Product review (4 stars): Cheap replacements don't do nearly as well at filtering
After trying some cheaper replacements, it is clear they just don't do the trick.  The water tasted funny, and after a couple of months you could see particles in the water from the filter!

Ordered these to see if it was a problem with our filter, our water, or something else.  It was definitely the cheap filter.  The water coming out of the fridge tastes great again, and NO floaties.  :)

-1 star for how expensive they are.
