Likewise, people ask, why you should never use hand dryers in public restroom?
That's not all, because of the air, the viruses can spread about 10 feet on every use of the hand dryers. The research explains that these hand dryers found in public washrooms do so by sucking in bacteria from the surroundings, such as flushing toilets and disperse them on to your hands once you use them.
One may also ask, are hand dryers actually full of bacteria? As well, the researchers found minimal amounts of bacteria on the nozzles of the hand dryers. They concluded that most of the bacterial splatter from the hand dryers had come from the washroom air. In addition, air from real-world bathrooms may contain fewer bacteria than the bathrooms in the study.

Using a hand dryer after washing your hands “is so unhygienic that it might be better to not wash at all”, according to The Daily Telegraph. The newspaper said that the moisture left after only partially drying your hands with an electric dryer makes the spread of bacteria more likely.
How do hand dryers spread germs?
“The hot air will kill the bacteria on the hands, but some studies have found they will also deposit bacteria in the restroom on your hands — i.e., from the air,” said Charles P. Standard hand dryers — those that simply blow warm air — spread far fewer particles, but still 60 times as many as a paper towel.
