Foam soap dispensers are devices designed to dispense liquid soap in a foamy form. They work by mixing air with liquid soap, creating a lather that is easy to apply and rinse off. These dispensers are commonly found in public restrooms, kitchens, and homes, promoting better hygiene by encouraging handwashing. The use of foam soap can be more economical than traditional liquid soap, as it requires less product per use. Additionally, foam soap dispensers often have a touchless option, which helps reduce the spread of germs by minimizing contact with surfaces.
