Filter

A lot of cyclists in London wear masks, I guess the masks are supposed to filter the filthy air we breathe. Although I'm informed that all these masks do is filter out the really big particles and mess with your complexion.

Anyway, I was walking back to the station after work and saw a bloke on a bicycle at the traffic lights. He wasn't wearing a mask, instead he had a cigarette drooping out of his mouth. Different kind of filter, I suppose.
