Household air cleaners have attracted attention for air pollution control by PM₂.₅ and hay fever control. However, due to the recent pandemic of the novel coronavirus（COVID-19）, the effect of air cleaners on virus removal and control is attracting worldwide attention. On the other hand, there are many performance evaluation test methods （JEM 1467（Japan）, GB/T 18801（China）, AHAM（USA）, etc.） unique to each country, so it is urgent to establish an international standard test method. Our country has developed an evaluation test method for determining the removal performance of air cleaners against airborne viruses by Japan Electrical Manufacturers' Association （JEMA） : JEM1467 Annex D “Evaluation test of air purifier removal performance against airborne viruses”, ahead of the rest of the world, and has used it to display the performance of air cleaners. However, since it is positioned as a voluntary standard in the domestic home appliance industry, it is necessary to establish an international standard for airborne virus removal performance evaluation test method. This paper describes the trends in performance evaluation test methods for household air cleaners, the activity status of IEC/TC59/SC59N, and the international standard （IEC 63086- 1 , IEC 63086- 2 - 1 , IEC 63086- 2 - 2 , IEC 63086- 2 - 3 ） on performance evaluation test methods.
