I’am looking for something to help find more about the Ion Generators, how they work what is in side and so on. thank you!

Ions are just atoms or molecules that have a charge - that is, they have more or less electrons than protons. To create an ion, you take an atom that has the same number of electrons as protons and remove or add one or more electrons. There are quite a few ways that this can happen - commercial ion generators are just one.

One of the most common kinds of ion generator is a machine that simply generates a high voltage an places this on a surface with one or more tiny sharp points sticking out of it. The electric fields at the tips of these sharp points will be very large, and this will in turn cause ions to be expelled from the region around the tip.

Some of these ions will stick onto small particles in the air - such as small bits of dust. In fact, this is how electrostatic air clearers work - in these devices the charged dust particles are attracted to a nearby grounded metal plate or rod.

Some great information is available at
