Product review (4 stars): Very good water filter.
This Culligan ice maker water filter replaced a previous level 2 filter. I think this one makes the water taste even better. Two minor quibbles, the water line connections will not work with copper tubing as the old unit did. I had to install new fittings to switch from copper to plastic for the input and plastic back to copper for the output. Fortunately, even with the extra plumbing, nothing leaked. Also, one of the other reviewers said this filter made the ice clear. It did not do that for me. Maybe it depends on local water quality. Clear ice would have been so cool, though. Otherwise, works great.
