Avoid plastic by filtering your drinking water at home and on the go with bamboo charcoal. Most filters include plastic and are difficult to recycle. Once the charcoal is no longer useable, add it to your compost or garden where it adds nutrients to the soil. And continue to say no to single-use plastic water bottles!
3-month supply (approximately 3 ounces per package)
**1 ounce = about 3-4 pieces. This should last about a month (depending on the quality of your tap water)
How to Use
1. Rinse, boil for 5 minutes, and dry in the sun.
2. Add to a one-liter of tap water. We recommend 3 pieces per liter of water. Add more pieces for larger containers.
3. Let stand for 1 hour and drink!
Does it work?
Bamboo charcoal adsorbs tap water impurities as they attach to the porous surface area within the bamboo charcoal.
Tests indicate that bamboo charcoal removes chlorine, chloride, phosphorus, ammonia, toluene (alcohol), nitrogen, chloramine (ammonia and chlorine compound added to water to kill pathogens), and even toxins like pesticides that can seep into tap water.
Bamboo charcoal adsorbs solids and gases, but not pathogens, so we don't recommend relying on bamboo charcoal to filter creek water while hiking.
Compared to wooden charcoal, bamboo charcoal has high absorptive power and contains many mineral components (especially potassium, calcium and silicic acid).
The surface area of bamboo charcoal is 300 square meter per gram and the adsorption power is ten times that of wooden charcoal. A test conducted by the Division of Forest Management (Kagoshima Prefecture, Japan) in 2004, found that the pH value of bamboo charcoal-purified water changes from acidic to alkaline when bamboo is carbonized at a high heat. The study found that the surface area for volatile organic compound (VOC) adsorption is maximized at 800 degrees Celsius, which is the heat that we use for carbonizing Miyabi Bamboo Charcoal. In addition, the study stated that the "best" carbonizing temperature for reducing residual chlorine in tap water was 800 degrees Celsius.
