Product review (4 stars): not much to annoying me but I notice if I let the water ...
This unit fit very well, and about third of price to the Pur filter I was using.
After using it for a few weeks, I started to taste something, not much to annoying me but I notice if I let the water sit in a mug for a few hours, it has a trace of taste in it. I can't describe what it taste like but its not enough to bother me at this point.

Will continue to use this filter, but I might end up back to Pur filter after this.
