Eau Good, Water Purifier, Drink Bottle

Water Drink Bottles

The unique Eau Good filter drink bottle combines a reusable stylish bottle with a Binchotan active charcoal which has been Japan as a water purifier and softener since the 17th century. The filter reduces chlorine, mineralises the water and balances the pH. Since the active charcoal filter passively sits in the water with this design, best results are obtained from leaving the filter in overnight. The bottle itself is reusable and the combination has been created with the intention of improving water taste thereby discouraging just buying bottled water.

By placing the charcoal at the base of our 800ml eau good water bottle, this ensures that the water is constantly in contact with the charcoal allowing absorption through its small pores to efficiently purify the water. Each binchotan charcoal lasts for 6 months – after which it provides many secondary uses. Replacement charcoals are also available here.


  • Capacity: 6 month Life
  • Length: 12.5 cm
  • Diameter: 1.5-2 cm

Made to Fit: Eau Good 800ml Plastic Drink Bottle (sold separately)

May also be tossed into other reusable drink bottles, like glass or stainless steel, but should preferably be somehow locked into place so the charcoal doesn’t float to the top in order to maintain ease of drinking.

Can also be tossed into a pitcher or large bottle of water in the refrigerator to improve water taste.
