Product review (1 stars): The filter info says it is compatible with the WSS-1 ...
The filter info says it is compatible with the WSS-1. It is not. The insert in the package also claims it will replace it.  The fittings are different and it won't work in my refrigerator. Unfortunately, I didn't need to replace the filter until after the date to return had passed. So, I spent money on something I can't use.
