What is the story behind Binchotan charcoal?

Thanks to a man named Bichuya Chozaemon, Binchotan charcoal became popular in about the 17th century, however its history goes much further back than that. Sometimes referred to as ‘white charcoal’, this incredible natural material was thought to have been introduced to Japan by a Japanese monk, and a scholar, about 1,200 years ago.

How do you make it?

In a kiln at a relatively low temperature, we place sustainably sourced wood for a long time. When the wood is nearly done, we will suddenly increase the temperature to around 1800°F until it is red hot. The wood is removed from the kiln and quickly covered with a blend of earth, ash. and sand to cool it rapidly. The charcoal then becomes almost white, also why it’s sometimes referred to as ‘white charcoal’. This process of rapidly heating wood, and then rapidly cooling it, incinerates the bark and leaves a smooth, hard surface. Tap it, and you’ll clearly hear a metallic sound.

How does it filter water?

Charcoal is an incredibly porous material, filled with tiny little cavities or holes, which attract contaminants like chlorine. These contaminants are held to the surface of the charcoal, and therefore away from the water you drink. And don’t worry about these holes getting filled quickly, there’s enough surface area in just 0.04 oz of charcoal to cover 5400 square feet! Binchotan charcoal can also release minerals into the water, improving taste and benefiting your health.

How much water can I filter with a charcoal stick

About 37fl oz of water can be filtered with one stick, over 3 months if used every day. If you’d like to filter more water, simply increase the number of sticks in your jug or container.

How long does charcoal last?

Using our ‘Eau Good’ bottles, your charcoal will last about 3 months if you fill it up once a day, every day. You can then simply boil it for 10 minutes which will reactivate the charcoal, and once dried in the sun, or near a window, you can use it for another 3 months.

What do I do with my charcoal when it’s finished as a water filter?

So much! Because charcoal is so porous, it acts as a deodorizer, so can be used in your cat litter, nappy bin, shoes or laundry basket. It will also add nutrients to the soil if you break it up and add to houseplants, and if you pop it in your wardrobe it will absorb the moisture from the air helping your clothes avoid becoming moldy.

Does the charcoal need washing?

You do not need to wash the charcoal, it can be used directly from the packaging.

Can I flavor my water with the charcoal stick in?

Please do not add anything to flavor your water if you’re also using a Binchotan charcoal water filter.

How do I wash the bottle with Binchotan charcoal in?

Please remove it before washing your bottle if using soap.

How do I buy more charcoal?

What happens if I swallow a piece of charcoal?

leak free design

The easy open spout has been specially engineered to give a great flow of water (more than your average sports cap, with no squeezing required) and also has a reassuring leak proof closure.

drop & lock system

The natural charcoal makes your tap water taste great! The bottle shape allows you to simply drop, squeeze, and lock the natural active charcoal filter in place so it won’t move about in your bottle.

infuser guard

The guard allows you to add different fruits and herbs to your bottle and infuse the healthy flavors into your water.

great drinking feel

If you want to drink directly from the bottle instead of the spout, we've put the thread on the inside, so it feels like you are drinking from a glass!

easy hold

The ergonomic form makes it easy to carry when on the move and the silicone strap allows you to relax your hold while gripping the bottle. For quick simple convenient carrying, we’ve also included a finger loop.

easy clean

Unlike other sports bottles, our cap can be disassembled for easy cleaning.

why charcoal for filtering water?

As an active carbon, charcoal works by attracting the negative ions in impurities like chlorine, and binding them to its surface. It has been used in Japan to purify and soften water for centuries.

how do i use it for filtering water?

Our binchotan charcoal can be used immediately - simply remove it from its packaging and place it in any bottle or jug. Once filled with water you’ll notice an improvement in taste after about an hour.

does it ever stop working?

If used daily to filter 37 fl oz of water, each stick will last about 3 months. You can then “recharge” your charcoal stick by placing it in boiling water for 10 minutes. This process reactivates the charcoal and removes the contaminants that have been building up on its surface and allows it to filter your water for another 3 months.

what to do if it breaks?

Your charcoal will still work even when broken. However, if you’d prefer to buy another, you can still use the broken pieces in many different ways. To know more about this, have a look at our blog.

a word from the designer

We wanted to create a sports bottler version of our popular Eau Good filter bottle. Using the same 'drop & lock' system that securely holds the natural binchotan charcoal in place, we added a fast flow pop up spout and silicone band that made it easy to hold while running. All the components are easy to take apart for easy cleaning and we even have a simple diffuser guard so you can add natural herbs and fruit to flavor your water.
