or just eat a yogurt and call it even.
And here’s the kicker: RO systems are not just for people with “mysterious well water.” Even in cities, tap water can contain trace pharmaceuticals, microplastics, and the occasional hormones from agricultural runoff. Yes, your water might have a little bit of someone else’s birth control. You’re welcome for that mental image.
