Update on Filters fast. https://www.filtersfast.com/p-Aquafresh-WF537-Filter-Replacement-for-W10295370A.asp The replacement light came on to change the filter so I looked it up above. The site's disclosure. This product is not affiliated or sponsored by Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, Sears, or Kenmore They sell them for $30.00. The brand Whirlpool recommends is $49.00. I found it on Amazon for $45.00. It will be here Monday. I'm not sure I would buy an off brand based on their own disclosure.
