Product review (1 stars): Not an official Whirlpool filter
This filter does not appear to be a Whirlpool brand filter.  It came in a white box with no label whatsoever.  The description and the packing slip say "Whirlpool".  It appears to be a poor quality substitute as the paper folds are fewer and not evenly spaced as shown in the photo and as I have experienced in the past with proper Whirlpool brand filters.  There is no indication where it is made, by whom... nothing.
