A HEPA air purifier with totally unique technology

Our air purifier for viruses consists of a unique filter combination to ensure it’s capturing high quantities of airborne pollution. A Flimmer filter catches most of the air pollution while a HEPA 14 filter traps tiny micro-organisms which might have got away. So unique is this idea it’s even got a patent.

Start with clean, germ-free air

Zehnder's HEPA air purifiers ensure you can breathe in clean, germ-free air by removing viruses and other harmful particles from the air. Our filters are guaranteed to capture 99.995 % of viruses, protecting you and keeping you healthy when natural ventilation is not possible.

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

The more people you get in an indoor space, the higher the chances of spreading airborne germs, including coronavirus. And the more time you 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.
  • Viruses need to be present in a certain quantity to cause infection. Outdoors, where fresh air heavily dilutes aerosols, the risk of infection is much lower than indoors.
  • The World Health Organization (WHO) states that in indoor environments, without much air movement and space to disperse them, tiny aerosols stay suspended in the air over long distances and time, increasing the risk of infection.
  • Viruses which are no longer suspended in the air fall down on to surfaces, creating another infection risk.
