Product review (5 stars): Perfectly functional water filter
I'm not sure it is accurate to say that I "LOVE" my water filter, but if it is possible to love a filter, these Water Sentinel WSS-1 refrigerator filters could be loved.  I have used this brand for 3 years now.  I only change mine once a year, but I have not run across a problem yet.  Just make sure you are purchasing the proper style for your fridge.  The price is very reasonable compared to the name brands.  My palate is not especially discriminating, but it seems the water tastes perfectly good, and the pressure is completely normal.
