About Bamboo Charcoal Fiber

Keywords to Clean & Restful Nights: Antibacterial & Purify

Bamboo charcoal, also known as 'Black Diamond,' in Japan is one of the most multi-purpose substances that can be found in household products, beauty products, textile bedding, and even food.


The secret to bamboo charcoal’s antibacterial function falls behind an antimicrobial bio-agent found in bamboo called 'Bamboo Kun'. Our bamboo charcoal fiber is certified by SGS, that the fiber is able to prevent the growth of common bacteria such as E. Coli and Staphylococcus Aureus.

SGS is an international inspection agency based in Switzerland which provides inspection, verification, testing, and certification service.


Bamboo charcoal contains millions of pores, allowing it to absorb and degrade certain toxins, odors, and allergens.   

Bamboo Charcoal Fiber as Duvet Insert  

 After absorbing body temperature, bamboo charcoal will emit far infrared rays which help to improve micro-circulation and provides great insulation.
