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.

They wrote a buying guide for your next water filter:

... "Brita" filters were found to remove around 55% of PFOA, whereas "ZeroWater" filters remove more than 95%. I.e. "Brita" filters leave 9x more stuff in the water. The performance difference is similar for other unwanted stuff, like lead.
