Does driving with a dirty air filter affect the pollution produced by the vehicle?
A)No, it only affects fuel consumption.
B)Yes.Correct
C)Yes, pollution will be lower as less air enters the engine.
An air filter that is dirty (dust, insects, impurities,...) prevents all the air the engine needs for optimal performance from entering, increasing fuel consumption and pollution.
For this reason it is important to check it periodically, taking into account that it gets dirtier in summer than in winter.
