Binchotan Active Charcoal Water Filter x4 refills (Active Charcoal Water Filter Pack of 4)

The 4-Pack Charcoal contains exactly what its packaging says – a 4-pack of Binchotan Charcoal Sticks. The entire 4-pack provides the equivalent of 2 years of filtration. Each filter stick is individually vacuum packed in recyclable plastic for immediate use. Use your Binchotan directly after opening the case for 3 months, then recharge it by boiling it for 10 minutes, let it dry and then you can reuse it for 3 more months of filtration.
