Black+Blum Active Charcoal Water Filter Coil

The Black+Blum active charcoal water filter is a natural charcoal filter with locking coil that turns any standard bottle into a filter bottle.

Using the traditional Japanese Binchotan method, the charcoal helps remove chlorine and add minerals for cleaner-tasting water on the go. The high-quality stainless steel coil holds it in place through daily refills.
