    I purchased this based on the system capabilities and design. I specifically liked the fact it reintroduces desired minerals back into the treated water. Taste of the water is excellent and the function and capacity of the system are top notch.

    Fantastic system compared to my previous one. The quality, taste, space savings are top of the line. I know my water bill will be less with this unit because it doesn’t use as much when it is purging. So happy with system.

    The system was easy to set up and fits well under our kitchen sink. We’ve been enjoying it for about two months now and the water tastes great! The faucet also works great and we’ve learned to convert cups to ozs, and change the setting on the faucet to measure water for tea!
