The invention relates to air ionization modules with ionization tubes removably arranged in mounts and to a support comprising the mounts. The air ionization modules are characterized in particular in that as little condensation as possible occurs while enriching an air flow with ions. For this purpose, the support has two mutually spaced plates, a first plate being an assembly plate and a second plate being a circuit board comprising the mounts. Furthermore, a body made of a heat-insulating material is located between the plates such that the second plate is arranged so as to be heat-insulated relative to the first plate. The air ionization module is used to generate ions in an air flow for at least one inner room of a building. Ionized air leads to a separation of multiple odor-causing molecules, an eradication of microorganisms, a degradation of volatile gaseous hydrocarbons, and a reduction of the oxide potential of the air, for example. In this manner, a comfortable, near-natural air is produced in the room supplied with the air.
