It works and it is sustainable.

I make my own kombucha. Boiled tap water killed my Scoby. Kuro-Bo filtered water did not! I think this pretty much sums up how well the filter works. It also looks beautiful and has no landfill impact. Fantastic product!

The first of their kind globally, and scientifically-proven, KURO-Bō Activated Charcoal Kōins are a completely plastic-free, sustainable and recyclable water purification solution.

With our online-only “Buy 4, get 1 Free” deal, up to four people can enjoy naturally purified water on the go every day, and get another 3+ MONTHS completely FREE.

Whether paired with our Gō-Ecō Glass Water Bottles (550ml or 1L) or your own reusable bottle, a whole pack (4-5 pieces) will purify up to 1L of water at a time.

Activated charcoal, or Binchotan attracts and draws out positively-charged toxins (chemicals, heavy metals, E. coli) from your water, while depositing beneficial minerals and balancing an acidic pH.
