Hi could anyone tell me where the air filter is on my opel (vauxhall) astra 2001? I know there is one under the dashboard, i had it changet, but pieces of dust and durt kept entering the cockpit. I took it back, they changed it ok, and said that now it ok, there is no gap between the support and the filter. Still, after one week I have the same problem. Maybe there are two filters ? What could be the problem? When I turn on the wents (2-4 speed) it throws all sorts of stuff directly in my face 
It`s annoying. Pls help.
