Bamboo charcoal water filters



Natural bamboo charcoal water filters made from high quality bamboo charcoal. The charcoal will absorb chlorine, chloramines and other impurities from tap water, mineralise it, and gives your water a lovely fresh taste. Super efficient thanks to the amazing porous properties of bamboo charcoal, it works just like a sponge!

No need for unsightly plastic jugs: simply place the charcoal pieces inside your water jug, fill with tap water one hour before drinking it. Made in Japan using clay kilns, an ancient tradition for filtering water used all around the world.

Sold in pack of 4 or 8 bamboo charcoal water filters. Each piece is approx. 5cm x 5cm. Use 3 to 4 pieces for a 1 litre jug of water. Boil before use, then keep for several months.

Bamboo charcoal is sustainable and leaves no waste. Take a look at our reusable water bottles in glass and metal which these bamboo charcoal filters can be used in and help yourself on the zero waste journey!
