They don't actually *filter* anything
Sparks...
Some of them drag air in, ionize it and filter it before blowing it out again.
You mean that unless it is a device for capturing or selecting particulates by means of a baffle that operates on the principle of slowing down an air-stream mechanically, long enough to allow sedimentation to take place, it is not a filter?
How can you prove there is no static electricity involved in such a process?
Unfortunate choice of appellation you have there.
As it happens I was thinking more along lines of an electron stream directing dust onto a Tac-Rag or even into or over an oil or grease resevoir.
