Imagine you have a really nosy bouncer at a club. Only the purest H₂O molecules get through, while everything else—minerals, bacteria, your neighbor’s lawn chemicals—gets kicked to the curb. That’s RO in a nutshell.
It uses a semi-permeable membrane that’s so picky, it makes a gold-medal sommelier look laid-back. The result? Water that’s so clean, you’ll half expect it to have its own Instagram account.
Pro tip: RO systems do remove good minerals too, so don’t panic. We’ll cover how to fix that later. (Spoiler: it involves a little reminerlization magic.)
