Interesting article about hot air dryers in public toilets
An interesting article regarding hot air dryers in washroom suggest that when drying your hands with hot air causes you to walk around with a lot more bacteria than when drying your hands with paper towel or those cotton looping machines.
I understand the message if you’re really concerned about bacteria on your hands. But to be honest, the amount of bacteria left on your hands isn’t life threatening. How many resources of the earth is being used to make paper towels? It takes up energy, earths resources and then waste after it’s been used.
I think hot air dryers is the better solution as it only takes up energy. Like they say in the article, air filters can be installed to purify the air before it goes intro the air dryer.
