A/C Musty Smells, Air filters & Drain Tubes

[tamrsoft]

I have the classic musty smell for about 5-10 mins after the A/C is switched off. I have replaced the pollen filter (in the passenger well) and have tried two different aerosoles ( a Comma product and one from Euro car parts), both have helped but not eliminated the problem. I have two questions in relation to this:

1) Is their an additional air filter in W210 model that I am not aware of.

2) I suspect a blocked drain tube not allowing the condensate to run away, anyone know of the location of this so that I can check that it is clear

There is probably one in the engine bay, at the bottom of the windscreen

I think this tube is in the dash area, directly underneath the heater core.
