Ready-to-use replacement activated carbon, for all types of drinking vessels. Simply fill any bottle/carafe with (drinking) tap water and wait until the charcoal has filtered contaminants out of the water. It is ideal to let it draw overnight, but you will taste the difference after just one hour.

It may seem counterproductive to purify drinking water with a charcoal stick, but the Japanese have been doing it for centuries. Binchotan is an activated carbon obtained from tree trunks and is known for its ability to soften water, add good minerals and absorb unwanted tastes and odours such as chlorine.

Over time, there will be a decrease in the effectiveness of the filter on the taste of water. In this case, add it to boiling water for 10 minutes to wash out the impurities.

All in all, this filter lasts up to six months.
