if the building is 100 years old, it is unlikely to really be a ventilation
problem. There could be all kinds of mold spores, insect dander, etc. up

you may have allergies to some of it.

If it is particulates causing the trouble, an electrostatic air cleaner might
You didn't say what sort of heat (beyond hot air)- could there be exhaust
fumes getting into the attic from an old flue or some other studio?
If you do use the forced air vent, it can be professionally cleaned before it
blows crud all over.
Just my initial thoughts- I'm no expert.
