The Hoshizaki HC and HC-H filters have been discontinued, and have been replaced with the 4HC-H Filter. The 4HC-H filter is not recommended for use with flakers. The 4HC-H Filter has a much longer filter life and is approximately 9" shorter than the previous HC-H filter, so space should not be an issue.
