Hi Courtney,

You may consider buying a 3M mask. I bought a 6000 series mask
(re-usable)some three years ago, on which one may attach dust filters
(various particulate sizes), but also gas and vapour filters.
The re-usable mask (half face) costs about EUR 60 if I recall well; the
gas filters will probably cost some EUR 40 (inform at your local
supplier).
Although I wear spectacles, I do not find the mask annoying.
Hint: Although the gas filters (I believe they're filled with some
active carbon) are supposed to last for a ltd timespan only, you may
boost their life by storing them in a Tupperware-like box.
I hope it helps you,
kind regards,

Arjen Mulder.
