I am going to Beijing for business for 2 weeks, and I want to experience running in a different country, but I heard Beijing's air quality is really bad especially with the smog. But have a respirator would be fine right?
I'm bored this morning so I did a little research this morning about this. An n95+ mask from 3m will probably work. My own experience with these is that it's easy to break the seal when doing activities. It's still better than nothing. The reusable ones are better for fit and comfort. They are like $50 though. Mark Zuckerberg famously ran without one but was mocked for it. Good luck. I might keep it to the hotel gym, but if you love running you're probably ok with a good respirator.
