Product review (1 stars): do not try to force fit as you may end like me with an unnecessary repair bill
I learned after trying to force fit it , and a call to the repairman, that it is not compatible.  After it didn't work, I compared the insertion end fitting with the Whirlpool OEM, and found that they were different.  So, my advice if you buy a generic substitute is to first  look at the insertion end of the filter, and be sure that the fitting is exactly the same configuration and dimensions.  If not, do not try to force fit as you may end like me with an unnecessary repair bill.
