The Japanese have been doing it for centuries - using a stick of charcoal to purify drinking water.
The charcoal stick water filter comes ultra-sonic cleaned and ready to use, all you need to do is fill your bottle with drinking tap water and enjoy great tasting water.
The sticks have a total lifespan of 6 months each, as its effectiveness decreases all you must do is boil it for 10 minutes to rejuvenate.
The activated charcoal water filter attracts the ions of contaminants to the surface of the carbon, and at the same time releases minerals such as calcium, iron and magnesium back into the water.
The charcoal water filter sticks are suitable for a bottle, carafe or jug.
