So the other day someone asked me a question about the black thing in the water pitcher for my Iced Americano video.

The black thing is bamboo charcoal, and here I’ll introduce how I use it to purify the water and get rid of the chlorine smell.

The tap water in Japan is generally quite safe but the one thing that I don’t like is the faint chlorine smell. It definitely is unpleasant when you think about sipping it or using it for pour over coffee.

Charcoal has been used for centuries to filter water and has cleansing properties. What’s awesome is that it can also get rid of the chlorine smell, and here I’ll show you how I actually do it.

Let’s begin.

First I prepare my copper pot where I’ll be boiling my bamboo charcoals.

Pour water inside.

Heat it and bring to a boil.

Use tongs and move the charcoal into a container. Here I’m using a glass jar. You don’t have to use the water that you used to boil the charcoal with.

Pour tap water into the jar.

And you’re done. Now all you have to do is wait for about 12 ~ 24 hours for the charcoal to do its thing and clean the water. You’ll probably be surprised by the lack of chlorine smell in the water. What’s more, the water may taste slightly sweeter.

This is ideal for drinking or making coffee. A very primitive but useful and beneficial way of cleansing water and cutting costs if you usually buy water. One thing you should keep in mind is that the tap water in Japan is relatively clean. I’m not sure about the situation in your country or city, so just make sure the tap water is considered drinkable and then proceed onto cleaning it with bamboo charcoal.

The charcoal is just the average charcoal and not activated. I don’t think there’s any problem even if you used activated charcoal but then you probably don’t even need to boil it. I’m guessing that boiling average charcoal activates it but I may be wrong.

I hope you found this post useful.
