Made from durable hand-blown borosilicate glass, this bottle includes one of our activated carbon filters and a stainless steel spiral to lock the carbon in place. It is protected by a protective sleeve made of recycled polyester. Its cover is a mixture of natural wood fibers and polypropylene. 100% waterproof and airtight. Water has never been so clear or tasted so clean. FILTER CARBON INCLUDED: The filter carbon is ready to use and the bottle comes with a stainless steel spiral to lock the Binchotan carbon in place. NATURAL WATER PURIFICATION: Activated filter carbon attracts ions of contaminants on the surface of the carbon, retains them, and at the same time releases minerals such as calcium, iron and magnesium into the water.
