What is the history of Binchotan charcoal?
Binchotan charcoal, which is often referred to as ‘white charcoal’, has a rich history, although it’s origins are not totally clear. It was thought to have been introduced to Japan by a scholar called Kukai, and a monk, about 1,200 years ago. It wasn’t until the 17th century that it became popular, thanks to a man named Binchuya Chozaemon.
How is it made?
Making Binchotan charcoal requires a very fast rise in temperature, and then rapid cooling, which leaves a hard and smooth surface. If you tap it, you’ll hear a clear, metallic sound. The process to do this involves taking sustainably sourced wood, and charring it at a low temperature in a kiln for a long time. Just before it’s finished, the temperature suddenly is increased to about 1000°C until the wood is red hot. A special powder is created from earth, ash and sand, and this is used to quickly cover the charcoal once it’s removed from the kiln. This process is what gives the charcoal a white hue (which is why it’s sometimes referred to as ‘white charcoal’).
How does it work?
It has a very porous surface with tiny holes (or cavities) throughout the material. These tiny holes attract contaminants like chlorine and hold them to the surface of the charcoal, and therefore away from the water you drink. It also releases minerals like magnesium and iron into the water.
How much water can each charcoal filter?
One stick of Binchotan charcoal can filter about 1.1L of water, if used every day for 3 months. Just scale up or down depending on the volume of water you’d like to filter.
How long will it last?
About 3 months if you use it every day with our ‘Eau Good’ range. You can then boil it for 10 minutes to ‘recharge’ it, make sure you leave to dry in the sunlight. This recharging will make your charcoal last another 3 months.
What other uses does the binchotan have?
Binchotan has lots of secondary uses after it’s finished as a water filter: it adds nutrients to the soil of houseplants (simply break it up and add to the pot), you can use it to deodorise a laundry basket, cat litter or shoes, it even can absorb moisture from the air, acting as a great dehumidifier in your wardrobe.
Do I need to wash my charcoal?
No, it’s ready to use straight out of the packaging.
Can I use my binchotan with flavoured water (fruit infused or tea)?
No, do not use anything to flavour your water with the Binchotan charcoal.
Can I wash my bottle with soap and leave the charcoal in it?
Make sure you remove the charcoal stick before washing your bottle with soap.
Where can I order more charcoal from?
You can buy more charcoal directly from our website, please see the Accessories page.
Is it dangerous if I swallow a bit of charcoal?
No, swallowing small pieces of charcoal will not be harmful. Sometimes small particles or fragments may break off your charcoal stick and float in your water, you can simply rinse these out, but it will not be dangerous if you swallow them.
What’s the best way to clean my bottle?
We recommend washing your bottle with a bottle brush and hot, soapy water regularly. You can also put the bottle in the dishwasher, however please note the material tag may be damaged with frequent dishwashing. Although the cork is not dishwasher safe, you can remove the silicone seal and put this in the dishwasher.
Is it possible to prevent mould from forming on my lid?
If you leave water in your bottle for a long time, mould spores can form. Because Binchotan charcoal removes chlorine, this process can sometimes happen more quickly, so it’s best to make sure you empty your bottle after use, and ideally wash the silicone stopper. Don’t leave water sitting for longer than a couple of days. Always store your bottle without the lid off.
If it does form, how can I clean the mould off the lid?
To remove mould from the silicone covering, simply apply fresh lemon juice, and then boiling water. This will wash away and kill any spores which have formed.

Introducing Binchotan charcoal
Why charcoal?
Japan has been using active charcoal to soften and filter water for centuries. As an active carbon, it not only can filter and purify water, but also air. It acts as a fantastic deodoriser and dehumidifier.
How do I use it?
You can use your charcoal immediately from the packaging, simply lock it in place inside the coil, and carefully drop it into the bottle. Then fill your Eau Good Glass with tap water and wait for it to purify the water. Leaving overnight is ideal for the first use, but you will notice the difference in taste after only 1 hour. Your charcoal and coil can be used in any bottle, jug or vessel.
How long can I use it for?
The charcoal will last about 3 months, after this time you simply need to boil it in water for 10 minutes to reactivate it’s filtering abilities. This helps the charcoal to expel any contaminants it has been holding, and free up space to absorb more. It will then last another 3 months.
Did the charcoal break?
Don’t worry, it will still work, but if you’re not sure there are plenty of other secondary uses for charcoal. Simply view the FAQs section at the top of this page to learn more.
