Let’s keep it real. These systems aren't perfect. They waste a bit of water—usually about 3-4 gallons of “used” water for every 1 gallon of purified water they make. That “used” water just goes down your drain.
Also, they strip out the good minerals along with the bad. If you drink a ton of RO water, you might miss out on calcium and magnesium from your water source.
But honestly, you get most of your minerals from food anyway. Unless you exclusively drink water and never eat broccoli, you’ll be fine. Some people even buy mineral drops to add back in, like they’re spicing up their water.
Who Actually Needs This?
If you live in a house with well water, this is a game-changer. Well water can have all sorts of mystery guests like rust or sediment. An RO system is basically your personal water treatment plant.
Even if you’re on city water, the taste difference is astonishing. No more funny aftertaste from plastic bottles or weird smells from the pipes.
Plus, think about the plastic bottle waste. You can fill up a reusable water bottle from your sink all day long. You become a sustainability hero without even trying.
