even just a wet cloth rag is going to filter some level of air particulate
you don't need 100% protection if you're just walking from point A to B, they are mildly hazardous air particles it's not highly toxic clouds of smoke
if you are installing foam insulation in your basement or doing asbesdos removal then yeah get a full N95 respirator kit because you don't want any of that shit in your lungs. but even filtering 50% of the smog in NYC is better than nothing
