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. The lid is not dishwasher safe, but the silicone seal is dishwasher safe and is easy to remove for thorough cleaning.

Features
WOOD FIBRE LID & CARRY LOOP
The leak proof lid has a polypropylene and wood fibre top and stainless steel loop that makes it easy to carry. The silicone seal is easy to remove for thorough cleaning. The stainless steel cap on the underside of the lid ensures there is no plastic coming into contact with your water.
CHARCOAL LOCKS IN PLACE
The stainless steel coil ensures the charcoal does not move or rattle inside the bottle, even without water.
ECO PROTECTIVE SLEEVE
The sleeve is made from recycled polyester. It helps protect the glass, insulate the water (keep it cool), makes it easier to grip and stops condensation forming on the outside of the glass.
THREAD ON INSIDE FOR SMOOTH DRINKING
The thread is on the inside of the bottle so the outer lip is smooth and gives a better drinking experience. The Borosilicate glass is taste neutral so combined with the charcoal filtration, you get the best tasting water and drinking experience.
A WORD FROM THE DESIGNER
We wanted to upgrade and improve are ever popular glass filter bottle. Having a threaded lid makes it easier to open and close and is just as secure and leak proof as before. It requires skilled glassmakers to hand blow this detail but ensures that the bottle is a pleasure to drink from. The wood fibre lid has the same visual appeal as the original cork design but is harder wearing and the stainless steel carry loop makes it easy to hold and unscrew. The silicone seal is easy to remove (and reapply) for thorough cleaning and the stainless steel cap on the underside ensures a plastic-free contact with your water. One of the biggest improvements was changing the sleeve from neoprene (known for not being environmentally friendly) to a recycled polyester that still protects and insulates the water inside. The visual appeal of the design remains, but the new design is stronger and harder wearing for on-the-go use.
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.
