SARS-CoV-2 viruses are mainly transmitted via aerosols released into the air when you breathe. UVC air disinfection can be used to reduce the germ load in the immediate environment. The chemical-free UVC disinfection process is already used to a high degree of success in the production and healthcare sectors. The new SteriWhite Air Q is a highly efficient UV system for sterilizing room air. By irradiating the aerosols with UVC at 254 nm-wavelength, viruses (including coronaviruses), mould and bacteria in the air are inactivated and rendered harmless. What’s more, SteriWhite Air Q is a closed system which means there’s no need to vacate the room while disinfection is taking place.
A disinfection rate of 99.99% for SARS-CoV-2 was achieved on surfaces in the lab. Disinfection devices from Hönle were also proven to be effective against corona, making them suitable supplements to your other hygiene measures (in line with the current applicable regulations).

The effectiveness of UVC disinfection against coronaviruses has been proven in the lab (tested in a S3-lab on surfaces). The closed system SteriWhite Air Q purifies, depending on the device version, 115 m³ up to 900 m³ of room air per hour and renders harmful viruses, bacteria and moulds inactive within seconds.

The noise level corresponds to a very quiet room fan at low speed, from a 1 m distance. The noise emission of SteriWhite Air Q115 is less than 39 db(A). SteriWhite Air Q330 & Q600 emit approx. 40 db(A), SteriWhite Air Q900 approx. 47 db(A).

With a service life of 16,000 hours, the built-in UVC lamps are extremely long lasting. A service-display on the housing gives an early warning for the rare lamp exchange. SteriWhite Air Q comes with a sturdy steel housing as Hönle disinfection devices are designed for long-term use.

Which and how many SteriWhite Air Q units you need to disinfect your room air depends on various factors. In our product flyer we have compiled an “Air purification concept” table for you, based on the “COVID-19 Aerosol Transmission Risk Calculator” of the Max Planck Institute for Chemistry.
If you need help in selecting a suitable device, we will be happy to assist you personally at any time.

Depending on the power of the disinfection device, UVC air disinfection can reliably inactivate harmful bacteria, viruses in the room air. As SteriWhite Air Q is a closed system, however, only the air is disinfected. To avoid infection, you should still follow the latest hygiene measures.

SteriWhite Air Q and other UVC air disinfection devices by Hönle do not contain any HEPA filters, as their operation mode makes it unnecessary to use any filter system at all: The ambient air is sucked in and passed over two UVC lamps inside the steel housing, where the germs are inactivated. Consequently, there is no need for the regular, costly exchange of filters. Products from the SteriWhite Air series are particularly low maintenance, reliable and silent.


UVC air disinfection should be used to supplement other measures as part of efforts to stop the spread of Covid-19. To avoid infection with SARS-CoV-2, surfaces must still be disinfected and rules relating to social distancing and wearing a face mask covering both the nose and mouth must be followed. Always follow the latest Covid-19 guidelines.
