Abfliegende Graspollen Pollenmonitoring Bluete


Swisens develops new technologies for monitoring particles in the air. In doing so, we enable new and improved solutions for industry and science with the detection of bioaerosols, pollutants and other solid particles. Working in partnership, we help our customers to improve their productivity, increase process safety and gain new insights to add financial or scientific value.


The earth and our living space are in a state of flux. So is the microcosm of the particles in the air that surrounds us. We want to make these changes visible. Our goal is to contribute to a better knowledge and understanding of the air we breathe, the food we eat and the aerosol microcosm with all its facets. Together with our customers, we work to improve the health and quality of life of people, plants and animals

around the world.

We work with partners all over the world.

The Team

In 2016, we started with the vision of making the smallest particles in the air measurable and visible – in real time. The vision became reality. With great conviction, we rely on artificial intelligence and Swiss precision work for the automatic identification of the smallest components in the air we breathe. With great passion, our team develops and produces products and solutions for monitoring bioaerosols, pollutants and other solid particles.
