You're worried about the germs? I'm worried if there is water in the sink and the fan kicks in at 400mph, what happens to that displaced water?

The AirBlade when it's not properly calibrated makes a big enough mess as it is...

I agree. I would imagine that in with many basin designs the filtered air would hit the basin, collect bacteria and deflect towards your face.

I remember reading somewhere (can't remember the actual article) about how many doctors will not use air dryers in public bathrooms. Ever since then I have always dried my hands on the inside of my shirt when disposable paper towels aren't available.

It might be slightly preferable to the existing problem with the AirBlade where the bottom portion traps water and becomes a germ pool party.

The HEPA filter would prevent germs from being sucked in and blown onto your hands. I guess there might be issues with germs in the sink becoming aerosolized, but if the sink basin was designed properly it could become a sort of funnel so that the "dirty" air could be sucked away, separated from waste water and maybe filtered before being released back into the bathroom.

Collateral splashage seems like it will be an issue. The Today Show segment with Dyson demoing it actually shows water flying towards the camera. Matt Lauer even leapt out of the way when the blower came on.
