Product review (5 stars): Same filter, better price.  Quit the Whirlpool filter club!
This filter is the same part number, design and quality as the filter you would purchase from the "Whirlpool Filter Club". The very best part is the price!  Anyone who has joined the filter club in the past knows that after the "introduction price", your next order would no longer reflect a discount. I am greatful to have an oppurtunity to purchase at a fair price. :-)
