Hand sanitizer dispensers are devices designed to dispense hand sanitizer, a liquid or gel used to reduce germs on the hands. They are commonly found in public places like hospitals, schools, and offices to promote hygiene and prevent the spread of illness. These dispensers can be manual or automatic, with automatic models using sensors to release the sanitizer without physical contact. Most hand sanitizer dispensers are filled with alcohol-based solutions, which are effective in killing many types of germs. They come in various styles, including wall-mounted and free-standing units, making them versatile for different environments. Regular use of hand sanitizer is recommended, especially when soap and water are not available.
