Samsung Electronics has introduced a washing machine that uses the antibiotic properties of silver instead of hot water to disinfect clothing.

When the “Ag Plus” washing machine is set on “Silver Sterilization,” the system generates silver nanoparticles that kill off most of the bacteria and mold in the laundry load without using hot water. The inside of the washing machine tub is also specially treated to kill bacteria and mold and suppress the odor and contamination that accompanies bacteria and mold formation.

After the washing is complete, clothes have been found to be completely devoid of bacteria, earning the “Sterilization Mark” from the Korea Testing & Research Institute for the Chemical Industry, company officials said.
