    KURO-Bō is the ONLY scientifically-proven plastic-free water filter currently on the market. Convenient and easy to use, one stick will give you naturally purified water for 3 months + in a container holding up to 3L of water

    Some of the Benefits of using a KURO-Bō Filter

    • 100% natural, eco-friendly and plastic-free. 
    • Versatile and easy to use. 
    • Reusable daily for three months plus.
    • Scientifically proven to remove chemicals and heavy metals from ordinary tap water, such as chlorine, lead, aluminium, copper, iron, mercury and manganese. 
    • Enriches water with beneficial minerals, like magnesium and calcium. 
    • Scientifically proven to remove E. coli (at 99 CFU per 100ml). 
    • Neutralises an acidic pH. 
    • Improves the taste and odour of normal tap water. 
    • Add one KURO-Bō stick to any container up to 3 litres. For greater volumes, simply add more sticks.
    • 100% of the packaging is recyclable or biodegradable.  The charcoal filter is stored in a certified compostable corn starch bag
    • Recyclable in a number of innovative and eco-friendly ways (see below)


    How To Use

    • Remove your KURO-Bō stick from its corn starch packaging and activate it by boiling in water for 10 minutes.
    • Remove from the water and cool. 
    • Fill your water container (ideally glass, ceramic or stainless steel) with tap water (up to 3L) and insert a single KURO-Bō stick. 
    • The KURO-Bō stick will start working immediately, although ideally allow to filter for 4 – 6 hours, or overnight, at room temperature or in the fridge. 
    • After one month of daily use, boil your KURO-Bō stick for 10 minutes to reactivate it. Remove and allow it to cool, and then simply reuse. 
    • After two months of daily use*, reactivate your KURO-Bō stick again, allow it to cool and reuse as before. 
    • If your water doesn’t taste as clean and refreshing as it should at any stage, it likely means it just needs a little boost! In the first and second month, just try boiling your stick again for 5 minutes to open the pores again. After three months, it likely means it’s time to recycle and replace! 


    *The lifetime of each KURO-Bō activated charcoal stick depends on the water quality and daily volumes of water being purified. For greater volumes of water, simply add additional KURO-Bō sticks.

    • Keep your vegetables fresher for longer. 
    • Remineralise and balance the pH levels of your soil.

  • How Is It Made?

    How Is It Made?

    KURO-Bō activated charcoal (Binchotan) is created through an ancient Japanese technique where high quality hardwood is baked in a kiln, at temperatures of up to 1200ºC, until it becomes carbonised. 

    Through this process KURO-Bō activated charcoal becomes a highly porous natural filter and, when placed in water, naturally adsorbs and removes toxins, chemicals and bacteria, while balancing an acidic pH and enriching it with beneficial minerals – turning ordinary tap water into mineral water, with a delicious and more refreshing taste. 

    The KURO-Bō Activated Charcoal is made using an indigenous hardwood from Laos, and the branches are harvested from forests that are carefully maintained and managed by experts.
