Product review (4 stars): which in doing so smelled like rotten milk
After reading the reviews of others, I decided to go ahead to purchase this product even though one of the reviewers suggested that since the filter in their refrigerator showed no signs of being clogged he was not going to replace it. I believe this filter is a "Odor" filter, since it's has a  Charcoal insert, and not a DUSTt filter. After removing my filter I took a "Whiff" of the filter, which in doing so smelled like rotten milk. I submit that one should do the same before not replacing it.
