Black+Blum EAU Good Water Bottle Features Ancient Japanese Style Charcoal

In place of a complicated filtration system in the cap, the new eau good water bottle from London-based designers black + blum caught my eye. It simply features a stick of binchotan active charcoal, a material that has been used to purify water since 17th century Japan. The natural filter is said to reduce chlorine, mineralize the water, and balance the pH.

According to DesignBloom, the biochar acts as a lock-in-place water filter. This ancient Japanese-style charcoal is made from wood that is sustainably sourced and fired inside a kiln for a long time at a low temperature. When it reaches 1,000 degrees Celsius, the charred specimens coated with an earthen powder of sand and ash, turning them immediately white. The combined heating and rapid cooling process removes any remaining bark from the objects to reveal  a smooth surface and hard composition.

The binchotan charcoal is incredibly porous and because it’s an active carbon, full of ions that attract and hold contaminants to its surface. According to B+B, it’s also able to release minerals such as calcium, iron, and magnesium back into the water which enhances its taste and health benefits.

Everything about this bottle is elegant and efficient. My only complaint is that instead of making it with glass, Black + Blum chose to form the bottle from Tritan, a controversial BPA-free plastic.
