Kärcher steam cleaners against the coronavirus
Hygienic cleanliness with steam: 99.999% of enveloped viruses are eliminated*
Kills up to 99.999% of coronavirus.* And bacteria.**
Kärcher arranged to have the effectiveness of its steam cleaners in fighting viruses tested in an independent laboratory. The result: if used properly, the machines remove up to 99.999% of enveloped viruses*, such as the coronavirus or influenza, and 99.99% of common household bacteria** from hard surfaces. As at the present time disinfectants are to be reserved primarily for outpatient and inpatient care, steam cleaners can make a valuable contribution to general hygiene – both in private households and in commercial and industrial use.
Enveloped viruses such as the coronavirus SARS-CoV-2 can be neutralised with high temperatures. As viruses are not germs or living organisms, experts also talk about virus inactivation. In the laboratory a certified test virus (Modified-Vaccinia-Ankara-Virus), which is representative for enveloped viruses, was distributed on a hard surface. This area was then cleaned with the hand nozzle of a steam cleaner and the appropriate microfibre pad. It was demonstrated that a significant reduction of up to 99.999% of the viruses could be achieved at maximum steam pressure and with a cleaning duration of 30 seconds on one area.
