Can you recommend some European cities good for someone with asthma?

Essentially a European city with more or less clean air and not too much pollen.

1. Switzerland? I guess I don't really know how much pollen they have going on. But I imagine their air is pretty clear! Maybe some of the mediterrainian cities, south france, italy, greece. Usually the beach has enough air coming through to clean out any smog and very little pollen.
2. most european cities have cleaner air than the american cities, how many pollen there are, depends on the time of the year you get there... i would suggest some city in switzerland like bern or lucerne.... hope you´ll have fun;-) ps: dont travel to rome, the air there is horrible i´ve been there once for a week and couldn´t stop coughing even though i don´t have asthma (only hypersensitivity of lungs)
