micronAir ® Filter

Filtration solution for buses

Active protection against viruses and bacteria

Passenger health is a top priority for bus manufacturers and operators.

This is especially true against the background of the worldwide Covid-19 pandemic. According to current findings, frequent air exchange significantly reduces the risk of spreading viruses through airborne transmission. Thus, the ventilation and air conditioning system in buses is currently of particular importance.


  • Simple installation
  • Current filters can be exchanged 1:1 with micronAir® blue filter
  • Suitable for all air-conducting components (roof air conditioner, front box, recirculation filter)
  • No additional components
  • No change to the software

Filters provide additional safety

  • Highly efficient filters clean the ambient air
  • The fresh air taken in from outside
