The interview appeared in the following newspapers:



17.11.2020 - Interview with the campus radio: Correct ventilation is more efficient than filtering

In addition to ventilation, wearing a mask and keeping your distance, can you do something against the spread of the virus by filtering the room air? We tested highly efficient filter systems in a community school.

LUBW immission measuring station Reinhold-Frank-Straße

12.11.2020 – Start of the field tests: Simultaneous measurement of NO2 and fine dust immission at a measuring station close to traffic & in a new development area
In order to determine the differences in NO2 and fine dust immission between a traffic-related and a traffic-calmed environment, we measure at several locations with identical measuring technology. The measuring stations are located on the Reinhold-Frank-Straße, Karlsruhe (traffic-related area) and in Stutensee-Büchig (traffic-calmed area). The field tests have started. We thank the LUBW for their support!

Filtering Face Pieces (FFP)

24.09.2020 - Presentation at the Palas AFiS-seminar 2020: "Testing against the virus - Protection for your health"

In the context of the above mentioned seminar Prof. Dittler gave a lecture on "Filtering Face Piece - Design & Effectiveness". Masks protect, if you use them correctly.

Test eines neuartigen Innenraumfilters
Testing of a filter for interior spaces in a real environment (primary school classroom)

04.09.2020 - Investigation of the effectiveness of a new type of filter for interior spaces

In cooperation with MANN + HUMMEL, we are testing the effectiveness of a new type of filter for interior spaces for reducing particle concentration in enclosed spaces. We thank the Comprehensive School Eggenstein-Leopoldshafen for the permission to test in the real environment of a primary school classroom.


11.08.2020 - Interview with the campus radio: How masks and ventilation protect against infectious aerosols

Masks protect against infection with the new corona virus. Plastic visors, on the other hand, have little or no protective effect. The minimum distance of one meter fifty may not be sufficient in closed rooms. Frequent ventilation reduces the risk of infection. These are the most important results of a study carried out at the Karlsruhe Institute of Technology on the spread of droplets that are excreted into the ambient air when breathing, speaking or singing. More than touching surfaces, these tiny droplets floating in the air are responsible for the transmission of the corona virus.

Visit to ESTA Apparatebau GmbH

21.02.2020 – Visiting the ESTA Apparatebau GmbH

Innovative Product Development (IPD) is meeting the core of our research, which is focused on understanding fundamentals of gas-particle-separation processes. In this context we are working with innovative industry partners (e.g. through ZIM-Projects). It was our pleasure visiting ESTA Apparatebau GmbH & Co.KG today along a project related meeting. Thanks for hosting us! We look forward to continuing our fruitful collaboration.
