The 3M™ HF90-S-SR carbonless replacement filter is used by the ICE160-S-SR commercial ice machine filtration system. The cartridge is specifically designed to help prevent biofilm buildup inside commercial ice machines.

The HF90-S-SR maintains source water chlorine levels to inhibit potentially harmful ice machine biofilm buildup commonly found in high humidity foodservice locations such as breweries or bakeries. 

Therefore, the environment surrounding a commercial ice machine can impact the performance and service requirements due to biofilm buildup. Excess moisture can increase the risk of potential growth and spread of biofilm-associated bacteria, making ice machines a common target for restaurant inspections.

This carbonless filter features a 0.2-micron filtration design that maintains chlorine and chloramine levels, while reducing sediment, particulate, bacteria, and cysts. 

In addition, the HF90-S-SR has a built-in scale inhibition can help to prevent the potentially harmful effects of scale build-up on equipment.
