One of the most efficient ways to prevent the spread of germs is to avoid touching surfaces. The simplehuman touch-free sensor pump is an easy and automatic way to ensure no germs are spread to the next user – making your environment more hygienic and healthy. While dispensing, the flexible silicone valve springs open for a quick, steady flow. As soon as the dispensing stops, the valve snaps shut to create a seal — preventing messy drips. Although you can use any liquid soap, hand sanitiser or lotion (expect those with exfoliants or micro beads) simplehuman soap is the optimum consistency for this sensor pump. Just one contains almost as much soap as five commonly used soap pumps, so they’re easier on the environment.
