Product review (3 stars): I doubt it filters as well as OEM
I have replaced my filter a few times and this is the first time I have used a third-party filter.  It is also the first time after replacing it that the water flow from my dispenser has gone up significantly.  I can only attribute that to a lack of filtering or lack of restrictor to force longer contact with the charcoal to better "clean" the water.  So I have t assume it is not filtering as well.  However when dealing with microscopic particulate it's hard to prove.
