Difference Between Distilled Water and Reverse Osmosis

Difference Between Distilled Water and Reverse Osmosisにまつわる興味深い視点を分かりやすく発信ます。

Reverse osmosis (RO) is the cool, modern cousin that uses pressure to push water through a semipermeable membrane. Imagine a very picky bouncer at a club who only lets the smallest molecules (water) slip past, while kicking out everything else: lead, chlorine, fluoride, and even some viruses.

It’s not boiling; it’s squeezing. RO systems are standard in many homes and even in desalination plants where seawater turns drinkable. A fun cultural reference: in “Breaking Bad,” Walter White used reverse osmosis to purify chemicals—talk about a high-stakes water cooler.

RO water still contains some dissolved gases (like oxygen), so it can taste crisper and fresher than distilled. But it’s not perfect—it wastes a bit of water in the process, and it strips out healthy minerals like calcium and magnesium.
