Our most efficient reverse osmosis filtration system yet.

Capella combines technology and science to deliver a reverse osmosis water filtration system that stands out among the rest. It’s certified by the Water Quality Association (WQA) to reduce over 86 contaminants found in drinking water, including microplastics, DEET, flame retardants, prescription drugs, PFAS “forever chemicals,” and more. The end result? Safer water, straight from your sink.

Traditional reverse osmosis systems can waste up to 20 gallons of wastewater for every gallon of clean water that they provide. We knew we had to do better. That’s why Capella features a 1:1 ratio of wastewater to filtered water, making it one of the most efficient and effective reverse osmosis systems on the market. It's healthier hydration for you—and for the planet, too.
