This Organic Cotton Mask with Bamboo Carbon is washable in cool water with mild, unscented detergent. The effectiveness of the bamboo carbon may last through washing approximately 60 times.

Bamboo charcoal contains many pores and gaps in its structure, making it excellent for adsorption, electromagnetic shielding, and infrared emitting. Besides adsorption, bamboo charcoal is also known to be antibacterial and anti-fungal. The antibacterial and deodorizing benefits of bamboo comes from the nano particles of bamboo charcoal and not chemicals, making the fabric much more acceptable to chemically sensitive people.
