A novel air disinfection and purification system called CKER (Coronavirus Killer) was developed at the crucial moment of global epidemic prevention and control. The CKER system was based on three Gree patented core technologies, namely the high efficiency trap technology based on the combination of high density plasma and HEPA, the accurate temperature control technology based on target temperature of virus inactivation and the rapid purification method of space airflow organization.

The CKER system has already been applied in our novel antivirus air purifier, which was developed epically to kill the SARS-CoV-2 coronavirus. The test results of the third-party authority showed that the antivirus air purifier using CKER system can rapidly reduce the fine particulate matter and eliminate a range of harmful pathogens. Moreover, the field test report from Wuhan Institute of Virology, Chinese Academy of Sciences clearly proved that the inactivation rate of SARS-CoV-2 is higher than 99% after one hour operation.

Up to now, the products have been exported to more than 50 countries and regions around the world, the sales of the products have reached more than USD 156.7 million, adding USD 24.1 million in profits and USD 11 million in taxes.
