None of those masks actually filter anything other than maybe some bugs from your face. If they did then you would need to be replacing a surgical filter from them after 4 hours of full use or 12 hours after any partial use.
What you should really consider is how to keep yourself from getting road rage and getting into a fight at the stop lights.
You will likely be somewhere without the loluneconomic bike lanes so you will occupy a whole lane like a car does.
Many motorists don't understand why you might need that and that it is in fact 100% legal and recommended instead of going on sidewalks or veering between lanes. They will honk at you and some might swear.
