Drying efficiency:
Cloth towels had a higher drying efficiency than warm air dryers. Paper towels and jet air dryers have a similar efficiency, which is higher than the warm air dryer.

Electric dryers favored:
Seven studies favored electric dryers over paper towels, but underlying reasons were mixed. Some had observations of less bacterial counts in the environment or on external device surfaces, or less concentration of liquid droplets on surfaces near towel or dryer devices.

Paper towels favored:
Thirteen studies favored paper towels over electric dryers, with seven showing statistically significant differences.

Paper towels and electric dryers equal:
Eight papers favored both methods equally, as they, for example, found no statistical differences in microbial aerosols.

Review does not give all details on included studies; these are therefore extracted from original studies.
