Product review (3 stars): Does not remove fluoride!
The product does make the water taste better but upon more research (once it arrived) we realized it does not remove fluoride or other  contaminants as well as the original filter.  This would not have been an issue when we had well water (it was tested regularly) but now that we are in a city that adds fluoride, it's unacceptable for us.  The filter fits well and appears to be doing its job.  I recommend this cheaper alternative as long it provides the level of filtration you need.
