Kuro-Bo has created a new generation of water filter for the South African home. These activated charcoal koins are the first of their kind in Africa; a completely plastic-free, cartridge-free and recyclable water purification solution. Activated charcoal, or Binchotan, attracts and draws out positively-charged toxins from your water, while depositing beneficial minerals. Each charcoal koin lasts for up to 3 months.

  • Simple, cartridge-free charcoal filter design
  • Minimal & functional
  • Purifies ordinary tap water in a 100% eco-friendly way
  • Pair with Kuro-Bo's Go-Eco glass water bottle for 100% natural and portable filtered water
  • Removes bacteria (e.Coli), toxins & chemicals, including chlorine, lead & mercury
  • Balances the water’s pH level
  • Enriches every glass of water with minerals like calcium & magnesium
  • Improves the taste of your tap water
  • 1 pack of charcoal koins lasts up to 3 months
  • Koins & packaging are 100% recyclable
  • Charcoal also makes an excellent dehumidifier & deodoriser in damp areas of your home
  • Used charcoal can be repurposed as garden fertiliser


  • Remove the Kuro-Bo koins from their packaging & boil it in a shallow pan of tap water for 10 minutes.
  • Allow the charcoal to cool, then fill your water bottle (up to 1 litre) with tap water. Add the charcoal koins (4 -5 koins, depending on the weight of the charcoal).
  • For best results, allow the charcoal to rest for 3+ hours, although they start purifying immediately, either at room temperature or in the fridge.
  • After 1 month of daily use, reactivate your charcoal koins. Simply boil it again for 10 minutes, allow them to cool, and reuse as before. 
  • Repeat the reactivation again after 2 months of daily use.
  • The smaller volume will purify, mineralise and balance faster. 
  • After 3 months of daily use, recycle & replace the charcoal.

Love this! First time buyer, and I'll be coming back for more. We already filter our water, but I use these for my personal drinking water, an extra layer of filtering - and it makes the water taste so delicious I keep wanting more.

Great product. My husband also uses them at his office now for his water bottle. Makes room temp water taste much better he says.

Very happy with this product takes that weird taste out of the tap water.

A really great, easy to use water filter system! I wasn't sure how well it would work but I noticed the taste difference after filling up my first bottle. Cleaner tasting, metal free water. I bought the Kuro-bo 1L bottle to go with the koins. They were however, smaller than depicted and would probably fit through the neck of a normal glass consol bottle.

You can really taste the difference in your water! I'll definitely be ordering these again.

I must admit that I was dubious when I read about this product. Well, I'm a convert now. The water really is softer, smoother and tastier. This has been my best eco-buy for this year!

I cannot drink tap water directly from the tap anymore. I can instantly taste the difference. Also filters quicker than the sticks so perfect on the go. I use it with the Kuro-Bo 1 litre bottle and it’s ideal for my desk at work.

So happy with my 'coins' . I bought them for our holiday trip......we saved a fortune on bottled water and we're so happy with the taste of our coin filtered water......needless to say we are now using KURO-BO every day at home. Thank you for the amazing product

Our whole family uses KURO-Bo and we couldn't imagine living without it.

Great buy. Makes your water taste super clean and smooth. Love it. This is my second batch and will keep ordering most definitely.

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!

I am using it and the water tastes delicious!

For a long time, I have been using a water jug filter. Until I read about KUTO-Bo charcoal. I will always use this product now. My water tastes great and can feel it is doing wonders for my body. Love it!

so far its been great. We do use a filter for our main drinking water at home, but I use this in our drinking bottles when we travel! its been great

If I could give it 10 stars, I would. My water has never tasted to good. It is worth the cost. However, at the back of my mind I can't help but wonder over the environmental cost to making charcoal ...
