Device uses movement of ions to generate airflow without any moving parts like in iPads and MacBook Air.

Ionic acceleration of air needs high voltages and the air gets ionized (the reason people recommend against vacuuming a PC). I'm surprised that it works at all in close proximity to sensible tech.

Edit: right, low static pressure, meaning: lower voltages. But still not low.

the reason people recommend against vacuuming a PC

A regular vacuum isn't doing anything with ions or high voltages. Moving air can generate potentially harmful static electricity, but usually the reason people recommend against vacuuming a PC is because if you spin the fans doing that, the motors inside turn into generators and drive current back into your PC parts that could damage them.

Moving air can generate potentially harmful static

Well, and what do you think creates that static electricity? Ionization.

Feeding back electricity, that's why motors usually have a diode or something.

They use a grounded faraday cage around it. Video on it where he touched on that https://youtu.be/fyai_kUYhLs

Can't watch the video rn, anything about the dust problem?

He just mentions they have a solution but it’s patented so they wouldn’t talk about it. Take that as you will of course

Strange, patented means it should be findable on the USPTO system, diagrams and all. And yet..
