Filters and fortifies.

Replaces the filter on your BU Water bottle.

Natural bamboo charcoal is a powerful purifier which refreshes tap water. It absorbs unwanted tastes and odours, such as chlorine.

It’s rich in minerals – including magnesium, potassium and calcium. These are released as it filters, to enrich your water.

Filtering water with bamboo charcoal dates back to ancient Japan where, using traditional methods, the bamboo is placed in a kiln and transformed into activated charcoal.

  • Releases minerals: Enriches your water.
  • Removes impurities: Absorbs unwanted chemicals and tastes.
  • Eco-friendly: Made from high-quality, sustainable bamboo.


Replace the filter every three months (based on filling your BU Water bottle twice a day).
