Product review (1 stars): O ring problems and will cause your filter to leak
Purchased this 3 pack in September 2017.  Well, Im on my third filter hoping that it will last!  Seems the O ring becomes loose and this causes the filter to leak.  So thankful I had a plastic bin just below the filter to catch the water.  So Ill see how long this one lasts as it was installed 2 weeks ago.
