Product review (1 stars): Defective, no water flows through filter
I bought this water filter for my Whirlpool refrigerator because it is supposed to be UKF8001 compatible.  However, it does not work.  I followed the instructions on the packaging to submerge the water filter in cold water for at least 15 minutes.  I also carefully followed the instructions not to removed the O seal and when installing the unit to push it hard and to twist it clockwise hard.  Despite this, water would not flow through the filter, even though my refrigerator is counting ounces like water is passing through the dispenser.  I replaced the old filter back, water flows through, I replace with the new unit, water does not pass through.

I am very disappointed in this unit.  i wanted to try and love it as it is supposed to greener.  Too bad!
