Air purifiers used against corona/covid-19 and other viruses
Research has shown that long-term exposure to pollutants such as fine particles of nitrogen dioxide (NO2) and sulphur dioxide (SO2) can reduce pulmonary (lung) function and cause respiratory disease. Such contaminants have also been shown to cause persistent inflammation even in relatively young people and thus increase the risk of infection with viruses such as COVID-19/SARS-CoV-2, which target the airways. Air purifiers used against coronavirus and other types of airborne viruses reduce exposure to such.
Several studies have already reached the conclusion that poor air quality can increase the risk of being infected with COVID-19 and also the risk of becoming seriously ill or dying. A study in the USA shows that even a small increase in PM2.5 concentrations of 1 microgram per cubic metre produces an eight percent increase in the death rate. According to another study conducted in the Netherlands, the corresponding figure there is up to 16.6 percent.

Air purifiers with HEPA reduce the spread of viruses
High-quality air purifiers with HEPA filters are an important tool for minimising the spread of coronavirus, which is transmitted via large droplets or extremely small ones with an ability to float around in indoor air for hours. It was stated in the scientific publication “It is Time to Address Airborne Transmission of COVID-19” signed by Professor Lidia Morawska, WHO Collaborating Centre for Air Quality and Health, together with 239 other international researchers in July 2020.
