Is Distilled Water the Same as Pure Water

Is Distilled Water the Same as Pure Waterの注目されている理由を専門的かつ分かりやすくまとめました。全体像を一目で把握できます。

Distilled water is a type of pure water—but with a specific backstory. It’s made by boiling water into steam, then condensing that steam back into liquid. It’s like giving water a sauna session and a cold shower, all in one go.

This process strips away almost everything: minerals like calcium, magnesium, and iron, plus bacteria, viruses, and even some chemicals. What’s left is nearly pure H₂O, but not quite 100% pure.

Why “nearly”? Because some volatile compounds (like certain alcohols or gases) can hitch a ride with the steam. So distilled water is extremely pure, but it’s not the Holy Grail of absolute purity. It’s the 99.9% clean friend who still has one questionable sock.

So, What’s the Difference?

Imagine you’re trying to make the perfect cup of coffee. Pure water is the water in a chemistry textbook—nothing in it but H₂O. Distilled water is the water you get after boiling your kettle and catching the steam.

Distilled water is a method to get close to pure water, but it can still carry tiny traces of what it touched. Pure water, on the other hand, is the end goal—a Platonic ideal that’s hard to reach without a serious lab.

In everyday life, most people use “pure water” loosely to mean water that’s safe to drink and free of contaminants. But rigorously speaking, distilled water is not identical to pure water—it’s just the closest we can practically get without building a billion-dollar facility.
