Ok so after much avail (many hours of research) I've only found one site that has this vital component, the "12VDC Negative Ion Generator". If anyone knows a better way to get it, please post back!!
the url,
Negative Ion Air Purification Systems
It's $30.00 but even so, this and a few other parts will not cost $178.00 like the "electric touch". I'm going to make this soon and I'll post back.
You'll see it when you scroll down a bit to the "For Negative Ions Operating at 12VDC" section of the page.
