Comparison of Different Hand-Drying Methods: The Potential for Airborne Microbe Dispersal and Contamination
2Published by Journal of Hospital Infection
As part of this study, researchers looked at how various hand drying methods can impact the potential for cross-contamination and spread of microbes in the air. Researchers compared four different hand drying methods – paper towels, a textile roller towel, a warm air dryer and a jet air dryer – using three different test models: acid indicator using lemon juice, yeast, and bacterial transmission from hands when washed without soap.
The study confirmed that single-use towels spread the fewest microbes of all hand drying methods. This includes not just transferring microbes onto other users’ hands, but also into the air and onto surfaces around the washroom. The jet air dryer, however, spread the greatest amount of liquid and microbes and blew them the furthest distance during this experiment, demonstrating a high risk of cross-contamination.
