“All Dyson Airblade hand dryers have HEPA filters that seize particles as small as micro organism from the washroom air earlier than it leaves the machine,” the corporate mentioned. “Dyson Airblade hand dryers are confirmed hygienic by college analysis and are trusted by hospitals, meals producers and companies worldwide.”
Whether or not hand dryers do, the truth is, unfold pathogens is a matter of dispute amongst scientists.
“The recent air will kill the micro organism on the arms, however some research have discovered they can even deposit micro organism within the restroom in your arms — i.e., from the air,” mentioned Charles P. Gerba, a microbiologist on the College of Arizona.
A examine revealed in 2016 in The Journal of Utilized Microbiology discovered that jet air dryers — high-powered machines just like the one Ms. Ward used — contaminated the encircling space with 1,300 occasions as many viral particles as a paper towel would. Commonplace hand dryers — those who merely blow heat air — unfold far fewer particles, however nonetheless 60 occasions as many as a paper towel. (Dyson mentioned when that examine was launched that it had been carried out below unrealistic circumstances: Individuals’ arms had been totally coated with a virus, which might not be the case for a typical pair of just-washed arms.)
An identical examine in 2014, utilizing a bacterium as an alternative of a virus, discovered that jet air dryers unfold four.5 occasions as a lot micro organism as heat air dryers, and 27 occasions as a lot as paper towels — however the examine was funded by a commerce affiliation for paper producers. One other examine revealed in 2010 discovered that jet air dryers resulted in fewer micro organism on the arms than heat air dryers — but it surely was funded by Dyson.
One of many few independently funded research on the topic, revealed by the Mayo Clinic in 2000, discovered no statistically vital hygienic distinction between dryers and paper towels.
