How does the DELTRI+ technology work?  
The Luxembourg Institute of Science and Technology (LIST) has conrmed the anti-virus 
activity of DELTRI+ following in-depth laboratory tests.
 Good to know: Some high-quality face masks 
already utilise comparable technology. DELTRI+ brings 
a similar concept to the HVAC sector, suitable for 
much larger surfaces and usage times. 
What else should I know?
These are answers to the most frequently asked questions:
•  The Luxembourg Institute of Science and Technology 
(LIST) and an independent laboratory in France  
have scientically proven the DELTRI+ Technology’s 
effectiveness against biological aerosols, including 
SARS-CoV-2.
•  Deltrian has developed this technology to last over  
a commonly recommended lter life cycle prescribed 
by trusted manufacturers suitable for your type of 
application and environment, but not longer than  
12 months. We generally encourage more frequent 
lter replacements.
•  Systemair delivers the lters separately with the 
AHU for commissioning. To ensure that the virucidal 
treatment and coating does not get affected during 
transportation and storage all lters are packaged.  
The 12 months lifetime starts when you unpack and 
start using the lter.
•  The technology’s reliability ultimately depends on  
how well you generally maintain your units.
For more information, please look at our FAQ section, 
which provides more in-depth insights into the functioning 
of DELTRI+.
”We are proud to cooperate with one of the world’s 
leading ventilation companies in launching DELTRI+. 
Systemair’s technical expertise and long-term 
market knowledge have proven invaluable in the 
development of this solution. After all, we are proud 
to say that DELTRI+ can capture and inactivate 
viruses. Its effectivity is proven in dry and wet 
environments, open and closed circuits alike. In 
addition, the lters reduce the risk of transmission 
and proliferation of viruses and bacteria in the 
air. While it does not replace other preventive 
measures, we consider it a hands-on contribution  
to support a return to a more normal life.”

What do we offer?
Systemair can provide you with the following lter types:
•  ISO16890 ePM1 90% (comparable to EN 779 F9)
•  All standard AHU lter sizes and special formats for 
compact units
You can already order our DELTRI+ air lters in most of 
Europe and many other markets worldwide. 
•  Contact any of our local sales ofces. 
•  Visit our Webshop to order with the click of a button 
(only in markets where available).
Here is how and why it works:
1. As tested by the Luxembourg Institute of Science and 
Technology and an independent laboratory in France, 
DELTRI+ Technology signicantly reduces biological 
aerosols including SARS-CoV-2.
2. The treated lter surface activates on contact with  
the droplets that carry viruses.
3. After the contact time, viruses are inactivated and no 
longer infectious.
