Undersink Drinking Water Filters

Undersink drinking water filters by DuPont help make drinking water safer for your family.  With improved taste and greater clarity, you’ll find better flavor in foods and beverages when they are made with filtered water.

Our QuickTwist™ Water Filters are self-contained, proprietary systems. They are designed to fit DuPont™ Quick Twist Filter Cartridges only, and ensure easy, no-spill cartridge replacement.

Many of our other filters and systems are “universal” and are designed to fit most other brands of undersink water filters.
