With the iCE water filtration device you can more accurately monitor your drinking water, giving you confidence about its quality. Rather than relying on the imprecise method of using a timer to tell you when to replace the filter, iCE monitors the level of total dissolved solids, a surefire indication of when the filter has lost its effectiveness.Designed by: KOHLER Shanghai studio - Electronics teamContact: river.cheng@kohler.com.cn
