ABSTRACT
Ultraviolet (UV) and ozonization innovation are effective physical cycles for the purification of microorganisms and infections. Powerful purification techniques are needed to deal with the COVID-19 pandemic. This section dissects the purification component of UV and ozone and surveys countless examinations on the inactivation of comparable COVID-19, for example, SARS-CoV and MERS-CoV by UV and ozone. At the end of this section, the possibility of applying UV and ozone to inactivate COVID-19 was examined.
