I decided it was time to change it because the water was flowing out in a trickle.  I then bought this 2 pack in March, and both filters are clearly defective.  Upon initial installation, both produced water at the normal, high flow rate.  Then, the first filter I installed died in just 2 months.  Thinking it was defective, I installed the second one, and it didn't even last one month.  The failure mechanism is: the water flow rate goes from the normal, high flow rate that will fill a 16oz water bottle up in 5-10 seconds, to a trickle where it takes 1-2 minutes to fill up the same bottle.  See the attached video; this is what it looked like when all three of these filters failed.  Thinking it could my refrigerator freezing the filter, I removed the one in the refrigerator and let it sit on my counter over night; after reinstalling it, the flow rate was still a trickle.  My refrigerator isn't the problem; the OEM filters never had this issue.  There's something wrong with this brand of filters.
