The 3M HF-20S Water Filter Cartridge (part #5615109) is the genuine replacement cartridge for the 3M ICE120-S water filtration system, commonly used in commercial ice machines in restaurants, cafes, hotels, hospitals, convenience stores, and other foodservice operations.

Designed with a sanitary quick-change style, the HF-20S requires no contact with filter media during cartridge replacement — making changeouts fast, clean, and tool-free. No pre-activation is required, so the unit is ready to perform immediately after installation.

The cartridge reduces sediment, cysts, chlorine taste and odor, and scale through a proprietary scale inhibitor — protecting ice machines from mineral buildup that shortens equipment life while delivering consistently clean, great-tasting ice. At 0.5 micron filtration, it captures fine particulates that standard filters miss.

With a 9,000-gallon capacity and 1.5 GPM flow rate, the HF-20S is built for commercial-volume applications where filter life and flow consistency matter. NSF listed for performance and safety.
