Negative Ion Generators

I've been reading up on negative ion generators, and I was going to get one (they're only 12.95), but I was skeptical on safety. 15kv (!) going through my body does NOT sound safe. Yeah, it's probably low current, but alot. How is it on pain? Could it...kill me? I don't know about you, but I only have one life, and its goin good right now, so I don't really want to get rid of it.

Does anyone have experience ith these? Yes, I know about the one instructable about rigging it with your doorbell,, but even they mentioned -and I quote- "...a pretty nasty shock...", so what exactly am I dealing with? specific...
Oh, and I was thinking of the 12vdc one.

Also, will it jump (the spark), to ANY grounded metal thing?

Have you ever touched a door-nob after charging your shoes on a carpet? Static electricity is above 20kv. You'd need a fair amount of current to do injury. A heck of a lot more than a 12vdc supply would give.

A 12 volt DC supply can easily kill you if you charge the right capacitor with it.
You don't need very much current at all to stop the heart. Certainly mA not amp range.

So it should be safe?

As long as it is low current, you should be fine. I could be wrong, but one inch static electricity sparks are around 15k volts or so, but very low current.

Ok, thanks.
I did some research, and it looks like the voltage increases dramatically, and, as a law of physics, you can't make energy. Therefore, the wattage will stay the same, so the current also reduces dramatically. High voltage won't hurt you, it is high current that will, so you are very safe. How they work is confusing because capacitors are usually used to raise current, but you are right-who cares as long as it works!!!

Well, I got one. It doesn't hurt, only like a carpet static shock.
That makes sense.
Somehow my last reply didn't show up. Does anybody know how I would add a small particle collection plate to one of these? Do they need to be elactrically charged or could it be just a small removable sheet of metal? And if it does need to be electrically charged, how would I go about doing that?
why? there are 2 real types of toroids. plates and needles. plates store the most charge. needles encourage breakout. on devices like ion generators, needles are best.
