Product review (1 stars): REALLY disappointed we spent our money on this and gave it ...
The description for the item indicated it was a replacement for filter WSW-4. The item we received has a different neck - needed to be longer than what is on the filter we received. It is possible we received the wrong filter because I ordered this one (RFC1400A) but we received RFC 0100A. REALLY disappointed we spent our money on this and gave it a try.
