I commuted with a Respro mask for four years when I lived in Jakarta, Indonesia (lots of vehicles, lots of air pollution). My notes
1. I felt much better wearing the mask than not. I felt like I had inhaled a huge cigar by the time I got home without the mask.
2. I had no problem getting enough air through the filters when the mask was dry.
3. Jakarta is hot and I sweat a lot anyway. As the mask soaked it became hard to breathe through. I could usually make it to work or home before it became a problem but very occasionally I would have to take the mask off due to a delay. For me the limit was 30 minutes. There are too many factors such as temperature, humidity, exertion level, etcetera, for that number to be repeatable.
4. Soaking issue aside I did not find the mask to be unpleasant. I’d say give it a shot.
