Binchotan (Japanese Oak) activated charcoal is the highest grade of charcoal. These charcoals are from the Kishu region of Japan.
Excellent natural filtration properties that help reduce odor and hardness from water, and purify for great-tasting drinking water. Filtering time is 3-4 hours.
4 sticks are included in one package; Use 1 stick for a personal water bottle and use 2 sticks for a carafe. 1 stick can filter up to 1 L (33.8 oz) of water.
Each stick is approximately 2cm (0.8in) in diameter and 10cm (4in) in length. As this is a natural product, size and shape may vary.
Reactivate charcoal every two weeks by boiling for 10 minutes and letting dry.
