The Bamboo Charcoal Ring is a household product that combines activated bamboo charcoal with a base of different material shapes. The ring is made of activated charcoal, diatom mud, bentonite and a konjac sponge. The konjac sponge provides a three-dimensional shape and the loose porous structure. The shape enables greater contact with air with its increased surface area. Activated carbon, diatom mud and bentonite are absorbent materials that remove impurities, eliminate odor and absorb moisture.
