demystify windscreen?

[alexsh1]

I have noticed that my windscreen is more often getting fogged.
Any reason for that? Shall I change the air filter?
Also is there any spray or windscreen cleaner so that its not getting mysted
that often.

Thanks

Common across the E46. Clean the windows thoroughly on a regular basis and try some RainX Anti fog on the inside.

it's been quite humid recently thats why, but as purvesh said a very common issues on E46, even more so on M3s.

Just keep the AC on and all is good :)

Thanks guys,
Will try to clean it, apply RainX and see how it goes

you might want to try popping down to your local sports gear shop and buy some anti-fog spray that people spray into their swimming goggles/masks to prevent build up of mist/fogs. they work better than anything else in my experience.

Teddy, thanks very much
Will pop in at local Decathlon to see what they have :)

BTW, what are the simptoms to change the saloon air filter?
