After a short ride (1/2 hour) in dusty conditions I noticed that the wingnut holding the airfilter in place had come loose causing the airfilter to break it's seal and allow dust to enter where it shouldn't 
The conicle filter (metal) didn't seem to have alot of dust on it however I'm worried about the affect of what occured.
Should I ......
a) Be concerned as I've allowed nasties into the engine reducing engine life or worse.
or
b) Dry my eyes and stop being a womens blouse as it's unlikely any damage has been caused?
