Charcoal Water Filter

Purify your water without the waste with this Kishu Charcoal water filter. Simply drop your charcoal stick in your favorite bottle, carafe, or pitcher and let it work its magic. Charcoal sticks are reusable for up to 4 months with easy maintenance.

Kishu Charcoal has been found to be effective at reducing: LEAD, MERCURY, COPPER, ALUMINUM, URANIUM, and MOLYBDENUM to name a handful of those we tested. In addition, Kishu Charcoal imparts three minerals: Calcium, Magnesium and Potassium.

Kishu Charcoal is ready to use upon opening the package. Simply place in any pitcher or water bottle and add tap water. Kishu begins adsorbing impurities immediately, while also imparting healthy minerals like calcium and magnesium. These give your water a delicious, clean taste.

First Use:
While Kishu begins working immediately bonding with toxins, for optimal adsorption:
Kishu To Go – approximately 16 oz of water/ 1 hour
Kishu Regular – approximately 2 quarts of water/ 4 hours
Kishu X-Large – approximately 3 gallons of water/ 24 hours.

Maintenance:
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 5 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.

Kishu is a finely crafted form of activated charcoal also called activated carbon. By heating wood to an extremely high temperature, usually in a kiln, and slowly depriving it of oxygen, the wood becomes carbonized. Kishu Charcoal is 97% pure carbon.

This pure form of carbon readily adsorbs or bonds with toxins, principally metals, at the molecular level. Kishu Charcoal has been found to be effective at reducing: LEAD, MERCURY, COPPER, ALUMINUM, URANIUM, and MOLYBDENUM to name a handful of those we tested.

In addition, Kishu Charcoal imparts three minerals: Calcium, Magnesium and Potassium.

Kishu Charcoal has great secondary uses: absorbing odors in the refrigerator (better than baking soda!) or mixed into your garden soil where it will help improve water absorption.
