Why clean air matters – essential for human health and industrial efficiency
Clean air is one of the most fundamental necessities for human life, just like clean water and nutritious food. According to the WHO, 99% of the global population is exposed to air that exceeds recommended pollution levels. Air pollution is associated with approximately seven million premature deaths and a range of serious health conditions every year, along with significant economic losses. Furthermore, the transmission of airborne diseases, such as SARS-CoV-2, measles and influenza, poses a threat to human health.
Beyond its health impacts, poor air quality can also disrupt critical industrial processes. Air pollutants can severely damage sensitive equipment, such as gas turbines or fuel cells, leading to costly breakdowns and downtime.
That’s why we at VTT are dedicated to developing clean air innovations that safeguard both human health and industrial efficiency.
Healthy air for people: clean air solutions for indoor spaces
Sustainable solutions for creating healthy and resilient indoor spaces are more important than ever — especially in light of the recent COVID-19 pandemic. That’s why we assist companies and organisations in building resilience against future challenges.
With our extensive experience and innovative approach, we help you develop solutions that optimise indoor air quality by reducing fine particles and other harmful substances, and by minimising the spread of airborne pathogens. We support seamless integration with building technologies, such as HVAC systems, using disruptive technology to enhance energy efficiency.
Our expertise lies in airborne contamination control in products and processes, advanced air filtration technologies and airflow analysis, exposure control and occupational hygiene. We use computational fluid dynamics (CFD) and precise measurement techniques. We also conduct performance evaluations of air cleaners, particle and gas filter media and gas filters (also known as molecular filters), as well as develop filter and filter measurement systems.
We can help you:
- Validate your air quality solutions with tailored measurement systems designed for in-house development and quality assurance.
- Leverage our innovative air cleaning R&D service platform, which combines experimental lab facilities, advanced simulation capabilities and field measurement expertise. This comprehensive approach provides you with solutions that ensure optimal product performance.
- Accelerate your product development efforts with VTT’s patented technologies, improving your competitive edge.
Clean air for processes: ensuring consistent performance in industrial operations
Disruptions in industrial processes can lead to significant financial losses. Effective air filtration is critical in environments such as gas turbine power plants, where air intake filters must protect the most sensitive and expensive parts of the power engine from erosion, fouling and corrosion. Contaminated air can quickly corrode turbine parts, leading to reduced efficiency or even complete shutdowns. Similar challenges also need to be solved in emerging energy applications like fuel cells, hydrogen and biomass.
We can help you:
- Ensure your product performs consistently even in harsh industrial environments through rigorous testing that replicates challenging conditions.
- Accelerate your R&D process for air filtration technology while minimising in-house investments.
- Guarantee durability in coastal and offshore areas, where salt and moisture can quickly damage sensitive components.
- Provide performance assurance for your products when standard testing isn’t enough.
We provide a comprehensive evaluation package for air filters used in power plant applications. This evaluation package encompasses everything from co-developing filters and establishing evaluation procedures to delivering tailored measurement systems for in-house development and quality assurance. Our specialty lies in assessing air filters in humid conditions, combining both modelling and experimental approaches to ensure performance in real-world environments.
Reliable emission measurements
In addition to clean air solutions and technologies, VTT boasts decades of experience in emission measurement and quality assurance. We collaborate with both national and international clients and partners.
As an impartial research institute, we have conducted intercomparison measurements for both Finnish and foreign emission measurement teams since the 1980s. We have extensive expertise in characterising emissions from power plants, industrial processes, ship engines and other point sources.
Moreover, we offer a research platform for analyser manufacturers to innovate and test new emission measurement technologies, ensuring that the highest standards are met in both laboratory and field environments.
Chemical and biological decontamination of sensitive platforms
Chemical and biological (CB) threats require decontamination solutions that are fast, effective and safe for sensitive platforms and environments. VTT develops and demonstrates advanced decontamination technologies that support defence and security actors in restoring operational capability after CB exposure. The benefits include:
Rapid and efficient CB decontamination
Noncorrosive solutions for sensitive platforms
Faster return to operational use
Scientifically validated performance.
Our work focuses especially on noncorrosive and platform-compatible decontamination methods, enabling the treatment of vehicles, equipment and enclosed spaces without compromising materials or electronics.

Customer cases
KONE, a leader in the elevator and escalator industry, partnered with VTT to enhance the health and safety of their elevators. Through the development of a new air extraction design that features a modified air supply and an increased ventilation rate, KONE significantly reduced the number of aerosols while improving thermal conditions within the elevator. This collaboration has resulted in a verified solution that not only improves health and safety but also enhances the overall comfort of KONE's products.
A heavy-duty gas turbine air intake filter was evaluated using a laboratory test designed to replicate harsh coastal conditions, successfully demonstrating its water and salt collection performance. To meet the project requirements, VTT ramped up and integrated new testing capabilities. This evaluation was one of eleven tests conducted by Camfil as part of an extensive validation process. Following successful results, these high-performance filters are now being delivered to the turbine OEM.
