Paper towel is more hygienic than other methods for hand drying.
Hand hygiene is a very important aspect for microbiological control in any segment, and its efficiency is due to correct washing. However, little is said about the importance of hand drying on hand hygiene, as there is a high probability of transmitting microorganisms from wet skin than dry skin. In Brazilian legislation there are citations for lavatory installations that should preferably use non-recycled paper towels with non- annual activation or another hygienic system and hand drying insurance. Emphasizing that in the legislation eliminates the hypothesis of using cloth towel.

According to research comparing the microbial reduction after hand drying, as well as the hygiene of the dryer surfaces , the environment and the users, of the three commonly used methods of hand drying (air jet, air dryers hot, and disposable paper towels ), it was found that air jet and hot air dryers have greater potential for contamination.
Air-jet dryers are excellent hand dryers due to high air velocities, unfortunately this means that water droplets with micro-organisms will be dispersed over longer distances and some will remain suspended in the air for several minutes (possibly hours ), taking into account that this will depend on the initial contamination and how the hands were washed.
In view of several results presented, it is concluded that the paper towel is the best solution, but this does not eliminate the existence of good practices such as waste management with paper and a good efficiency in cleaning the dispenser, walls and even
even the choice of the best dispenser, had to exist for better efficiency of the method.
