Refresh Refrigerator Water Filter R-9990 and R-9990-s (same filter)

Ensure clean and fresh water with the Refresh Premium Water Filter. This white filter is designed to fit perfectly and provide optimal performance. Two are labeled as R-9990-S and two are labeled as R-9990. They are exactly the same and their boxes show that they both work for all the exact same models. All 4 are in boxes and haven't been opened. We bought a set and then decided to get a different refrigerator. They sell on Amazon now for $29 for a pack of 2. This listing is for all 4 together. tags: water filter, refrigerator filter, Refresh R9990, Refresh R9990s, Whirlpool filter, Maytag filter, fridge water filter, NSF certified, compatible filter, replacement filter, clean water, eco friendly filter, home essentials, kitchen appliance, filter sale, Poshmark home, water purifier, healthy living, easy install filter, filter 2 pack
