How does it work?

Connect the filter under your sink and let the system go to work. Once water is flowing, all pathogens are destroyed at a molecular level. It's as simple as that!


It tastes good too!

Beyond pure water, a sustainable coconut shell filter (GAC) has been added in the under sink filter as a bonus for your taste buds. GAC removes chlorine, organic contaminants and odors, and PFAS making it the best tasting water around.
