Bamboo charcoal helps to purify water, eliminate residual chlorine and chlorides as well as smells and organic impurities.
To use, rinse with water, then boil for 10 minutes to disinfect. To prolong the purifying effects repeat the process every 10 days or so and change to a new piece after 3 months.
Take 100g of bamboo charcoal wrapped in paper or cloth and place on a shoe rack, in a chest of drawers, a car or cat litter. It will absorb odours, keep the space fresh and help to prevent moth damage. Wash with water and dry once a month. Typically lasts 3-6 months.
