We've been zero waste since 2016 & these are what we use to prevent us from buying bottled water.  We've driven cross country twice since 2016, and with these we still didn't need to buy bottled water, so yes they do work.  If you've been in our store, you've probably seen these in the bottom of Boss Witch's water jar too.  Adding bamboo charcoal to your drinking water will help remove impurities and improve taste.  Harvested in Japan to maintain forest health & then carbonized at 800 C for Miyabi.  This size is for narrow mouthed containers & will filter 1 L of water at a time for about a month.

1. Rinse, boil for 5 minutes, dry off.
2. Add to 1L of tap water. We recommend 5 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.

HOW THEY WORK:  Bamboo charcoal's porous surface area adsorbs tap water and airborne impurities.  When 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.

RIP  At end of life throw your used charcoal into the compost, garden, or potted plant to add vital nutrients to the soil.
