The smart display tracking each filter’s life was super helpful, so I never worried about forgetting to change them.

Long-Term Performance

After using the Waken Electric C11S for several weeks, it continued to perform reliably. The water quality stayed consistently high, and the system showed no signs of slowing down. The filters lasted as expected, and the waste tank reminder kept everything running smoothly without any issues. Overall, it felt like a smart investment for clean, healthy water whether I’m at home or even when I took it along to my RV.
