Soma filters are designed and tested with sustainability and performance in mind, with each filter providing two months of clean drinking water. Through the power of activated coconut shell carbon and charcoal, the Soma filter protects your water from Chlorine, Mercury, Zinc, Cadmium, Copper, and other unwanted tastes or odors. Soma filters are made from 60% plant-based and renewable materials, which means a lower carbon footprint. Can be used with the 10-Cup Water Pitcher, 6-Cup Water Pitcher and the 6-Cup Glass Carafe. We donate to charity: water with every purchase you make. Let’s make a change together.
