A respro doesn't filter out PM2.5s or NOx does it?
apparently some of their masks can do even better than 2.5.
nothing is going to be perfect. But speaking as a relatively fast cyclist bombing through the city everyday, and as one with asthma I've not noticed any bad issues with my lungs since using it..
Started cycling in the city (London) and it gave me asthma.
Got respro. There really isn't an alternative to choose from, but with some adjustments and extras it works well. No asthma since.
I commute in London as well and wear a respro.
I can't offer any evidence but when I put a new filter in, it's white and when I replace it three months later, it's a dirty dark shade of grey.
One long term effect of the pollution us that I have started to become susceptible to a mild dose of hay fever as soon as the weather turns. Thankfully it's easily sorted and goes away but I have neve has any allergies.
I bike-commute in Manila. Undoubtedly worse than London in terms of air quality. So far, no tonsillitis...but this is a your-mileage-may-vary kind of thing, I would assume.
