Product review (2 stars): BEWARE : may be a gamble with this filter purchase!
First time purchasing this brand refrigerator filter. Will not buy again. After following all instructions, the water had a bad taste to it. We were sure to filter out 2 1/2 gallons upon initial install. So went to other customer reviews and there were other similar issues with their purchase. We followed what another reviewer was told when they contacted customer service. Remove filter and hold filter under warm water. Wound up disposing of the first of the twin pack. Interesting how the second one was fine. So it's a gamble whether you will be lucky enough to have gotten your money's worth buying this brand. Had no issues with other off brands. Will go back to the previous manufacturer.
