Harvested from the rapidly growing moso bamboo, bamboo charcoal is a naturally occurring porous structure with millions of microscopic holes pulling and absorbing odour and moisture from the air. Bamboo charcoal is natural, sustainable, reusable and recyclable. Due to non-toxic and eco-friendly attributes, bamboo charcoal is literally nature’s way of eliminating life’s stinky stuff! The Closet Deodorizer Set is completely unscented and eliminates odors instead of masking them. Simply hang the deodorizing & dehumidifying pouch in a closet to freshen it up.
