The air with the gases first they pass through a prefilter. The prefilter absorbs the bigger particles. Then tha air with the smaller particles passes from the ionization zone. The particles are charged positive and they glue to the negative charged plates. This way we remove the majority of the particles from the air. In the final stage there is a final filter which arrests the remaining filters. After the electrostatic filter we can install an active carbon filters for deodorization of the air.

The maintenance of the system is necessary for the correct operation. The maintenance frequency is depended to the use of the filter.
