this is more important than ever!

  • Wavebionix® is the first ventilation filter in the world to be tested with active viruses.
  • It can be easily installed in existing ventilation systems.
  • It removes 97.2% of all viruses and germs from indoor air.
  • It thus reduces the risk of infection in buildings to an absolute minimum!

Kappa Wavebionix® is ​​a new and innovative filter element that has a highly effective separation of viruses and aerosols. 

The high filtration effect has been confirmed by an independent, accredited Austrian test laboratory with a "Viral Filtration Efficiency" of 97.2%.

During development, we made sure that the filter elements are able to be installed in almost any ventilation system.

Therefore, it is possible to upgrade existing ventilation systems to a protective system against possible virus transmission without any modifications.

As a result, the risk of infection indoors is reduced to a minimum.

Do you own a hotel, a restaurant or a wellness facility?

...and could not receive guests for months?

Do you run a fitness studio, a cinema or a cultural facility?

…and had to close because of the pandemic?

Are you a business owner in industry or commerce?

Would you like to know more?
The virus filtration efficiency of the Wavebionix® is 97.2%, which means that 97.2% of all viruses are eliminated from indoor air. In addition, the Wavebionix® removes aerosols, fine dust and bacteria from the air.

These values are confirmed by certification from the Austrian Research Institute for Chemistry and Technology in Vienna.

What it took: Three test runs with active viruses and aerosols!

This means: The risk of infection in buildings (hotels, fitness studios, companies, restaurants, event locations, etc.) when using the Wavebionix® is extremely low. This is important because we know that the pandemic cannot be brought under control with hygiene, social distancing and masks. But even after the pandemic, we spend 2/3 of our lives indoors and literally "consume" 15 kg of air every day.

What could be more natural than keeping the air in buildings clean and healthy?

From our years of experience, we know that the most effective way to combat viruses, pathogens, fine dusts and aerosols in buildings and rooms is to ventilate frequently and thoroughly. This is best done with a modern ventilation system. The Wavebionix® turns existing ventilation systems into protective shields against airborne pathogens - it is the cost-sensitive "tuning" for your ventilation system and thus enormously minimises the risk of infection.


Filter tests are generally carried out in accordance with the filter test standards with so-called A2 fine dust (sand dust, dolomite dust). Ventilation filters, but also FFP2 or FFP3 protective masks are tested according to this procedure.

However, a filter test with a type of sand dust has little informative value about the filtration of microorganisms or viruses in the nano range.

Until now, there was no test method for measuring virus separation efficiency. Therefore, together with our research partners, we have developed a test procedure that makes it possible to test under real-life conditions.

In this process, viruses are applied to aerosols - just as happens in reality - and for the first time an entire filter element (not just a filter material sample) is exposed to the aerosol-virus mixture.

Finally, the viral load in the clean gas is analysed and the virus removal rate is determined from this. The test is repeated several times in order to obtain a valid result. The viruses used have a size of 28 nm (nanometre = 1 millionth of a millimetre) and are thus 5 times smaller than the coronavirus.

The test demonstrates a virus filtration efficiency of 97.2%, which is even higher for the SARS-CoV-2 virus.

the city of Styria (city hall, test street) as well as the
Lower Austrian Chamber of Agriculture (administration building St. Pölten) are currently already using the Wavebionix®.

About us

As a visionary, Kappa started thinking about healthy indoor air as early as 2019 and developed the Wavebionix®. In 2020, the company was suddenly centre stage (keyword: Covid-19) and a trendsetter. Aerosol research and air pollution control have been part of Kappa Filter Systems' DNA since its founding in 1993. This distinguishes the supplier from many other companies currently entering the market, which offer less sophisticated products or products that have only been tested for dust.


Kappa Filter Systems GmbH is part of the family-run HAINZL/Kappa/Aquasys group of companies based in Styria-Gleink in Upper Austria. Founded in 1993, Kappa is now a leading international manufacturer of systems and lines for industrial air pollution control and energy recovery.

Production sites are located in Linz and branches in Düsseldorf and Dresden. The group has over 800 employees, 110 of whom work at Kappa. Every year, Kappa invests around 8% of its turnover in R&D. The export rate is around 75%. The turnover in 2020 was 25 million euros (group turnover 160 million euros).


Zero Emissions and Zero Waste of Energy describe the company's guiding principle: to always achieve the best air quality for customers with the greatest possible economy and efficient use of resources.
