Hand dryers spread germs: University of Leeds Research

Hand dryers generally used in public toilets have a major role in spreading germs, as per a new study conducted by research team at the University of Leeds. Earlier studies have also suggested that air dryers spread germs further compared to paper towels or napkins. Air dryers spread germs into the air and even people who don’t air dryers can get infected due to germs spread by strong stream of air.

The research team noticed 27 times more germs in the air around air dryers compared to air around paper napkin dispensers.

Mark Wilcox, professor at the University of Leeds informed, "Next time you dry your hands in a public toilet using an electric hand dryer, you may be spreading bacteria without knowing it. You may also be splattered with 'bugs' from other people's hands."

The findings of the study team have been published in the Journal of Hospital Infection.

A woman from California shared an image on her Facebook account about the same issue. The post became viral and many social media users have shared the image. The woman claims that she left a Petri dish in a
Dyson Airblade hand dryer for three minutes. She then incubated the dish for two days and discovered an alarming amount of bacteria grew in the dish.

Dyson has strong market share in air dryer segment. The company issued a statement about safety of its air dryers, "We're very surprised to see these results, and unclear on the methodology employed. All Dyson Airblade hand dryers have HEPA filters that capture particles as small as bacteria from the washroom air before it leaves the machine. Dyson Airblade hand dryers are proven hygienic by university research and are trusted by hospitals, food manufacturers and businesses worldwide."
