it is most likely from the aircon system, you can have them cleaned out by specialists.

don't think so, some even say you can do it yourself with a kit but I haven't looked, it's just a antibacterial flush of the heater/chiller matrix and associated parts.

Assuming it is the aircon then don't bother with the deodoriser kits from Halfords and the like. They make the car smell nice for a while but don't deal with the cause of the problem.
A good aircon specialist will charge around £70 to clean the system and check it over and regas it.

At the same time you will want to replace the pollen filter (use search on this forum and you will see how easy that job is).

A sulphurous small can come from a 'smelly cat' (catalyser) but is really only noticeable outside the car or when stationery/ reversing with the windows open.

The cat on my old Volvo absolutely stank and there was nothing that I could do about it save to explain that I was not living on a 'vindaloo exclusive' diet

No problem, if you give your location I might have a link to a local aircon specialist.

No worries, you may be able to help someone else in the future; "what goes around, comes around".

I have a similar situation but it only starts to smell if I allow air from outside & AC is off. Can it be just the filter?

More likely a combo of dirty filter and a bit of bacteria growing.
Change the filter and run the system, with AC on, 'cycling' through the settings 'head, demist, feet etc. on maximum temperature (not today obviously unless you like saunas). Should kill off some of the more delicate ones and a new filter can only help.
