METHOD AND APPARATUS FOR AIR CLEANING

摘要

An air cleaning apparatus and a method for removing air contaminants are disclosed. The air cleaning apparatus comprises a housing (1) in which at least one adsorbent filter (2) and at least one reactive oxidizing species (ROS) generator (3) are installed. The adsorbent filter (2) is positioned at the surface of the housing (1) and exposed to the air for adsorption of air contaminants. The ROS generator (3) for generation of ROS is enclosed by both the housing (1) and the adsorbent filter (2). The method comprises the following steps: a) the air cleaning apparatus is placed in the polluted environment; b) the adsorbent filter (2) adsorbs air contaminants from the environment; c) after/during the adsorption of air contaminants by the adsorbent filter (2), ROS are released from the ROS generator (3) for decomposition of air contaminants and rejuvenation of the adsorbent filter (2). The apparatus can operate without power supply and creation of disturbance like airflow and noise during adsorption process.
