Just wonder if anyone has experience in using respro pollution mask and could give me some suggestion. There are various model of respro mask and not sure which one I should pick for my commute.
What's your commute like, fred?
Spent nearly 10 years in the safety industry specialising in respiratory protection - 2 words: don't bother. They simply don't fit well enough to you face as the air takes the path of least resistance i.e. The big gap around your nose.
Sorry didn't see this post before - I did actually do a review on the respro mask (a bit tongue in cheek)and the alternatives.
Not exhaustive but it may give some clues.
