Start with clean, germ-free air

Zehnder Virus Shield HEPA air filtration systems remove viruses and other harmful particles from the air, ensuring you can breathe in clean, germ-free air. Our filters are guaranteed to capture 99.995 % of viruses, protecting keeping you healthy when natural ventilation isn’t an option.

Did you know over 99 % of all virus infections happen indoors?

The more people that gatherin an indoor space, the higher the chances of spreading airborne germs, including coronavirus. And the more time people spend in that space only increases the likelihood of infection. In fact scientists have revealed that 99.05 % of all infections occur indoors.

Natural ventilation helps reduce the risk, but that’s not always possible. Social distancing, face masks, and hand washing help to some extent, but aren’t always enough. The only efficient solution is to clean the air in closed spaces – with an efficient HEPA air purifier for viruses.

How viruses spread
  • Viruses spread in the air by hitching a ride on aerosols. One way they pass from person to person is on the aerosol droplets we produce when we cough, sneeze, speak or sing.
  • There must be a certain quantity of viruses to cause infection. Risk of infection is much higher indoors than outdoors, where fresh air heavily dilutes aerosols.
  • The World Health Organization (WHO) states that indoors, without much air movement and space, tiny aerosols stay suspended in the air over long distances and time, increasing the risk of infection.
  • Viruses that are no longer suspended in the air fall down on to surfaces, creating another infection risk.
