Respirator filters - what's in them?

I'm curious as to what the filters in B&Q respirators contain. Their
website being crap, I can't find a link, but I refer to the masks with a
rubber bit that fits over mouth and nose, with two round filters on
either side - one for dust and the other for vapour.
I tend to get shortness of breath from solvent and paint fumes. This
week I had it particularly badly (still have, in fact), so I bought one
of the above. The first time I used it, I found that after breathing
through it for a few minutes, I could expand my lungs a lot better. The
effect didn't last for long after I stopped wearing it.
Charcoal?
So I'm left wondering what's in the filters, and whether something there
is acting as a bronchiodilator.
That would make it medicinal though surely? And thus out of B&Qs realm.
I think my current episode is connected to naphtha in wood dye, so I'm
using water-based from now on.
Cheers
Richard
