Kind of a selective reading of this paper.
Taylor et al47 evaluated whether hot air dryers change the levels of airborne microorganisms in the washroom environment. They found that air emitted from the dryer outlet contained fewer microorganisms than air entering the dryers. They also found that levels of microorganisms on the external surfaces of hot air dryers were not different from those on other washroom surfaces. Thus, the authors argued that hot air dryers were appropriate for use in both the health care and food industry. Similarly, Matthews and Newsom48 compared the bacteria aerosols released into the air when drying hands by using 4 different models of hot air dryers and by using paper towels. They found no difference between aerosols liberated by paper towels and 2 models of hot air dryers, whereas the other 2 models of hot air dryers generated fewer aerosols than paper towels. They concluded that hot air dryers were safe from a bacteriologic viewpoint.

Mythbusters also did an episode on it and found the same results.
