Reverse osmosis is so good at stripping everything, it also removes healthy minerals like calcium and magnesium. That’s right: your water might taste so pure it’s almost empty. Some people call it “flat” or “sad water.” If you’re a mineral snob, you can buy a remineralization cartridge that adds them back in—like putting pearls on a tuxedo.
Also, tankless systems use electricity to pump water through the membrane. If the power goes out, your super-pure water dreams evaporate faster than your willpower at a donut shop. But hey, that’s what emergency bottled water is for (the kind you bought before you went bougie).
