Review of air disinfection approaches and proposal for thermal inactivation of airborne viruses as a life-style and an instrument to fight pandemics

Electrohydrodynamic devices for ionic wind generation and airborne positive‐strand RNA viruses inactivation by nonthermal atmospheric plasma

“…Therefore, these types of filters generate large pressure drops that must be compensated for by using expensive and noisy fans. [33,34] Ultraviolet-C (UV-C) disinfection has been studied and implemented as a surface treatment, However, its potential is reduced in air, as the residence times of particulate matter are not sufficient. UV-C radiation can cause health risks and should therefore not be used in the presence of people.…”

“…They also require an external element to generate the airflow to be treated. [33][34][35][36] EHD technology of nonthermal atmospheric plasma generation by corona discharge is presented as an efficient technology for the reduction of pathogenic compounds and particles in the environment, without the need to use fans to generate airflow, without noise or vibrations, and with low energy consumption. One of the main advantages of this technology is that it can be easily produced from air and electricity, providing a lower-cost disinfection solution without the expense and logistics of maintaining it.…”

COVID-19 pandemic lesson learned- critical parameters and research needs for UVC inactivation of viral aerosols

“…These include techniques such as germicidal ultraviolet (UVC) ( Heßling et al, 2020 ), filtration, nanomaterials ( Li et al, Mar. 2021 ), ventilation ( Vlaskin, Feb. 2022 ), plasma inactivation ( Filipić et al, Nov. 2020 ), photochemical oxidation ( Habibi-Yangjeh et al, Nov. 2020 )and essential oils. A recent review reports on the advantages and limitations of these techniques.…”

Solar energy assisted thermal treatment model to decontaminate airborne viruses in hospital

“…The evolution of airborne viruses shown in Fig. 1 and are as follows: Avian influenza A virus (AIV), Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-1 and SARS-CoV-2), Middle East Respiratory Syndrome Coronavirus (MERS-CoV), Mouse Hepatitis Virus (MHV), and Transmissible gastroenteritis virus (TGEV) [4] , [5] , [6] . An outbreak of the novel H7N9 influenza virus began in eastern China in March 2013 and affected humans severely [6] .…”
