Sounds like they care about their customers enough to add a mechanism like that. I think a transparent filter with a sensing colored indicator would be a much better and more customer friendly solution though.

Other filters have a shitty digital timer on the pitcher lid last time I checked. It never worked well so I resorted to changing the Brita whenever it started tasting funny. Now I just buy artesian alkaline water. I feel much better.

Most of these filters suck. Better off making your own. Buy silver coil and NSF coconut carbon. Use a french press type device to push water through your silver assorted carbon. Easy! And you save plastic since you made the filter yourself :-)

When the third world revolts, this will be their rallying cry.
