Miyabi Bamboo Charcoal Water Filters - 3 pieces

Adding bamboo charcoal to your drinking water will help remove impurities and improve taste.
No more plastic bottles or filters.
No more waste. Throw your used charcoal into the compost, garden and potted plants to reduce trash and add vital nutrients to the soil.

Three simple steps:
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! Your charcoal should last around 4 weeks depending on quality of your tap water.

Bamboo charcoal's porous surface area adsorbs tap water and airborne impurities. If carbonized at high heat, 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 adsorptive power and contains many mineral components (especially magnesium, 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.
