Hi
In many places the commercial hand dryers seem to be doing okay in saving paper towel use.
For example, in Australia a lot of airports have them.
But, they lose a good deal of benefit because they can not be directed to one’s face.
Especially in the airports or other transport hubs, where a traveler may freshen up a bit with a face wash, the hand dryer that only dries hands is rather limited.
Why can you not please tweak the design so it can direct the airflow also at the face?
It can not be that difficult.
