Do HEPA filters catch viruses

Best air purifier with HEPA filter system against viruses

Professional air purifiers for interiors filter dust, pollen, mold spores, tobacco smoke, soot particles, but also microorganisms such as bacteria and viruses from the air. In the devices are highly efficient HEPA * filters (High-Efficiency Particulate Air Filter) installed. They also intercept the finest aerosols to which viruses such as SARS-CoV-2 adhere.

  • HEPA * filter of class H13 excrete 99.95% of viruses and other germs from the air.
  • HEPA * filter of class H14 filter even up to 99.995% of the unwanted air particles.


Which air purifier is the best?

Current air purifier studies, for example by the University of the Federal Armed Forces in Munich, have confirmed the effectiveness of high-tech air purifiers against corona viruses. In indoor air filter tests with HEPA filters, the viral load was significantly reduced. In this way, the risk of infection by aerosols could be reduced.

The best air purifiers around for schools, Universities and Restaurants meet the following criteria according to these studies:

  • You are using highly effective HEPA * filters of class H13 and H14. Only these can separate the finest aerosols that arise when breathing, speaking, singing, coughing and sneezing and which often float in the room for hours.
  • The Air flow rate or Flow rate one device corresponds to about six times the volume of the room per hour.
    Example: With a room volume of 100 m³, an air purifier must be around 600 m3 Filter air per hour.
  • The devices are particularly quietso that they do not interfere with concentration in class or in the library.
