In general, the ice cube makers do not require a filter to produce ice. However, having an ideal filter will help you make better ice and increase the overall longevity of the appliance itself. Even though you might enjoy the unfiltered ice that your ice cube maker makes, there are quite a lot of benefits of using the ice cube makers that utilize the filters in them. For instance, the machines with filters help you improve the quality of ice by removing contaminants. Besides, it also reduces maintenance and repair needs.
