This is Binchotan charcoal. It’s an active carbon made from sustainably sourced hard wood (not to be confused with your average BBQ charcoal). This amazing material has been used by the Japanese to filter water since the 17th century. It's renowned for its ability to soften water, add good minerals, balance pH and adsorb* unpleasant tastes and odours.
*Yes you did read that right! Adsorb means to hold (molecules of a gas or liquid or solute) as a thin film on the outside surface or on internal surfaces within the material.
Due to its high degree of microporosity, just one gram of Binchotan has a surface area in excess of 250 m2, which is the same size as a tennis court! The positive ions of contaminants in the water are attracted to the negative surface of the carbon where they are held. In reverse the charcoal releases its natural minerals.
How long does it last? It has an amazing 6 month life span.

Simply drop your charcoal into your bottle, squeeze the sides of the bottle so that the charcoal sits in the groove (as much as it can), then relax your grip to lock it in place.
We are so proud of our charcoal filter that we didn't want to hide it in permanent plastic casing - this means it is very easy to recycle and won't end up in landfill.
After the 6 months of water filtration, one suggestion is to break up the charcoal and put in in your plant pots to remineralise the soil.
Yes, just like that! Thanks to the built-in infuser cap, you can simply fill the bottle with your favourite fresh fruits and herbs (cucumber, lemon, mint etc.). There's no limit to the healthy cocktails you can make (just ensure that you remove the charcoal first).
What’s that all a-spout? The spout has been specially engineered to allow a great flow of water. If you want to drink direct 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!
Super silicone! Our unique dual silicone strap design makes this bottle super easy to hold. Whether you're out running on an ultra marathon or even just jogging... to catch a bus, this design is ergonomic and easy to hold. The strap even allows you to relax your grip and the bottle stays with you. The soft-touch carry loop makes it easy and comfortable to carry with one finger or hang from your bag.
The perfect size. Our bottle is designed to conveniently fit in most cup holders and cycling bottle cages (not fixed diameter bottle cages).
It scrubs up well. It's essential with water bottles that you clean them regularly. Unlike most other bottles, ours is easy to disassemble enabling you to really clean all the areas, and it's dishwasher safe.
Made of safe and durable materials. Our bottle is made from BPA, BPS and phthalate free Tritan™ and premium quality polypropylene. Tritan™ is a brand of co-polyester made in the USA by Eastman. It is clear, durable, taste neutral, lightweight, and you can rest assured that no nasty chemicals are leaching into the water.
