AmbiCube - effective protection against indirect contamination in closed rooms
Geplaatst op 07-04-2021
Recent study confirms: air purifiers effectively protect against indirect contamination in enclosed spaces.
As exclusive distributor of the German company Keller Lufttechnik, the family business Lybover, with branches in Waregem and Bruges, is well placed to interpret the recent appeal of Belgian scientists for better air quality. Recent research by scientists of the University of Stuttgart shows the high effectiveness of air purifiers with so-called HEPA H14 filters.
Currently, our country is confronted with more contagious Coronavirus variants that make us even more cautious. At the same time, contact restrictions and the closure of institutions and businesses are having increasingly serious social, health and economic side effects. It is therefore all the more important to make use of existing opportunities to make it less dangerous for several people to stay together in an enclosed space. Opening windows and doors or merely using a mechanical system is usually not enough.
Last year, Keller Lufttechnik, a partner of Lybover, developed a mobile air purification device called AmbiCube for this purpose. This device very effectively removes viruses from the air and prevents the accumulation of aerosols - minuscule droplets of saliva in the air. This has been confirmed by a recent study at the University of Stuttgart. The Institute for Sanitary Technology, Water Quality and Waste Management tested the AmbiCube air purifier from Keller Lufttechnik with real pathogens. The results speak for themselves: the device filters 99.982 percent of viruses out of the room air. This innovation is now a proven technology with more than 1,000 installations.
99.982 percent effective: test with real viruses
The high efficiency of the AmbiCube is due to a so-called HEPA H14 filter. Such HEPA filters have been certified for a long time and are used, for example, in hospitals. They reliably filter small particles from the air - in addition to viruses, these include bacteria, pollen, spores and fine dust. In the past, scientists proved their effectiveness by producing small particles of different sizes with silicone oils and testing the filters with them. Because oil reacts differently from a virus, real pathogens were used in this recent research. phi6 bacteriophages, which are harmless to humans, were used in these recent experiments. These are viruses that only infect bacteria. The results are convincing. The study shows that the AmbiCube works very well. An efficiency of 99.982 percent is far above what other filters or processes offer.
Where are air purifiers used?
Air purifiers are particularly recommended in all indoor spaces that are used by multiple people: These can be offices and meeting rooms, medical practices and nursing homes, day-care centres and schools, hairdressing salons, shops, gyms, canteens or restaurants, for example. The AmbiCube cleans the room air more than six times an hour. High-quality room air cleaners make such places much safer by significantly reducing the indirect risk of infection from virus-carrying liquid particles, called aerosols. Such particles can remain suspended in room air for hours and, according to current knowledge, are responsible for about 45 per cent of infections. However, direct infection through coughing up (droplet infection) or through contact with a virus-contaminated object is still possible, even in rooms with filtered room air. It is therefore important to continue to observe all known protective and hygienic measures.
Lybover is pleased that Belgian scientists, following the German research, confirm that such air purifiers are the right long-term solution for the protection of people in enclosed spaces.
