Can this tech be used to make a (quieter) room fan?

Yes. Sharper Image sold one called the "Ionic Breeze". They generate ozone, which is a problem however. https://en.wikipedia.org/wiki/Air_ioniser

Ozone burns everything it touches. It smells nice while it destroys cells in your nose, throat, and lungs.

Ozone-producing consumer devices are banned in California. They are legal to sell in other places because of the negligence of regulators.

First thing when i saw this. Would these airplanes just be flying cancer sprayers? lol

At least ozone is less dense than air, it'd rise and eventually even bolster the ozone layer which sounds like a win.
