Product review (5 stars): Beware of the filter cover in the fridge!
The filters keep the fridge smelling nice and fresh. The problem I had was removing the filter cover to install the new filter. It says turn counterclockwise to remove the cover. It was set on so tightly I thought I was going to break the cover. With all my strength, after removing the top two shelves,  it finally turned counterclockwise and clicked open. Filter fit perfectly and the cover went back in place easily.
