Collection: Activated Charcoal Filters

Scientifically-proven, KURO-Bō Activated Charcoal Sticks and Koins are a completely plastic-free, sustainable and recyclable water purification solution. The ultimate next generation of water filter – for home or for travel.  A single stick of KURO-Bō Charcoal provides 3+ months of daily cartridge-free and naturally purified water. The charcoal stick will purify up to 3L of water at a time, while the koins will purify up to 1L of water at a time. For greater volumes, simply add extra sticks or koins.

Activated charcoal, or Binchotan attracts and draws out positively-charged toxins (chemicals, heavy metals, E. coli) from your water, while depositing beneficial minerals and balancing an acidic pH.
