Now we hit the real hero: the reverse osmosis membrane. This is the star of the show. Imagine a mesh so fine it only lets water molecules through.
It pushes water through at high pressure, leaving behind almost everything else. We’re talking lead, arsenic, fluoride, pesticides, and even tiny microplastics. It’s like a giant magnet for nasties.
Why is this cool? Because it’s dramatic.
The RO membrane is thirsty work. It will reject about 80-90% of the water it sees as “waste” to make the rest pure. That sounds wasteful, but think of it as concentrated effort for a crystal-clear result.
