PROBLEM TO BE SOLVED: To provide an air cleaning system capable of efficiently disinfecting indoor air by using disinfected water kept in a more stable state than ozone water and facilitating post-treatment.SOLUTION: The air cleaning system includes a plurality of air cleaners (10) which each include: an electric bacteria-collecting section (20) performing a bacteria collecting operation for capturing bacteria in the air and a feeding unit (60) performing a disinfection operation for feeding a hydrogen peroxide solution to the bacteria captured by the electric bacteria-collecting section (20). A control device (35) performs control so that the bacteria collecting operation can be performed by the other air cleaner (10) when the disinfection operation is performed by the one air cleaner (10).COPYRIGHT: (C)2012,JPO&INPIT【課題】オゾン水よりも状態が安定しており且つ後処理が容易な除菌水を用いて、室内の空気を効率良く除菌できる空気清浄システムを提供する。【解決手段】空気中の菌を捕捉する集菌動作を行う電気集菌部(20)と、電気集菌部(20)で捕捉した菌に過酸化水素水を供給する除菌動作を行う供給ユニット(60)とを備えた空気清浄装置(10)が複数設けられる。制御装置(35)は、一方の空気清浄装置(10)で除菌動作を行う際に、他方の空気清浄装置(10)で集菌動作を行うように制御する。【選択図】図1
