Hoshizaki H9320-51 Single-Cartridge Water Filtration System (1-Micron Scale Inhibitor)

Great ice starts with clean water — the Hoshizaki H9320-51 protects your ice machine investment by filtering out the chlorine, sediment, and scale-causing minerals that affect both ice quality and equipment longevity.

This single-configuration system uses Hoshizaki's 1-micron nominal filter cartridge, rated to a 21,000-gallon capacity before replacement is needed. NSF/ANSI Standard 42, Class 1 certified, it's built to meet the same aesthetic water quality standards trusted across foodservice, healthcare, and hospitality operations.

Compact and space-efficient at just 18.4" installed height, the H9320-51 fits easily alongside your ice machine without demanding extra counter or under-counter footprint — a practical fit for cafe-scale installs where space is already tight.

Directly compatible with our AM-50BAK and KM-81BAK ice machines — a natural add-on for any cafe setting up a new undercounter ice system, and a smart upgrade for anyone looking to extend the life and performance of an existing one.

Backed by a 1-year manufacturer warranty on the full system (excluding replaceable cartridge elements).
