Why not just wear one of those mask things that I have seen cyclists wearing in big cities.
Right you are then. Having not cycled, or lived, in big cities I had no idea. I've just seen folks wearing the things.Because they're entirely ineffective.
Not as a placebo solution to a relatively low risk problem that could enable him to carry on riding they aren't.
Kingston to Chiswick looks a pretty OK commute, through Richmond park, choice of 2 bridges to cross the Thames. Quite a few back-roads less frequented by trucks and buses.The Main problem is crossing the river and getting into Chiswick
The latest advise to pedestrians is to walk as far away from the road as possible. I have been filtering between two rows of stationary traffic.
I don't think so

When you were a kid the wheel was still in the realms of science fiction...Personal Jetpack (I was promised we'd all be using these when I was a kid).
And they must be a bit more effective than walking a couple of metres away in the same air.
From what I understand (which may not be up to date information, I admit), none of the main brands of masks aimed at cyclists (eg Respro, Totobobo) are able to filter out ultra-fine particles, which are the most harmful ones.
The filter will probably go grey after an hour's use in central London but that only means it has caught the larger particles.
What's more, they tend to make breathing very difficult if you're putting in anything above the bare minimum level of effort - so probably fine for walking, but not really for cycling.
The correct ones are available, they'll filter out the particles. You have around 30 - 45 minutes of use from them.From what I understand (which may not be up to date information, I admit), none of the main brands of masks aimed at cyclists (eg Respro, Totobobo) are able to filter out ultra-fine particles, which are the most harmful ones.

The more rain and wind you get on a day the cleaner the air will be.
