Product review (5 stars): I just recently installed a Perfect Water Technologies
I have used these same filters for the last few years I've had my Kenmore/LG refrigerator. I just recently installed a Perfect Water Technologies, Hydroperfection reverse osmosis undersink water filtration system. This is the first time I've had enough water pressure coming out of the RO system to run to the refrigerator. So, this may be the last of these filters I'll need for a while since the RO unit is so far superior to the refrigerator filter. Such good water and ice out of my refrigerator now!
