Are there any filters on the ventilation system 230TE

[Brian23]

I have a 1992 230TE, no aircon. Are there any filters on the system and if so where?

If you mean pollen filters then it is possible.
From the early 90's we used to retrofit them,but in small numbers only.
If fitted,it'll be on the air intake,under the wiper motor.
