Don't underestimate the power of these charcoal bits. Binchotan charcoal is made of 100% Ubame oak, and captures moisture from the air, effectively deodorizing your home. The small chips work wonders in bathrooms, basements, and other rooms with high humidity, preventing indoor mold as well as mildew growth. You can also use them in water: their purifying qualities extend there too, pulling any imperfections out of your H2O.
