So resin fumes are not toxic, they are annoying and if you are sensitive to them, a better solution is to vent the fumes outside if possible.
Masks become very expensive as the cartridge's need to be replaced monthly and you need to store them properly between uses. It is highly recommended that if you are that concerned about fumes, you should get fit tested and have your doc get ya a spirometer test to make sure you dont have underling conditions as a mask really stresses heart and lungs.
Please consult the SDS for your resin, MANY sites are alarmist and overstate resin hazards. Gloves, goggles when poping stuff off is the PPE you need, if sensitive to odor, vent the fumes if possible, else print in an enclosure with a big ass carbon filter recycling the air should resolve any issues.
