This binchotan active charcoal filter is used to filter water by absorbing impurities such as chlorine, and adding minerals such as calcium. The charcoal filter is pre-washed and vacuum sealed, so it's ready for immediate use. Simply drop the charcoal into your water bottle, leave for 1 hour and enjoy your filtered water. Each charcoal will last for 6 months as a water filter. Then, they are recyclable and compostable and can be used around the home, such as a plant fertilizer, or, place in your shoes to deodorize!
