Speaking from experience here, and limited information from the company, this looks like a polished version of a high-voltage grid accelerator.

What can be an expected concern is that besides ionizing air and imparting motion to neutral air molecules as the ionized ones rush from one plate to the other, that same effect can and will charge dust particles. That “collector plate” will need to be easily accessible.

Sound familiar?
