AIR CLEANING APPARATUS

摘要

The invention relates to an air cleaning apparatus, comprising a gas filtration section and a particle filtration section. The gas filtration section comprises a gas absorbing or adsorbing unit for trapping gaseous contaminants and a generator for generating reactive oxidizing species (ROS), suitable for oxidizing said gaseous contaminants. The particle filtration section comprises a precipitation unit, arranged to attract charged particles from passing air, and the (ROS) generator is arranged to charge said particles prior to their precipitation. Thus, the (ROS) generator fulfils a double function.
