What happens when flushing? Toilet aerosols explained
When flushing, more happens than you might expect at first glance: during the flushing process, tiny water droplets are created under high pressure, so-called aerosols. These contain everything that was previously in the toilet: bacteria, viruses, and other microorganisms. According to recent studies, these microdroplets can be propelled up to 1.5 meters into the air – spreading throughout the room, often several meters away. This means that not only adjacent surfaces, but also more distant areas such as handrails, door handles, or even washbasins can become contaminated with germs. Sounds like a good reason to close the toilet lid before flushing, doesn’t it?
Especially in high-traffic sanitary facilities such as offices, schools, care institutions, or restaurants, open flushing is an underestimated factor in the spread of infectious diseases.
