The Black+Blum Active Binchotan Charcoal Filter provides a clean and refreshing drinking experience. This ultimate water filter draws on the ancestral Japanese technique of using Binchotan charcoal to make your tap water taste great. The charcoal is extremely porous and is full of tiny cavities directed in many directions, providing a high surface area within its small size.

Not only does the Binchotan charcoal rid your tap water of foul-smelling chemicals, it also infuses minerals such as calcium, iron, and magnesium - significantly enhancing its tasty and healthy characteristics. Intended for everyday usage, the efficiency of this product lasts up to three months when used with our 'eau good' bottle and filled up once a day. Refill lifespans are easily activated simply by boiling it in water. Step up your drinking game with Black+Blum’s Active Binchotan Charcoal Filter for an incredible pure-tasting hydration experience!
