BMW 5 series ventilation problem?

[clematis]

I,ve recently bought a BMW 5 series (2000 reg 520iSE) and when I drive it
for any length of time, get a "dry throat" also the windows mist up. Been
told it could be a ventilation/air con problem perhaps. Appreciate any
advice as it,s putting me off an otherwise fine car

Thanks for your reply, I have now taken pollen filters out and will replace them soon and yes air is being recycled.
My wife thinks it could be Xmas tree air freshner that was in car!!
Clematis.

First of all, switch off the recycle and let the fresh air from outside the car to come in.
