No one washes their hands perfectly (e.g., ready for surgery), so when you dry them there’s still a lot of bacteria present. Dyson dryers aerosolize those particulates, and they do it far more than other dryers.
Think of it this way — they don’t dry your hands, they blow the water off. Where does the water go? All over the bathroom. Dyson dryers disperse fluids up to 3 meters away.
