The original cold & hot water cooler
The water cooler that started it all for us. The Optimum 3i is a sweet combination of streamlined design and leading-edge water purification.
To this day, the Optimum 3i is trusted to deliver the purest, freshest-tasting water for small to medium-sized spaces. Featuring a large, 3-gallon cold tank, it purifies and holds more water than the Optimum 2i, making it an ideal source for fresh-tasting water in larger workspaces. It keeps your office hydrated and healthy. For purification, the 3i uses a 4-stage filtration process that removes sediment, chlorine, and bacteria while oxygenating water for the freshest test possible.
The result is a continuous source of clean, healthy, delicious water.
