Same with these masks, keeps away some dust that is about it.
Pollution on the road tends to follow a gaussian distribution. This means that the pollution levels fall away exponentially from the center of the road. Most of our cycling is done on the side of the road so we are in lower areas of polution. If you are driving on the otherhand your air intake is close to the car infront and hence sucks alot of polution and that is why you experience more pollution in a car than out of it.
People who don't ride because of pollution are just looking for an excuse and if it was not pollution it would be something else. It's a free choice.
