Infiniti believes the quality of the air within a car's cabin has a direct bearing on the well-being of driver and passengers. Which is why it developed Forest Air, Infiniti's most advanced climate control system that makes its debut in the Infiniti M Line (depending on model). The system offers unrivalled temperature, humidity and pollution control while re-creating the gentle breezes and subtle scents of an environment known to promote alertness and relieve stress: the forest.
