A:AnswerHi! We would need the model number of the Refrigerator in order to confirm which filter you would need. You can reach out to assistance at Whirlpool 866-698-2538 Mon-Tues 8 AM-8 PM Wed-Fri 9 AM-7 PM EST. Be sure to have your model number so we may help you with the information needed.
A:AnswerHi Chris, the filters are NSF certified to reduce 28 contaminants including lead, pesticides and pharmaceuticals. They are not reverse osmosis. They utilize 3 types of filtration, Particle-Filtration, Micro-Filtration and Adsorption-Filtration. Here is the link to the description: https://bit.ly/3ywjmRy We hope this helps!
A:AnswerYes it does. You can confirm this it at the Whirlpool website. And Best Buy sells it for less which is even better!
