Product Details

Kishu charcoal water filters are all natural and plastic free, providing you fresh, pure water without waste. The "To-Go" is designed to be used and reused in travel bottles. Using ancient techniques, Kishu is made by Japanese artisans from sustainably harvested holm oak trees, slowly heated in handmade kilns to produce the finest actived charcoal. The filter absorbs toxins, impurities and heavy metals from water while imparting calcium and magnesium. Each filter is good for 4 months, only needing to be boiled once a month to be renewed. At the end of its life, Kishu filters can be used in the refrigerator to absorb odors or crushed and added to garden soil to help improve water absorption.

How does it work? Activated charcoal naturally bonds with toxins. Once this molecular bonding occurs, the toxins will remain attached. The toxins that have been removed will not leach back into the water.  Kishu Charcoal has been tested to be effective at reducing: LEAD, MERCURY, COPPER, ALUMINUM, URANIUM, and MOLYBDENUM to name a handful of those tested.

Use: Place in any water bottle, add cool water.   Kishu begins working immediately.* It does not need to be removed.  Kishu Charcoal should be boiled once per month to keep its pores open. Simply place in a shallow pan of water and bring to a boil for 10 minutes. Allow to dry for 30 minutes before reusing. While a small amount of flaking may occur, the stick will stay completely intact; Kishu will NEVER deteriorate. After four months, Kishu should be replaced. Please use the handy boiling schedule, located inside the package label, to keep track of your Kishu stick’s life.

size: approximately 3"

* Kishu begins absorbing toxins immediately, however (using approx 16 oz water) time for optimal absortion is 1-2 hours.

Kishu Charcoal
Kishu Charcoal was born in 2011 as an alternative to plastic water filters. Determined to find an eco-friendly, plastic-free way to filter tap water, we came across a material used in Japan for thousands of years. Made by artisans, using traditional methods and handmade kilns, Kishu Charcoal is brought to life from sustainably harvested oak branches slowly carbonized to 1000 degrees. After a number of days, a beautiful and glass-like activated charcoal emerges. Kishu Charcoal is… …the only completely plastic-free water filter. …made from the finest Japanese activated charcoal. …individually hand cut — every stick is different. …produces the most delicious tasting tap water.
