Product review (1 stars): Horrible replacement filters.
Ordered a two pack a few months ago. First filter was fine. Replaced with second from pack after 3 months and no water flow. Like the filter is clogged. Amazon was nice enough to replace with another two pack which I received today. Both filters in this pack have nearly zero water flow. Trying to flush 4 gallons thru the filter would take four hours. Looking for the old Pur filters. Never had an issue with them.

5/4/16  We just discovered the housing on our fridge is bad.  That was probably the cause of the filters not working properly.  Not sure until we try them again.
