I've just been out sanding the edges of some mouldings and I took the usual dust mask precaution (Moldex 2405 CE121) and I've just blown black bogies!  It wasn't really bad but this sort of thing bothers me.  What mask should I be using?

Although the full face mask is a bit overkill, it is cool, and may come in handy in some applications!

I use this one and feel completely safe, you cant smell any dust or vapours what so ever... I polyestered large areas in a pool, where the vapours stay trapped and i was fine for hours in there. They offer a range of different filters.
