Bioaerosols play a crucial role in the Earth system. In particular, in interactions between the atmosphere, biosphere, climate and public health. Primary biological aerosol particles are unavoidable for the reproduction and spread of organisms in various ecosystems and can cause diseases in humans, animals and plants.

Challenges of bioaerosol monitoring

The current measuring instruments for bioaerosols available in Europe are either manual measuring methods with high laboratory effort or automated measurements with low informative value about the type, origin and properties of primary biological aerosol particles. For an operational monitoring of e.g. pollen, spores or bacteria, manual measuring methods provide a low temporal resolution and automatic measuring instruments provide too little information about the measured particle. This results in incomplete and time-delayed information about the bioaerosols in our environment.

Automated real-time measurement

Automated real-time measurement of bioaerosols 

The new generation of automated real-time measuring instruments now provide data every hour or even every minute without complex secondary processes. However, they also bring new requirements in the operation that need to be taken into account.


he solution for operational use is therefore not a single measurement system that can measure bioaerosol particles, but a combination of components for reliable real-time monitoring of bioaerosols.

SwisensEcosystem Bioaerosol Monitoring

Swisens has recognised that a single measurement system only contributes to a limited extent to progress in bioaerosol monitoring. Therefore, we offer a unique ecosystem of hardware, software and service components. We offer tools, services and support in dealing with the latest technologies and pave the way for the new era of real-time monitoring of bioaerosols.

Federal Office of Meteorology and Climatology MeteoSwiss

“Swisens has shown to be a service-oriented partner in any case, addressing requests diligently. Our suggestions have always been heard and have been systematically translated in technical improvements. In short, Swisens AG has shown to be strongly oriented towards client and market needs. Finally, the tests we performed with Swisens AG resulted in a fruitful scientific exchange. In all, it is for us a great pleasure to recommend Swisens AG for operational or research projects in the field of automatic pollen measurements.”

“I speak on behalf of my colleagues who are Urban Observatory Principal Investigators and Research Collaborators from the University of Manchester that we have rarely seen, or been provided with such exemplary support as that provided by Swisens. Swisens customer support has been remarkable given the current situation, from remote training and commissioning to rapid support for hardware and software tools specific to our needs to extremely well organised seminars that actually focus on customer feedback and needs. In particular we have been impressed with the Swisens open source data approach and their attention to different users specific needs. Swisens technical innovations has already generated enormous interest in a bioaerosol-aerobiology community that until recently has been limited with respect to real-world and near real-time detection and importantly quantification of airborne bioaerosol concentrations. Their approach has developed significant rapport with multi-disciplinary researchers and Swisens should be lauded for this.”

Finnish Meteorological Institute

“The Finnish Meteorological Institute is very satisfied with the cooperation of Swisens AG. The agreed research and development programme is progressing well and mutual openness and collaborative atmosphere strongly supports it. Swisens participated in a workshop and supported the scientists in recording the test data based on the cooperation agreement. A particular outcome of the workshop was a new procedure for the calibration of real-time monitoring systems based on the SwisensAtomizer. It has been proven to deliver cleaner results than the approaches tried so far in different countries. FMI is very satisfied with cooperation of Swisens AG. Our suggestions regarding software tools were quickly accepted and implemented by Swisens engineers. We are indeed happy to work with Swisens and start opening real-time data to professionals in Finland.”



Debora Käser
Team Leader
Department for Work Safety / Health Protection

“Being able to aerosolize different powder samples in the lab to perform experiments related to occupational health has been one of our challenges. With the SwisensAtomizer at hand, we now have a small device which helps us to produce a stable dust atmosphere to load filters in a consistent manner, serving as calibration filters for later analysis. Swisens AG has always shown great support concerning our demands on the SwisensAtomizer. We are delighted to collaborate with Swisens AG.”
