Everything in your kitchen should be beautiful, and the Soma Glass Carafe Hourglass Water Filter is no exception. With a strikingly simple hourglass design, this carafe filters out the bad stuff. In fact, this glass pitcher removes chlorine, zinc, mercury, and copper from your drinking water. While the exterior consists of durable borosilicate glass, the inner filter is made of primarily plant-based, renewable BPA-free plastic. The glass water filter has a clean, minimalist look so it blends in on your dining room table, in your office, or in your kitchen. Plus, it’s easy for anyone to pour from the Glass Carafe when holding it by the thin hourglass neck. The small inner filter works to clean up to 40 gallons of water, at which point you can replace it with your automatic shipment. Simply hold the carafe under your faucet, and its door will open for you to refill it.
