Product review (5 stars): Buy, prep properly and you won't be sorry!
I love the fact that I was able to save so much money on the water filters for my refrigerator. HOWEVER, as with a lot of things we buy, there are some steps of prep work to get these functioning properly. As explained to me by the manufacturer, you need to run 2.5 to 3 gallons of water through the filter to flush out the carbon block residue inherent in the manufacturing process. I used my "flushing" water for the plants. This also equalized the pressure in the pipes and it no longer drips. I am a happy camper.
