Water nourishes all beings; the existence of all depends on water. It is no longer a luxury to have quality water at your disposal whether at work, at home or on a trip. The JIA Inc. Bamboo Charcoal filter Bottle features a bamboo charcoal filter core. When immersed in water, it will balance the pH value, purify impurities and soften the water to make it taste even better. The bottle features a double-walled vacuumed insulated stainless steel body and a leak-proof lid to keep your water at your desired temperature for up to six hours.
