Product review (1 stars): Does not work consistently
I purchased a 3 pack (not from Amazon) for use in my GE Profile refrigerator.  The first one worked fine, but when it came time to replace it, the second one would not work.  After installing the second filter I received no water through the dispenser.

First I thought something was wrong with the water line.  I pulled out the fridge and checked water flow into the dispenser.  Water flow was good.  I then started thinking the water valve was broken, but it seemed curious to me that it failed exactly when I replaced the filter....so I tried putting the first Aqua Fresh filter back on.  But again, no water.

Before I started replacing valves, I wanted to completely rule out the filter as potential cause so I put the bypass plug into the filter holder and water began to flow again.

At this point I'm thinking it must be the filter.  I go to the local store plop down the the ridiculous sum of $43 for the GE brand filter, plug it in, and it works!  I then compared the Aqua Fresh filter side by side with the GE brand and found that the diameter and construction of the socket inside the Aqua Fresh filter is different than the GE.  The socket needs to be able to depress and hold a spring loaded valve underneath the filter holder in order for water to flow into the filter.  However, the Aqua Fresh filter sometimes will not completely depress and hold the valve open when mounted.  Some of them work, some of them don't.

Anyway, as much as I hate to admit it, I'm going to stick with the overpriced GE brand, seeking out the best deal I can get on Amazon.
