Fraunhofer Institute confirms effectiveness of Cubusan air purification device
This completely new, revolutionary Sterex plasma technology kills up to 99.9% of all germs (viruses and bacteria) in the room air and on surfaces, including SARS-CoV-2 viruses and their mutations. Unlike conventional air filter systems, the room air is not sucked in and filtered. With the help of special ions, which also occur in nature and are known as the „detergent of the atmosphere”, the room air is enriched and thus permanently disinfected in real time.
In a very comprehensive test report, the Fraunhofer Institute confirms the high effectiveness against viruses such as Sars-CoV-2 on the one hand and the reduction of harmful organic compounds in the air on the other. The greatly reduced risk of infection makes it much safer for people to stay in offices, business premises, hotels, schools, restaurants, retirement homes and other enclosed spaces. For example, a 50 m room is not only disinfected within an hour, but also permanently maintains this cleanliness status despite the presence of people who emit germ-laden aerosols, without them being exposed to ozone. This means that over 10,000 people are now protected in the best possible way every day.
„The Cubusan works on the basis of Sterex technology and uses cold plasma to eliminate up to 99.99% of all bacteria, fungal spores and viruses, including SARS-Cov-2. The new development is many times superior to the short-lived FFP2 masks and, as an additional measure, significantly reduces the risk of infection even further," explains Daniel Steininger, General Manager Division Sports & Hygiene at WINTERSTEIGER AG. A single cube measuring just 19 x 19 x 19 cm creates a room with an area of approx. 50 m2 or 120 m3; any number of cubes can be set up in larger rooms. The cube is also very quiet at 32 dB, consumes less energy than a 25 W light bulb and is odorless. It fights viruses and bacteria without chemicals, ozone or UV-C. As a so-called „Plug and Play“product, it is also completely care and maintenance-free, there are no lamps or filters to replace. „Thanks to its ease of use and high efficiency, our new air purification cube will provide valuable services at the Hamburg European Open. We are convinced that with the Cubusan, in addition to wearing masks and keeping our distance, we can make an important contribution to the safety of players, visitors, employees and journalists," emphasizes Steininger.
Effectiveness exceeds FFP2 masks
Together with external research partners, the Cubusan CP-120 air disinfection device has been successfully brought to series production after just six months of development. WINTERSTEIGER also turned to the renowned Competence Center for Technical Hygiene & Applied Microbiology in Malsfeld. Its director and expert, PD Dr. med. Dipl.-Chem. Dipl-Ing. (FH) Ulrich F. Schmelz carried out the tests in the accredited laboratory „Umwelthygiene Marburg“. The laboratory is accredited according to DIN EN ISO/IEC 17025 for microbiological tests and the testing of pharmaceutical products and medical devices (DAkkS Berlin). This means that the laboratory meets an extremely high quality standard that is valid worldwide and guarantees the validity of the results obtained. Due to the speed with which the Cubusan eliminates airborne germs and its high efficiency, the microbiocidal potency of the hydroxyl radicals is up to 100 times stronger than the filter performance of FFP2 respirators.
While conventional air filter devices and air circulation systems draw in the air in the room and, depending on the system, filter it and/or then irradiate it with UV-C light, the WINTERSTEIGER air disinfection device eliminates the germs directly where they occur: continuously and evenly throughout the room. Air circulation systems and air conditioning systems also distribute germs that adhere to aerosols with the air. This increases the risk of infection.
Würfel uses „detergents of the atmosphereäre“
The Cubusan takes nature as its model and, to put it bluntly, creates lots of little summer storms. The electro-physical technology is based on the effect of hydroxyl radicals (OH). In nature, these molecules are produced, for example, by water vapor in combination with sunlight - for example after a thunderstorm, when the first rays of sunlight come through the clouds and the air is noticeably fresher and cleaner. Hydroxyl radicals are therefore also called „detergents of the atmosphereäre“. The plasma generator in the cube produces a mixture of air and cold, atmospheric plasma in which countless of these highly reactive hydroxyl radicals are formed. These are distributed evenly throughout the room via the built-in fan and natural diffusion, purifying the air of viruses, bacteria and fungal spores with an efficiency of up to 99.99%. Even if the room is briefly ventilated or a door is opened, the Cubusan continues to work reliably, as sufficient hydroxyl radicals are constantly generated. An area of at least 3.5 m per person should be available in the room and regular ventilation should continue to be practiced.
