Product review (1 stars): I would not buy this filter
My filter became very restricted and useless after about 10 gallons of  bottled water which runs through my refrigerator, It never seemed right from the get-go.  I suspect the filter media swelled. I have purchased this filter in the past with no issues but I also suspect they might have outsourced to China, There is absolutely no country of origin on the filter or the box. God knows you don't want anything that touches your food or water coming from China where they are even  known to adulterate baby food with industrial chemicals .  Best part !!!  the filter is clearly labeled that it has a 6 month warranty. The company rep insists it is only 30 days and refuses acknowledge otherwise. I would rather hit myself in the head with a hammer than talk to those people again.
