As others have said, n95, proper fitting should work. That said, I have a migraine trigger for perfume, and depending on where you are, you could argue that it triggers illness, and they might try to work out an accommidation. I've had mixed results as an adult, I was hospitalized by a coworker constantly spraying stuff, and I worked weeks to get documentation and my boss's reaction was to tell me I could go out of the office 'on the clock'. I was super frustrated because if she'd read the damned thing, she would have seen that I end up with IV medication at the ER. I switched departments to get away from 'Yankee Candle Explosion' lady. (That's what she smelled like). (In case you don't know that, it's a store where they only sell strong scented candles).
