The first of their kind in Africa, 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, you can enjoy up to 12 months of cartridge free and naturally purified water on the go, and get another 3 MONTHS completely FREE!

Whether paired with our Gō-Ecō Glass Water Bottle or your own reusable bottle, a whole pack (4-5 pieces) will purify 1L of water at a time. For 500ml, add half the Kōins.

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.

    Clean water for a family on the move! Our family travel a fair amount. Whether it be around South Africa or elsewhere in the world. We simply love this product, we have finally eliminated the need for purchasing water in plastic bottles. We take 4 or 5 stainless steel bottles and alternate them while we are away, with the Koins inside constantly cleaning the water. Best tasting water and best for you. Its seriously a win win! – review from Faithful To Nature
