The science behind how KURO-Bō Activated Charcoal works…

In creating KURO-Bō Activated Charcoal, it is the carbonisation process – and enlargement of the hardwood’s millions of internal pores – that actually enables the KURO-Bō stick to do what it does, namely: attract positively-charged toxins and metals (like chlorine, lead and mercury) and attach those toxins to itself on a microscopic level, removing them from the water.

This process is known as adsorption and it’s what makes your ordinary tap water taste so much cleaner and more delicious.

According to scientific sources, a single gram of activated charcoal can have a surface area of up to 1500m². To put this into perspective, a tennis court surface is, on average, 260m²! That’s why it is able to adsorb as many toxins as it does.

However, each KURO-Bō stick does reach a saturation point, which is why, after three months it needs to be recycled and replaced. During the monthly reactivations, the adsorbed impurities are not released back into the tap water, nor when the KURO-Bō stick is recycled. Instead the boiling process helps to keep the KURO-Bō stick’s pores open, as well as its surface area at its maximum capacity for adsorption.

KURO-Bō Activated Charcoal has been put through a range of scientific tests to evaluate its capacity for toxin, chemical and bacteria adsorption and removal, as well as its ability to balance pH and enrich ordinary tap water with beneficial minerals – all with significant and exciting results.
