What is it made from?
The binchotan active charcoal is made from 100 percent natural hardwood oak.

How does it work?
Step 1: fill your carafe or bottle with potable tap water and place your ready to use charcoal stick inside. Step 2: leave the activated charcoal for at least one hour to remove impurities.

How long does it last?
The water filter lasts for 6 months. We recommend that after 3 months you recharge the stick by boiling it for ten minutes. This will extend the lifespan by another 3 months.

Can it be recycled?
Yes after its life as a water filter is finished, you can recycle it for many secondary uses (e. g. burn it on the BBQ, crush it up and put it in your soil to act as a fertiliser or even put it in your shoes to deodorise them!)

Specifications and precautions
It is ultrasonic cleaned and ready to use immediately (without needing to boil it) and that is why it comes in a vacuum pack. If you swallow particles of the charcoal, it will do you no harm. Doctors prescribe it to treat diarrhoea, indigestion and flatulence. Minimum spout opening: 3cm
