Choosing hand dryers over tissues might save precious paper, but if one experiment is to be believed, it might just cost you your health.
Earlier this month, Nichole Ward and her classmates were assigned to find out how much bacteria would grow on a petri dish after setting it down for three minutes in an unsterilized place. She chose to experiment on a Dyson hand dryer in a public bathroom – and the results she got 48 hours later, has horrified the internet.
The picture she took shows a petri dish filled with all sorts of fungi and bacteria growing inside. Ward described her gnarly findings on Facebook:
“Ok guys..ready to have your mind blown?!” she wrote. “DO NOT EVER dry your hands in those things again. This is the several strains of possible pathogenic fungi and bacteria that you’re swirling around your hands, and you think you’re walking out with clean hands. You’re welcome.”
***Alright, Alright, Alright… now i think is a perfect time to tell you a few things. As y'all know how viral this…
Although her post was meant only for family and friends, it went viral instantly, and has become a point of debate. In response, Dyson released a statement addressing the issue.
“We’re very surprised to see these results, and unclear on the methodology employed,” the company said.
“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.”
This isn’t the first time Dyson has had to defend their hand dryers. In 2016, a study claimed that hand dryers spread significantly more germs than paper towels do.
The company hit back by releasing a video of a microbiologist debunking the scientific study, which they also criticised as having financial backing by the paper towel and tissue industry.
