I've had a wheezy chest for a couple of weeks now, and I've decided
it's down to my Bristol commute (the air was particularly bad this
morning, but we're probably far enough from Hemel Hemstead for it to be
purely local).

Wiggle have got some scary looking masks, chap at work suggested going
down B&Q and getting decorators' masks. Any suggestions? For £25 I'd
want to wear something I'm comfortable in.
