Product review (1 stars): Intermittent terrible taste
I have received filters from this brand before with no issues.  I just got these last week and installed into the fridge, ran 3 gallons of water through the filter (suggestion was 2.5 gallons) and everything was great.  The flow was perfect and all was good until the following morning when I gave my son a cup of water & he said it tasted funny.  I tasted it too and he was right. So I removed the filter & reinstalled it thinking maybe I did something wrong, even though I have installed many, as my refrigerator is 7 years old.  I ran another 3 gallons through it and again, it tasted fine.  Later that day, I get a cup of water and again it tastes fine.  The next morning, I dump out the first cup, thinking maybe upon "startup" the next day, water needs to be cleared from the line.  The water tastes funny again.  I finally get a decent tasting cup of water, fill my son's bottle to bring to school for the day and he comes home saying the water tasted gross, but he drank it.  So I start researching water filters and am going with a completely different company; hopefully with better luck.  And from now on I will only buy NSF 53 certified filters, not NSF 42, as I have now done my research  & found the 42s do not remove harmful contaminants. Nonetheless, the NSF42 is supposed to remove bad tastes & odors.  This one didn't and I will not buy from this company again.
