Mask while printing.

I want to buy mars 5 ultra. I want to have printer in same room where I work. It's necessary to wear mask whole time? Or it's ok to wear it just when working with liquid resin, opening printer and curing?

I am ok to wear it when I work with resin. But i can't have it on face 12 hours a day bcs my printer is printing 12 hours.

Are filters on printer enough to be safe while printer is printing?
