Intended Use:

The 3M HWS100 is a Water Softening System designed to reduce spotting on dishes, glasses and flatware, while reducing scale build-up throughout the dishwasher components. This softening system uses a high-temperature resistant resin that has the ability to remove calcium and magnesium minerals for high capacity dishwashers.


The HWS100 will eliminate the hard scale and mineral build-up, while increasing the performance and the longevity of your dishwashing machine. The 3M HWS100 Water Softening System softens the water more efficiently which reduces excess chemical usage.
