Review on 🚰 Moen 9601 ChoiceFlo Compatible Replacement by Lorri Ciccio

No water shut off etc. 1) Just 1/4 turn and a quick down arrow and voila! The old filter is removed. 2) Replace the battery. 3) Insert the new filter and rotate it 1/4 turn. 4) Turn on the water for a few minutes. Did. Light. I'm not sure why others are having trouble. Edit: I have purchased several of these Moen filters and have been happy with each one. I don't trust generic alternatives. More effort, but worth it.
