How to replace the cabin air filter in Audi A2?

I recently bought an Audi A2 and I noticed that the air coming out of the vents does not smell fresh. I'm guessing it's time to replace the cabin air filter, but I've never done it before. Any tips or instructions on how to do it properly?

Replacing the cabin air filter in an Audi A2 is actually quite easy. First, you need to locate the filter, which is usually behind the glove box. Then, you just need to remove the old filter and replace it with a new one. Don't forget to properly dispose of the old filter. -Peter
