High protection against coronavirus, which can reach up to 93%, is provided by special devices for air disinfection, which are widely used abroad, as evidenced by recent studies. And it is possible that soon we will see them in Greece, in the metro and buses. They have already received the “blessing” of the country’s chief epidemiologist, Sotiris Tsiodras.
The government, with scientific support from the Aristotle University of Thessaloniki, is exploring the possibility of equipping public transport, metro and buses with air disinfection devices. Demosthenes Sarigiannis, professor of environmental engineering at the Aristotle University of Thessaloniki, told iatropedia.gr about this.
With the Delta mutation increasing the risk of indoor over-transmission by 18 times, which we will be exposed to more and more as the weather gets colder, the government is considering ways to reduce the epidemiological burden in crowded public places, especially on public transport.
OASA has already contacted AUTh’s Environmental Engineering Department for specifications for the delivery of these mechanisms. As an experiment, the devices were put into operation on the KTEL bus lines in Oreokastro (Thessaloniki).
Air disinfection devices: how they neutralize coronavirus
The devices work in two ways: they either “trap” or “inactivate” particles of the coronavirus. There are two types of technologies used:
Air filters, the simplest technology. These are devices that absorb air from the atmosphere and, through special high-precision HEPA filters that are inside, trap very small particles of the coronavirus.
Ultraviolet devices – This technology uses ultraviolet radiation to “inactivate” the protein coat of the virus by radiation.
