Just don't touch is a tall order with Dyson hand dryers. They are fundamentally hard to use correctly because of tight clearances.
The way they work is based on the idea of a narrow stream of air that gets water off your hands better. But for the stream to remain narrow and not dissipate, you have to get your hands close to the equipment. It's based on almost but not quite touching it.
Positioning your hands in a careful and controlled manner is, ergonomically speaking, an uphill battle. So on average, it won't happen often.
In other words, Dyson hand dryers kind of trap you into accidentally touching the part you don't want to touch.
Worse, the same applies to all the people who used the hand dryer before you. It's a very reasonable bet that the surface where the air comes out has been touched by someone who didn't use soap when they washed their hands.
I can't say I've ever experienced this issue with the air blades. They seem easy to use them without touching any part of the hand dryer. I'm surprised that people have trouble with this!
Are you some kind of superhuman? Even if you try really hard and aim precisely, as soon as the air turns on your hands get pushed to one side because the pressure is not exactly the same in both sides.
Weird... maybe they are different where you are? Older models, or not installed/adjusted correctly?
I use these all the time (they’re pretty much everywhere in the U.K.) and haven’t experienced this unbalanced pressure issue.
They always seem pretty much equal pressure on each side to me.
With large hands, there's an extra degree of difficulty to avoid touching the sides and the bottom. It still leaves you with wet wrists and damp fingers.
