Besides, dryers “ Jet “ pollute air of the toilet room, owing to the high speed of a warm air stream. Tests showed that bacteria extend in a radius of 2 - x meters from the working dryer “ Jet “. Traditional dryers extend bacteria to further 0,25 meters.
“ Paper towels showed the best result in comparison with hand-driers, considerably having reduced quantity of bacteria, both on finger-tips, and on palms “ Kate Redvey, the senior research associate of Westminster university says.
