Product review (5 stars): Good filter - tastes fine
I've purchased a few of these filters (both the old blue and new white version) and they have always been great. The water tastes fresh and clean every time and seems to do well with filtering the typical bad tasting city water.

The filter mentions you are supposed to run about 4 gallons through it before drinking anything from it. I'm guessing some of the people complaining about the plastic taste are not flushing it properly. It takes a rather long time to flush 4 gallons through the filter by hand. I just run a small tube to the sink and use my shower curtain rod to hold the valve open while I kick back and relax. It takes about 10 and a half minutes for four gallons to run through it (pictured). I recommend calculating the flow rate of your fridge before attempting this method as I'm sure it is different per fridge.
