The Binchotan in size XL is indicated when the water requires reinforced filtration (poor quality water, water with an unpleasant taste, etc.)


Depending on the initial water quality, plan: 


- 1 stick for  1.5 to 2 L of water if the water is correct

- 1 stick for 1 L of water if the water is of poor quality and has a strong unpleasant


(if your carafe  is of another capacity, do not hesitate to contact me to determine the exact quantity of Binchotan you will need)


One stick of Binchotan XL can purify up to 6 L of water per day for 6 months, i.e. 1080 L of water (= 720 1.5 L plastic water bottles) for a cost price of €5 per month.

Weight: 40 grams approximately (due to the natural origin of the product, the weight may vary slightly).




All our Binchotan are labeled by the Wakayama Prefecture in Japan and they all bear the yellow certification sticker, as a sign of their authenticity.


Beware of counterfeits, 90% of the Japanese Binchotan coals from Kishu sold in France are actually from China, Indonesia or Laos.

    A stick of Binchotan  approved for water filtration by Wakayama Prefecture, usable in carafes or jugs  with a maximum capacity of 1 liter and a half.




    1) bring a stick of Binchotan and  a glass or pottery carafe (you can reuse a  clean fruit juice bottle).

    2) make boil the bâtonnet de_cc781905-5cde- 3194-bb3b-136bad5cf58d_charcoal for 15 minutes in a pan of water before using

    3 ) take it  out of the water and let it  dry for about 15 minutes.

    4) insert the bâtonnet  into the carafe or pitcher

    5) let the charcoal act for 8 hours.


    The ideal is therefore to start the night before and let it act for a whole nuit. 


    An activated carbon stick is economical because it is used for 6 months. It is also ecological because it avoids the massive use of mineral water bottles and plastic filter jugs.


    Each month, all you need to do is purify your coal  by boiling it again in a pot of water for 15 minutes.

    Beyond 6 months, the carbon being saturated, it will be necessary to change it.

    It is recommended not to leave a charcoal in the same water for more than 48 hours. If this is the case, all you have to do is empty the water and let the charcoal act again for  8 h.


    What to do with used coals? 

    Do not throw away your used coals! They can still be used to reduce odors in the refrigerator or shoe cabinets. You can also  use them for decoration (some make pretty  chimes  or xylophones_ cc781905-5cde-3194-bb3b-136bad5cf58d_thanks to their sound_cc781905 -5cde-3194-bb3b-136bad5cf58d_metallic).
