Abstract:
1. An air cleaning apparatus comprising a housing having one or more air inlets provided for air extraction and an air outlet, wherein the housing encloses a droplet removal chamber for removing droplets from airflow, a deodorization and disinfection chamber for removing air contaminants in the airflow and an air delivery unit for airflow generation, wherein the droplet removal chamber have a water exhaust outlet and encloses a ROS generator and a droplet filter, the deodorization and disinfection chamber encloses an adsorbent filter, a dust filter located in front of the adsorbent filter along the airflow direction, and a ROS generator located in front of the dust filter along the airflow direction, the treated airflow is either discharged or redirected to urinal or toilet bowl for further circulation; ROS released by the ROS generator are actively transferred by the airflow towards the adsorbent filter for decomposition of air contaminants and disinfection, and when delivered to the dust filter, ROS eradicate bacteria and virus trapped on the dust filter thus avoiding secondary pollution, wherein both the dust filter and adsorbent filter are rejuvenated for further adsorption without causing secondary pollution.
