Product review (1 stars): Defective filter
Do not buy from this source.  These are defective filters. I replaced the old filter with the one I received from Amazon ( having done this many times before) and the new filter made a grinding motor sound and barely dripped water.  I re-installed several times with the same result.  I subsequently went to Home Depot and bought the same filter which installed and worked perfectly on the first try. They are selling defects.  Do not buy from this source.
