From The Guardian: (I suggest you Click through & read the whole article) "It’s a scenario familiar to any urban cyclist: you’re stuck behind a fume-belching bus or taxi, a choking diesel aroma wafting through your lungs. You think: is this really the healthy option? The good, if simple, answer from pollution experts is: yes. Cycling does remain many, ...

There are two points to consider. As explained by @renesis even though you are exposed to pollutants, your overall exposure does not appear to differ significantly from car drivers (note the study was carried out in Copenhagen, I am not sure automotive how pollution regulations compare to the US). Because you are also getting exercise, your overall health ...

I know of at least one peer-reviewed article which shows that wearing a (proper) filtering facemask does have noticeable effects on one's vital signs compared to when not wearing a facemask. However, some people still say that they make very little difference in terms of long-term health effects. Moreover, the actual quality of the "filtering" of masks ...

I've worn the respro in Beijing for about a year where the air pollution apparently causes lung cancer. Of course, that is a long term effect that is hard to measure immediately, but I can say that the air smells much cleaner and I "feel" better after riding through traffic with the mask on as opposed to without it. Your face gets a bit sweaty, but it can be ...

Trials on the N95 concluded that it didn't really do a good job filtering chemical pollution. http://www.controlled-trials.com/ISRCTN74390617 Hypothesis "To test if wearing the R95 Particulate Respirator face mask, produced by 3M reduces levels of pollution exposure biomarkers in 40 healthy volunteers." Tests were done in Hanoi, Vietnam, from July to ...

No. The typical "pollution mask" I have seen are modified or styled after surgical masks. Surgical masks are NOT designed to filter intake air. They are designed to direct exhaust air away from a patient who is opened up and vulnerable to infection. The masks shown on your links appear to have possibly a sealing face mask, but the filters look clearly ...

that leaves the danger of the particulate matter which in my opinion, could be prevented with just a cloth wrapped around the nose and mouth. Diesel particulates are mostly in the 3-30 nanometre range of sizes. This is very fine and will not be stopped by normal cloth. 3M say a P2 (EU rating) filter should reduce exposure to diesel particulates. A P3 mask ...

I don't think I would make decisions based on masks available in the city markets of Bangalore. You need to decide what is reasonable for you. A cloth is not going to be as effective as a mask designed for particulate matter (and other pollutants). Cloth will only get large particles and nothing for other pollutants. But large particle is better than ...

Because anti-pollution masks contribute to overheating (that's my experience), they are an option in colder climates or during winter. Not only it is filtering the air, but is also warming it and your face. Get a double-filter one for less air resistance (theoretically half - parallel air restrictions act just like parallel resistors). Another point is that ...

Tainio et al, (Can air pollution negate the health benefits of cycling and walking?, Preventive Medicine, June 2016, Vol.87:233–236), produced a model for cycling (and walking) in polluted cities, using data of one particular type of pollution (fine particulate matter) from various global cities. Using a measure of minutes per day spent cycling, they find ...

There is some peer-reviewed evidence which shows that wearing a (proper) filtering facemask does have noticeable effects on one's vital signs compared to when not wearing a facemask. Whether this is enough to make a long-term difference in effects of city pollution on one's health, I can't say. Nevertheless, there are some cycling-specific masks which do ...
