A world first, the Volvo Air Quality System together with the mechanical filter, stops up to 95% of all hazardous PM 2.5 (particulate matter)Â
from entering the cabin..
Additionally, the levels of PM 2.5 particles in the cabin are constantly being   monitored   by   optical   sensor   and   the   cabin performance is visualized in the vehicles' center display.   SoÂ

you can always feel reassured that the air you breathe inside the car is as clean and healthy as possible
You can also clean the cabin air from particles and gases
before you enter your Volvo! The system will activate a 2-minute blowout of the cabin and then a 3-minute recirculation will clean the cabin from particles. PM 2.5 = <25 ug/m3 (Micrograms per Cubic Meter of Air), considered ideal interior air quality.
