Active Binchotan Charcoal Water Filter
Binchotan active charcoal is used to filter water by absorbing impurities such as chlorine, and adding minerals such as calcium. These charcoal refills are pre-washed and vacuum sealed so they are ready for immediate use. Simply drop the charcoal into your water, we recommend one stick per litre, then leave for 1 hour and enjoy your filtered water. Each charcoal will last for 6 months as a water filter. They are then recyclable for other uses around the home, such as plant fertiliser.
The natural charcoal filter can also come with a locking coil that upgrades any standard bottle into a ‘filter bottle’ using a traditional Japanese Binchotan charcoal method for cleaner tasting water.
Why do you use Binchotan
Binchotan charcoal has been used for centuries in Japan to purify and soften water. As an active carbon it attracts contaminants like chlorine and binds them to its surface, away from the water you drink.
How quickly will it work?
You will notice the difference in taste in about 1 hour, but it ideally can be left overnight for first use. The charcoal can be used directly from the packaging, straight into the coil and into your bottle or jug.
When will it run out?
After about 3 months, you may notice a decline in taste. At this point, you can simply boil the charcoal in water for 10 minutes to recharge it, then use for an additional 3 months.

Where did Binchotan charcoal come from?
It was during the Edo Period (17th century) that a man called Binchuya Chozaemon made it popular, but the origins are not completely clear.

What is the process for making Binchotan charcoal?
This ancient process for making Binchotan charcoal is very interesting, and also intense. The wood needs to be raised to very high temperatures in a kiln, and then rapidly cooled by being covered in a mixture of soil, sand and ash. This gives the charcoal it’s very hard and smooth appearance, and if you tap it, you’ll hear a clear, metallic sound.
What makes it a good water filter?
Not only does Binchotan charcoal remove impurities from water, it can also release minerals back into your bottle, improving health and taste.
