Product review (5 stars): The WaterSentinel has Been Accepted in our Home
The WaterSentinel is an economical alternative to our original refrigerator filter, the GE SmartWater MWF. The GE MWF was $40 at our local Lowe's compared to the WaterSentinel at $25!  We read the reviews, compared the fine prints and decided to give it a go. So, the instructions say to install the filter and then run water through it for 5 minutes. Well, we only filled up about 10 huge tumblers full of water and the water tasted BLECHHH! BUT...after about 10 more tumblers, it tasted crystal clean!!  So when they say, "Run it for 5 minutes", then DO IT!! Bottom Line: I'll be getting these again, as long as they are reasonably priced.  Thanks WaterSentinel and Amazon.
