The Eau Good Bottle from Black+Blum uses a traditional Japanese Binchotan charcoal to make your tap water taste amazing. Binchotan active charcoal has been used in Japan for its natural ability to remove contaminants to purify water since the 17th century. It naturally filters tap water, adding good minerals such as calcium and balancing the pH levels. It absorbs unpleasant tastes and odours such as chlorine and softens water. Simply drop and lock the charcoal in the bottle, fill with tap water and experience the best tasting tap water. With a retro design that utilises a cork stopper and stainless steel lock wire, the plastic bottle has an attractive and ergonomic shape that harks back to old Victorian bottles. When the binchotan is used once a day it should last for three months. It can then be recharged by simply boiling it in water for ten minutes and leaving to dry in sunlight which should then last for a further three months. Eastman Tritan/Cork/Stainless Steel/Silicon Includes 1 x Binchotan active charcoal filter (6 months’ life) Dimensions: H: 24cm x Dia: 8.5cm. Capacity: 800ml.
