Our passion is your healthy air! Or more precisely: Your air decontamination solutions. We develop and produce the most innovative air cleaning technology. For every industry and sector. What makes us special: We at Calistair only do what we can do best, and in our research we concentrate solely on this one technology. Our engineers, technicians, biologists and health professionals, without exception, dedicate themselves to the scalability and easy system integration of innovative indoor air treatment.
Our standard: Implementing the best of all indoor air treatments – the Calistair Technology – smoothly in your existing components and assemblies.
This makes your end products more valuable – and permanently improves safety standards for people and animals. The small version of our air disinfection technology is suitable for indoor air filtering of a passenger vehicle and the large size or version for installation in the ventilation and air-conditioning system is suitable for a hospital, a public building or a livestock farming facility.
We define the new standard for air cleanliness in the interiors of production plants, industrial buildings and other types of buildings – worldwide. There is therefore practically only one answer to the question of how chemical pollutants, viruses and other microorganisms can be destroyed permanently and sustainably: Calistair.
And if you are asking yourself why we do this: Because we can do it extremely will.
The established technologies for air decontamination – as the table below clearly shows – not only include HEPA, but also other solutions. They all perform good work across industries, but often reach clear limits. For example, HEPA filters display weaknesses, especially where smaller particles are concerned – the retention capacity of the filters reduces significantly for particle sizes between 0.03 and 0.5 micrometres. The consequence: the smallest particles remain in the air, as the blue curve in the following diagram illustrates impressively.
For your company, this can also mean that despite HEPA filters, many particles in the air are not filtered out. Accordingly, not only the potential hazard for humans increases. It can also have a negative effect on the quality of your products.
Calistair’s “secret”: It uses non-thermal catalysis, a pioneering catalysis method. The advantage: it not only destroys gases, volatile organic compounds but also microorganisms and no toxic or by-products are produced at the end of a reaction – ozone, hydrogen peroxide, radicals and similar and are no longer an issue here. In addition, the Calistair Technology makes it possible to handle air velocities of up to 5 m/s with ease. In combination with a very small pressure loss, the comparatively low energy consumption and the durability of the catalyst, these are all strong arguments in favour of use of the Calistair Technology and its integration in your industrial goods and end products.
Our R&D experts have summarised the scientific results for you. They compare the mechanical filtration and technology of Calistair. They show why HEPA filters should be supplemented or replaced by the Calistair Technology when it comes to effective destruction of airborne biological contaminations and therefore increased air cleanliness.

Without research, no progress – this is nowhere as true as it is in the natural sciences. Working with renowned institutes, we brought reputable experts on board to prove that air disinfection by the Calistair Technology destroys more than 99.4 % of the airborne coronavirus type HCoV-229E* harmful to humans effectively within 10 minutes.
The test series was based on a miniaturised prototype, which was used in a microbiological safety container with 0.54 m3 volume.
The important factor: No other aids or filters were used, only the Calistair Technology.
Further tests using a downscaled prototype, consisting of UV lamps and catalytic grids, led to the removal of 94.9 % of Staphylococcus aureus within 15 minutes.
In addition, Air & Bio without HEPA filters showed that the Gram-positive bacterium Staphylococcus epidermidis (strain reference ATCC® 14990™) was destroyed with an efficiency of 96.32 % at an air flow rate of 1000 m3/h in a single-pass.
In a test with a fungus – Aspergillus brasiliensis (strain reference ATCC® 14990™) , an efficiency of 93.59 % was determined after a single-pass at an air flow rate of 1400 m3/h and without the use of filters.
Further tests were performed by the experts at TERA Environment. Here the following average efficiency values were achieved at an air flow rate of 1000 m3/ h without HEPA filters in a single-pass.
Formaldehyde: 74 %
Acetaldehyde: 39 %
Acetone: 94 %
Heptane: 99 %
Toluene: 99 %
Acetic acid: 99 %
*The institute that performed the tests confirms that the technology invented by Calistair destroys more than 99.4 % of the human airborne coronavirus of the type HCoV-229E within 10 minutes. A miniaturised reactor (30 cm x 30 cm) in a microbiological safety container with a volume of 0.54 m³ was used in the tests. No other aids were used, such as filters, only the Calistair Technology. Coronavirus HCoV-229E is a coronavirus in the same family as SARS-CoV-2, the virus that is responsible for the COVID-19 disease.
