Product review (3 stars): This is NOT a RPWFE!
I am sure that it all someone needs if they need a RPWF filter, but it is NOT a RPWFE filter and will not work as one.  The seller did what they were supposed to do, but the description and title of the product is misleading.  I was able to return for a full refund, but would have preferred not the hassle.  I hope this will help someone else looking for a RPWFE.
