Query: Perfect Fit!!

Purchased this product for my Moms Kenmore Air Cleaner.The Filter is no longer available to purchase in the store and she had this in her basement unable to use. She had purchased other air cleaners but never got the results as she had with her Kenmore. I found this product online and it clamed to be a fit also for the Kenmore Cleaner and low and behold it is a perfect fit, operational, and my Mother is a happy camper.
