IQAir’s HyperHEPA technology has been tested and proven to filter biological contaminants, bacteria, and viruses in their airborne state. This includes aspergillosis, MRSA, and SARS-CoV-2, the virus that causes COVID-19, which is the major reason that HyperHEPA filtration was used by the Hong Kong Hospital Authority to help protect staff and patients during the SARS-CoV-1 epidemic and the SARS-CoV-2 pandemic.
