Review on 🧊 Whirlpool Refrigerator Air Filter Replacement Pack - Model W10311524, 4-Pack - Improve Air Quality and Extend Appliance Lifespan! by Toki Louton

Doesn't exactly match the case but that's a plus for me. The flap covering the filter prevents it from falling out. The proprietary filter was so dense that removing the filter was often a colossal task. To be honest I don't expect the filter to last a full 6 months like a well known brand. 4 months was the best I've seen and with the price difference if I only get 3 months I'm still a few bucks ahead on the filter.
