Product review (3 stars): Working correctly now
I purchased filter in June of 2013.  Received it around the 17th of June.  Put in refrig. July 2nd 2013 & it is now Aug. 4th and change filter light is coming on again.  It is suppose to last 6 months minimum. I think it's a used filter.  Big rip-off. I was annoyed that filter light was on already, so I wrote review. Someone put filter in for me, said he just did his Moms'. I should have read orginal directions. I redid filter insert and it's working fine, I apologize.
