I just used one (not the first time) and noticed that there is no where for the water to go. With a paper towel the the bacterial laden film of water on your hands gets trapped in the cellulose fibers (and left on the handle of the dispenser for the next guy). With a regular hand dryer the water is evaporated off and convected away, leaving the bacteria on your hands (but unhappy at having been dried). but with the airblade all of those little droplets are ripped away and aerosolized where they can end up in our eyes, noses, mouths and lungs. Yum.
