Quality according to industry standards –
Dr. Hönle AG

The Hönle Group has been a manufacturer of UV systems since 1976 and is one of the world’s most successful suppliers of industrial UV technology. Since 2020, Sterilsystems GmbH, another expert for UV disinfection, has been part of the group of companies. Hönle products are German workmanship – from engineering to craftsmanship. We rely on qualified employees and the highest quality standards to supply our customers with high-quality products. Our UV systems are used in the printing, automotive, aviation and pharmaceutical industries, among others, and enjoy international trust.


The transmission of SARS-CoV-2 viruses mainly takes place via aerosols that are released into the ambient air when breathing. UVC recirculating air disinfection systems can be used to reduce the germ load in the environment. The process of chemical-free UVC disinfection has already been used successfully for many years in the production and healthcare sectors. The new SteriWhite Air Q is a highly efficient UV system for disinfecting room air. When UV radiation with a wavelength of 254 nm hits aerosols, the viruses (including coronaviruses), mould spores and bacteria contained in them are inactivated and thus rendered harmless. During the disinfection process, people can stay in the room at any time without any risk. The inactivation rate for corona viruses achieved in the laboratory is 99.99% on surfaces. This makes the SteriWhite Air Q the optimal addition to your hygiene measures.

In addition to the floor-mounted unit, variants for ceiling or wall mounting are also available. With a throughput volume of approx. 115 up to 900 m³/h depending on the unit version (at standard room air: 20°C and 50% humidity), the SteriWhite Air Q is suitable for significantly supporting the current hygiene measures in restaurants, schools or even doctors’ surgeries by means of UVC recirculation air disinfection. Depending on the room volume, several units should be used.

Hygiene in care and nursing

Elderly people and those in need of care must be protected. That is why surface disinfection and many other measures play a major role as part of a holistic hygiene concept in the areas of care and nursing. Especially where people are cared for and direct contact is particularly important, many rooms can simply be made safer with UVC recirculating air disinfection from Hönle, without any impairment of the process and completely harmless to health. In this way, you add another important component to your hygiene concept.
Special conditions


The effectiveness of UVC disinfection against corona viruses has been clearly proven in the laboratory (tested in the S3 laboratory on surfaces). The closed system of the SteriWhite Air Q purifies between 115 and 900 m³ of room air per hour, depending on the unit, and renders harmful viruses, bacteria and mould spores harmless within seconds.

The noise level corresponds to a very quiet room fan at low speed (from 1 m away). The noise level of the SteriWhite Air Q115 is below 35 dB. The SteriWhite Air Q330 & Q600 at approx. 35 db(A) and the Q900 at approx. 40-43 db(A).

With an operating time of 16,000 hours, the UVC lamps installed are very long-lasting and only need to be replaced very rarely. When a lamp change is due, this is indicated in good time by a small LED on the housing. Sturdy steel housings make the units ideal for long-term use in rooms.


The SteriWhite Air Q is ready for use immediately after delivery. Plug the device into a nearby socket and start operation with a single touch of a button. Plug & Play – with a service life of up to 16,000 hours, the SteriWhite Air Q is a reliable companion.

If you have chosen a unit for wall or ceiling mounting, it comes with a bracket, screws and detailed mounting instructions. The length of the cable (with cold appliance plug) is 3 metres.

The SteriWhite Air Q is mounted either on the wall or ceiling according to your needs. After connection to a power source, this UVC recirculating air purifier is also immediately ready for use.

Which and how many SteriWhite Air Q units you need for your rooms depends on various factors. In our product flyer you will find the table AIR CLEANING CONCEPT. This table is based on the “COVID 19 Aerosol Transmission Risk Calculator” of the Max Planck Institute for Chemistry.
Of course, we are also available to advise you personally on the selection of the appropriate device(s).

The UVC recirculation air disinfection can rid the room air of harmful bacteria, viruses and mould spores according to the performance of the unit. However, since it is a closed system, only the air is purified. To avoid infections, please additionally observe the current hygiene regulations.

The SteriWhite Air Q as well as the other Hönle UVC recirculating air disinfection units do not contain HEPA filters. The mode of operation of the devices makes the use of filter systems unnecessary. The ambient air is sucked in and passed by two UVC lamps inside the steel housing. Regular, cost-intensive replacement of air filters is not necessary. The products of the SteriWhite Air series are particularly maintenance-friendly, reliable and quiet in their functionality.
