Product review (4 stars): Great Filter
About 2 months in filter still working great. I have a water softener and post filter, so the water going in is pretty decent, but this filter really does a great job doing the fine clean up work. Took a star off as the price seems a little high when compared to other water filters (thinking whole house filters).

Update: 10/12/16 While the filter did a great job was they were clogging at a fairly quick rate ~4 month, so I cut it open to see what was going on. Turns out the fridge was installed on the wrong cold water line (unfiltered and unsoftened) that is used for outdoor watering. We have really hard water and lots of sediment so the filter was really doing a great job and you can see all the rust that got captured in the pics.

Uploaded some pics of the used filter, purely self motivated. I got an off-brand filter in service now I want to see the difference been this and a filter that costs 1/2 as much. I don't know how to measure the porosity of the filter media, but here are some details on the construction:
Wall thickness ~3.75mm
Carbon core with filter paper overwarp - ~39mm
Core center - ~11mm dia
