it don't sent the ions a way, but around the champer only.
I said it detect the small air negative ionizer from 5 meters when I put the ionizer infront of the mineoro unit from 3 to 5 meters it beebs.
I think the mineoro unit has two main circuits, first is VLF detector and the second is ionizer. it detect the ions' collisions around the champer.
this is just a guiss.
