CE Approval


Passed all necessary tests and achieved CE certification for a Ceiling System with LEA™ air disinfection technology

Environmental Test Campaign at DPU


A study over a period of three months with a Cleanair prototype with implemented LEA™ technology was conducted by Cleanair Project Partner Danube Private University (DPU) by Dr. Kleber and his colleagues. The study showed a strong reduction of the Cfu´s germ count, while absolutely no formation of ozone or NOx was measurable.

FDA certified testing Campaign


The graph shows the linear trend line of the prototype with LEA™ air disinfection technology and an estimate of the theoretically achievable reduction in test time provided for such tests above the detection limit of the test procedure. Based on this extrapolation, the expected reduction for a 150-minute time under the same test conditions would theoretically be 10.0 net LOG. During the test period, the ozone level was consistently below the measurement limit of 0.001 ppm.

New system prototypes manufactured


For the system layout as a ceiling panel, the 2nd generation of system prototypes, equipped with additional safety features including ozone measurement software, fault alert and maintenance signal via LEDs, continuous current measurement, as well as continuous monitoring of ambient air including measurement of CO2, air temperature and air pressure have been manufactured. These prototypes will be used for field-testing at the sites of partners DPU and INM. For the next generation of CleanAir prototypes, the addition of a particle counter is envisaged.

A warm welcome to our new partner!


We are proud to announce that the CleanAir consortium has been expanded by a new, competent partner – the Institute for virology of Medical University of Innsbruck, Austria (MUI), lead by Prof. Dr. Dorothee von Laer. MUI will be responsible for the demanding task of the execution of SARS-CoV-2 bioaerosol testing under BSL3 conditions for performance evaluation of the CleanAir system. MUI’s team leader Dr. Janine Kimpel, together with her colleagues, has already shown great competence and effort in the project and the consortium is confident that MUI will make a significant contribution to reaching project success.

Design process for dental chair system started


Besides system layout as a ceiling panel, it is envisaged to develop an air decontamination system specifically designed for installation on dental treatment chairs for effective health protection of patients and medical personnel. The design process for this system layout has begun and will be done in close cooperation with partner DPU, as a potential future operator of the planned CleanAir dental chair system.

First experimental prototype built


The first functional prototype for the CleanAir air decontamination system has been built. This early prototype will set the basis for building further prototypes, which will be used to determine the effect of the designed system concepts in the operating environment.

Functional specifications have been defined


The market-based requirements for the CleanAir system have been defined. These requirements are based on inputs from medical advisers, performing preliminary field tests, literature research, market-, and regulatory research. The gathered information will serve as the basis for the design and development of the CleanAir air decontamination system and its validation.

Testing methodology has been defined


In order to ensure that the planned air decontamination system can be tested and validated in representative environments, several existing testing methodologies and procedures have been studied and the required testing vectors for the CleanAir system have been defined. Laboratory testing for reduction of virus content in air, as well as field testing by partners IRCCS NEUROMED and Danube Private University in medical treatment rooms will be performed.

CleanAir is starting


On November 26th and 2020 CleanAir has kicked-off. 

Seven partners from Austria, Germany, Italy and Israel will cooperate to develop an innovative air decontamination system for medical facilities and public spaces.
