Genuine Japanese Binchotan, 20 gram stick (size M) for 1L carafes


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




    1) plan a stick of Binchotan for a carafe with a capacity of one litre maximum, preferably in glass (you can reuse a small bottle of fruit juice) or in terracotta.

    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). You can also  put them in  the barbecue (it is a very slow burning wood, which will release little_cc7 81905-5cde-3194-bb3b -136bad5cf58d_ smoke or smells), or compost it. 

    Binchotan is totally recyclable!
