Serious Water Filtration: The ESSENTIAL is the first drinking water system designed to protect you and your family from the modern issues with water contamination. Better tasting water can be achieved simply and cheaply by letting water sit out, or by using an inexpensive carafe or faucet attachment. However, none of the contaminants have actually been removed – chlorine byproducts, chloramine, pesticides, dissolved lead, and other contaminants are still present in the water. The ESSENTIAL is serious water filtration for people who desire truly clean, truly healthy water without the water waste or flat taste of reverse osmosis.

Hassle-Free Convenience: Enjoy clean, delicious water right at your kitchen or bathroom sink at any time with zero hassle.

Easy to Install & Use: Installs easily at any sink. Complete installation information comes with every unit and is available online.

No More Wasted Money & No More Plastic Bottles: Replace expensive and wasteful bottled water with the healthy, filtered water from your ESSENTIAL filtered sink. You will save at least $500 every year in bottled water expenses, and prevent plastic waste in our landfills and oceans. Simply fill up your reusable glass or metal bottle at your sink and go!

*WELL WATER WARNING Well water is required to have independent, complete and proper testing of your well water to determine the proper course of action in order to specify the correct system(s).
