Why is clean air in the car interior so important?
The air inside the vehicle can be up to five times more polluted than the outside air. Fine dust, aerosols, pollen, bacteria, microspores and even toxic gases enter the vehicle interior via the ventilation system. These substances can:
- Trigger allergies and respiratory problems
- Negatively affect concentration and well-being
- Increase health risks
With the micronAir blue premium automobile filter, the air in the vehicle remains clean and allergen-free.

How the micronAir blue car filter works
Four filter layers for the best possible air quality in the car
1. Particle filter
- Stops PM10 coarse dust, industrial dust and pollen
- Keeps dirt particles from entering the vehicle
2. Fine dust filter
- Traps the smallest particles and harmful microparticles
- Protects against the entry of PM2.5 fine dust and microorganisms such as mold spores
3. Activated carbon layer
- Blocks harmful gases and emissions
- Reduces unpleasant odors in the vehicle interior
4. Bio-functional layer
- Scientifically tested technology without nano-silver with long-term effect
- Inactivates trapped allergens & aerosols
