Well I don't know if water can be tasty, but this water filter claims to give you a tasty water source. It sits on your counter and uses about 8 steps to put your water into its natural form. I also don't know if you really want water in its "natural" form because it would probably be fairly infected with bacteria. However, this filter is designed to give its users mineralized and alkaline water.

The maximum amount of water that you can put through this filter in an entire day is 5 gallons. This should be plenty for most normal families or individuals. It does take some time for regular water to work its way through, which leads me to believe it is doing something good. Since water is a major part of everybody's health, I would say it is worth an investment to try and provide healthy water to you and your family.
