I took two straight pins and soldered them to the end of a wire. A small round stainless steel wire brush soldered to the wire end would be an alternative option. I put this wire in some Teflon tubing, but one could use rubber or any good insulator. I used a rubber grommet where it goes through the aluminum air duct tube.
With the positive lead grounded this generates negative Ions being sprayed out of the tip of the needles. You can
see the tiny sparks in the dark. If these ions are sprayed into a room without a positive grounded plate or without
going through an air filter element, the walls tend to eventually turn black from soot (observed from experience).
If one puts this in the pipe that is used to suck air in from the outside and passes this ionized air through an air
filter element the soot tends to end up in the air filter. I didn't do this, didn't think it was necessary at the time, but
one could use a copper wire screen mesh on top of the first filter element. The mesh would be grounded or
positive to help attract the charged particles.
Air ions help filter out charged particles. They do not help filter out chemicals. Ozone sometimes breaks down
chemicals to render them harmless. My current understanding is that both negative Ions and Ozone (of the right
type) in the proper amounts are beneficial to animals and mankind. I use a separate Ion-Ozone generator once the
air gets through the particle-charcoal filter into the room. Good Ozone generators tend to be expensive. They will
be useful in killing off and preventing mold after the pole shift.
