Not at this time. AquaTru was designed to be easy to use, so we chose approximately 1 gallon of water to make it easy to lift and move, say to the refrigerator, or wherever you decide to dispense your water from. The good news is that since AquaTru purifies so quickly, you can easily make multiple gallons per day.
In fact, one helpful tip so you have extra water on hand is to empty and refill your tap water tank as soon as one gallon is filtered. This way your AquaTru will immediately start filtering and replenishing your clean tank any time you dispense water from it. See Helpful Tips video here.
Additionally, you can also purchase a second clean water container so that water is always being filtered on the unit while the other container is being used for pouring or dispensing.
