Product review (5 stars): Removes chlorine effectively
I've been in the water industry for a long time now and I sell many different types of water lfiltration equipment.  I'm actually certified by the Water Quality Association as well. I've tested this carbon filter with a chlorine test strip to see the longevity of the filter for my refrigerator.

Well, my refrigerator light indicated it needed to be replaced after about 6 months but even then I tested the water and it showed up to be fine. Another 3-4 months go by and I'm still testing the water for chlorine and it still passes.  I've even checked for any kind of dumping which there was nothing.

Overall it's a good carbon block filter and lasts much longer than the stated refrigerator light indicator but then again we have a house hold of 2.
