And if it is, you'll have a much harder time breathing.

  I have been wearing N95 when biking in the city for a year now. It is great, it is not difficult to breath at all (I am really incredulous at people making that claim), and it provides a measurable difference in the air I breath (a nasty but efficient way to measure that is looking at your snot if you bike while having a cold).

    Thank you, I was repeating something I've heard, I do recall trying such a mask before covid in summer and finding it a bit uncomfortable, but maybe it varies. I'm quite interested in better breathing when riding my bike when air quality ocassionaly drops so I'll give it a try!

      In the particularly hot months I have had to use small piece of cloth under the mask so I can remove it after my commute and not have a humid mask on my face, but that was the only issue I had. Even with the extra cloth I did not have trouble breathing (I specifically try to not exert too much effort when commuting on a bike because the sweat on my back would be a much worse source of discomfort than the mask)
