these are the pins... basically a negative ion generator is like a very high voltag, low amp power supply... static electricity or negative ions fly from the pins and attach to particles in the air and drag them down... or it appears as you'll see later that my vents make a static electricity field which all the dust sticks to instead of flying through the air... cigarette smoke is actually drawn into the vents (where the ion pins are) quite quickly just to show that it is working...
