Purchased OnePurify 2 Pack filters to replace GE MWF Smart Filter. Followed instruction and drained the water in one quart increments up to 1.5 gallons.  Initially, black chunks came out in a clear water for the first quart of the drained water. On the second round of draining the water, I noticed water turned black (perhaps fine powders of charcoil?).  Water was still black for the 3rd quarts of water. On the 4th quarts and the rest, water was clear. I noticed that water flowed out very quickly when compared to the OEM GE MWF Smart Filter. Fast water flow makes me wonder if it's the same filtration steps as GE. I have never experienced black particles and balck water before when I purchased GE filters for the past 10 years.  I am not sure if black water is a common thing to see for generic filters but if it is, I am going to stick with original GE MWF filter to have assurance of drinking a purified water.  I don't think OnePurify water filters have been properly tested in USA.
