Product review (5 stars): Great price for original replacement filter.
I saved $10 by purchasing this replacement refrigerator filter through Aamzon.  I received the filter in good condition and it was easy to install.  Follow the included instructions carefully for purging the air out of the new filter.  My water dispenser valve stuck open until all the air was purged from the filter and water lines so I ended up with a small amount of water on the floor.  The valve acted like water pressure is required to help it close. A small pitcher (~2 qt.) rather than a drinking glass may be helpful when you purge the air to alleviate water spills if your valve happens to stick open as mine did.  I will probably buy my next replacement filter from Amazon.
