Plastic-free water purification - the way it should be. The Japanese have been using Binchotan charcoal for centuries to purify water. No need for the disposable plastic casing typically used to hold charcoal granules as the charcoal stick is a natural absorber of impurities.
One stick of the large size Binchotan charcoal for pitcher lasts up to six months, purifying up to 2 litres / 0.5 gallons of water per day. Just let the stick sit in the water overnight for best results.
Binchotan charcoal is a unique charcoal exclusive to the forests of Wakayama, a province in southern Japan. The branches of holm oak trees are sustainably harvested then slowly fired in traditional kiln ovens over many days. Binchotan charcoal sticks naturally absorb toxins such as chlorine, lead, mercury, cadmium and copper from tap water and impart good minerals such as calcium, potassium, magnesium and phosphates to water.
Care and use: It is recommended that the stick be boiled in a shallow pan of water for 10 minutes every month or so to keep the exterior pores open and make it last longer.After four months, boil the charcoal stick again. If you don't see a profusion of bubbles circulating around the charcoal stick when it is returned to the water bottle and water is added, the stick has reached its capacity to absorb toxins. At that point it is ready to be composted in the garden or used as an odor absorber in the fridge.
Dimensions: Please note that exact dimensions are not available for the binchotan charcoal filters because each one is hand cut and the diameters and lengths vary quite a bit in size. Thus, weight is used as a constant as follows:
Small (Bottle): 20-30 grams / 0.7-1.1 ounces
Large (Pitcher): 44-55 grams / 1.6-1.9 ounces
Extra Large: 70-75 grams / 2.5-2.6 ounces
Materials: Made from branches of sustainably harvested Japanese holm oak trees - slowly kiln-baked for several days to produce charcoal.
Care Instructions: It is recommended that the stick be boiled in a shallow pan of water for 10 minutes every month or so to keep the exterior pores open and make it last longer. After four months, boil the charcoal stick again. If you don't see a profusion of bubbles circul.
