Product review (5 stars): A lot of people tell you a filter is good or bad
A lot of people tell you a filter is good or bad.  If bad they explain why, if good very little to say how or why.

So here is my experience.  Original GE filter was well past is replace date.  Noticed ice production going WAY down.  I found these filters and tried them.  My ice production increased dramatically, no wonder since the old filter was so far past is serviceable life.

Used the two filters over the course of 2 years.  I later did did not want to buy a two pack, so I tried another aftermarket brand.
That filter did not produce as much ice and did not last a year.  I went back to Waterdrop.

Are these the best on Amazon?  I honestly don't know as I have not tried them all.  When I find something that works I stop looking.

These filters have excellent chlorine removal.
High flow rate
Hight yield (gallons that will be processed before changing the filter)
It comes with a monthly labels so you know when to change the filter.  (I don't wait for the fridge to tell me the filter needed changed last month).  I change them every 6 months.
