Washing your hands with Smixin uses 90% less water and 60% less soap compared to a normal hand washing cycle. The Product Combi is a unique 3-in-1 hand washing system designed to be used inside or outside the washroom. Water, soap, and paper are dispensed optimally and the system is connected to an external monitoring platform. Hygiene levels after washing your hands with Smixin (12-15 seconds) are comparable with washing your hands for a full recommended WHO guideline with a normal faucet and soap dispenser (30-60 seconds) – as confirmed by a leading testing institute.

  • Saves more than 90% water and soap compared to a traditional hand wash cycle
  • Increase handwashing behavior for students, guests, employees and others by 40% by placing a Combi handwashing station outside the washroom
  • 75% of users rate the Combi as way better than traditional hand washing
  • Only 0.12 liter of water needed per handwashing cycle - 90% water savings
  • Only 0.3 ml of soap needed per handwashing cycle
