I'm using my bicycle to ride from home to work and back. Now I face a problem that the air is not so clean: dust, car exhaust etc.
So I'm thinking of buying a respirator (i.e., an anti-pollution mask) to filter the air I breathe.
But before I buy it I need advice on what should I consider when first choosing one?
I've got a respro bandit now and it seems to be what I needed. It really does it's job filtering the air well and doesn't make it too hard to breathe.
