More than 99.99% of influenza A virus particles attached to a plastic carrier were inactivated by exposure to 10 ppm ( V/V ) - ozone gas for 210 min at 23 to 29°C and a relative humidity of 64 to 65%. When the virus was exposed to 20 ppm ( V/V ) - ozone gas for 150 min, more than 99.999% was inactivated. In contrast, the virus remained active after 10 hours under similar conditions without ozone gas. These data suggest that office disinfection against influenza viruses might be accomplished by… Expand

Effectiveness of Ozone Gas on Airborne Virus Inactivation in Enclosed Spaces: A Review Study
ABSTRACT Due to the recent outbreak of COVID-19, the problem of protecting the individual against airborne transmission has become of great importance. This transmission occurs when virus-containingExpand
Low ozone concentration and negative ions for rapid SARS-CoV-2 inactivation
TLDR
The studies suggest that ICON3 may have the potential for use in the disinfection of SARS-CoV-2 in indoor environments in the absence of individuals and animals, under properly controlled and monitored safety conditions. Expand
Disinfection of N95 Respirators with Ozone
TLDR
This study demonstrates that an ozone application achieves a high level of disinfection against PsA, a vegetative bacteria that the CDC identifies as more difficult to kill than medium sized viruses such as SARS-CoV-2 (Covid-19). Expand
Disinfection of Pseudomonas aeruginosa from N95 respirators with ozone: a pilot study
TLDR
Ozone exposure disinfected 3M 1870 N95 respirators heavily inoculated with P. aeruginosa and suggested that ozone is a feasible strategy to disinfect N 95 respirators for reuse during this and future pandemics. Expand
Ozone potential to fight against SAR-COV-2 pandemic: facts and research needs
TLDR
Conservative dosages and times to inactivate the SARS-CoV-2 are estimated and can be used for reducing significantly the viral load although for assuring a safe disinfection, the effective dosages under different conditions need to be confirmed with experimental data. Expand
Can ozone inactivate SARS-CoV-2? A review of mechanisms and performance on viruses
TLDR
This critical review examined the most relevant information available regarding ozone application in gas-phase for different viruses inactivation, and pointed towards envelope alteration as the main reaction pathway for enveloped viruses, such as is the case of SARS-CoV-2. Expand
PRELIMINARY INDICATIONS FOR THE USE OF OZONE AS AIR AND SURFACE DISINFECTANT IN THE CONJUNCTURE OF COVID-19
The main objective of the present document is to review the available scientific information on ozone virucidal activity in order to extrapolate quantitative data for the use of ozone in theExpand

TLDR
A new Safety O3 Emission (SOE) method is proposed to increase indoor O3 to levels that inhibit the transmission of the SARS-CoV-2 but are not harmful for humans that could serve as timely and low-cost solution for suppressing COVID-19 outbreaks throughout the world. Expand
Characterization of a novel, low-cost, scalable ozone gas system for sterilization of N95 respirators and other COVID-19 related use cases.
TLDR
Deployment of this sterilization system during the ongoing pandemic reduces the risk of COVID-19 community transmission while conserving monetary resources otherwise spent on the continuous purchase of disposable face coverings. Expand
Impact of Pollution, Climate, and Sociodemographic Factors on Spatiotemporal Dynamics of Seasonal Respiratory Viruses
TLDR
The authors present a review of the literature on seasonal viruses, their annual diffusion through populations, and factors that reduce or enhance their seasonal spread and offer suggestions for targeted interventions to reduce the disease burden from seasonal viruses. Expand
