Which household cleaner can disinfect against COVID-19?

Any household cleaner containing bleach or at least 70 percent alcohol should kill SARS-CoV-2, the virus that causes COVID-19.

Are public systems for disinfecting individuals (spraying in tunnels or chambers) recommended?

Spraying of individuals with disinfectants (such as in a tunnel, cabinet, or chamber) is not recommended under any circumstances. This practice could be physically and psychologically harmful and would not reduce an infected person’s ability to spread the virus through droplets or contact. Even if someone who is infected with COVID-19 goes through a disinfection tunnel or chamber, as soon as they start speaking, coughing or sneezing they can still spread the virus.

How does ozone disinfection work?

Like chlorine and chlorine dioxide, ozone disinfects by oxidation. It undergoes oxidation to affect the reproduction and metabolism of microorganisms. This results in a reduction of pathogen populations and disinfected water and produce surfaces. Ozone’s oxidation power is higher than both chlorine dioxide and chlorine.

How much ozone do I need to treat water?

In drinking water applications the H2S is often removed to make the water more palatable. The theoretical amount of ozone required to remove H2S is 3 mg ozone/mg H2S, but in practice and excess of ozone is used (4 mg ozone/mg H2S). The H2S is oxidized to sulfate, a soluble salt.
