Product review (5 stars): Great lower-cost replacement filter
I'm very pleased with this water filter.  It's much less expensive than the branded filter yet does just as fine a job.  The water tastes as fresh as it ever did with the Whirlpool-branded filter and flows just as freely.  I expect this to be my new "go to" replacement filter.  I had no problem whatsoever in inserting it - no leaks, etc.
