In the colder months we tend to spend more time in enclosed rooms thereby increasing the risk of becoming infected with viral diseases.

Olfactory adaption means that within a very short time we lose the ability to assess the air quality. As a result, it is important that we counteract this. You can significantly reduce the risk of infection from SARS-CoV-2 / Covid19 (Corona viruses) and other viral diseases by using HEPA H13 indoor air filter systems and CO2 measuring devices.

Air filters reduce the aerosols in the ambient air.

SARS-CoV-2 / Covid19 and other diseases of the lower respiratory tract are transmitted by aerosols/droplets among other things. Air purifiers with H13 HEPA filters can filter these tiny particles out of the air in a room and thus significantly reduce the risk of infection. A combination of regular ventilation and air purifiers with H13 high efficiency particulate air (HEPA) filters is the best precaution to reduce the risk of infection in enclosed spaces. H13 HEPA filters remove the tiny aerosols (<5µm) from the air, thereby improving air quality. CO2 measuring devices are a useful supplement to ventilation.

It is estimated that the risk to people in a room of infection with SARS-CoV-2 / Covid19 (Corona virus) through the presence of a super-spreader is reduced by a factor of 6 by the use of air filters with H13 HEPA filter technology.

Control and improve the air quality in your office, home, classroom, etc. with the following measures:

  • Correct and regular ventilation/cross ventilation
  • CO2 measuring devices/monitors that supplement ventilation
  • Air purifier/air filter with H13 or H14 high efficiency particulate air (HEPA) filters

How to calculate the filter performance in m³/h for a given room size:

An ambient air filter should be able to filter the air in a room at least 2x an hour in order to significantly reduce the concentration of aerosols and particles. It's therefore very easy to calculate the required filter performance:

To calculate the volume of air in a room in cubic metres, take the length x width x height of the room. Multiply this result by 2 and you have calculated the required filter performance in m³/h for your room.

For example:

Length: 5m Width: 4m Height 2.5m

5m x 4m x 2.5m = 50m³

50m³ x 2 (per hour) = 100m³/h.

For classrooms or other rooms where several people may gather, we recommend that you calculate the air purifier performance requirement as 5 to 6 times the room volume.

For example:

For a room volume of 50m³, the air purifier used should have a capacity of at least 300m³/h.
