I don't mean to pry but how do you get on in your day to day life with such a condition? Do you wear a mask when outside?

I am honestly not trying to offend bit maybe that could be the answer when in a car.. just a thought

The way I see this is as follows. All cars use a similar air intake system via the plenum chamber ,where the wiper mechanism is located. Air is then is sucked into the Hvac system by the blower motor. A pollen filter is fitted either before or after the motor. Air is then distributed through the ducting system. This could be where your problem arises. The plastic ducting gives off a vapour when cooled and heated. notice the dirty film that collects on the inside of the windscreen. Have you tried any Mercedes models.? some are fitted with a charcoal type cabin filter that may help your problem.

This makes a lot of sense. Thank you. And of course when anything gets hot it's more prone to off-gas (to the tiny extent that may affect me) so I can hopefully mitigate effects by never running the heater at anything hotter than 'warm'.

I recently tried a Fiesta, which i really didn't want to buy as it was generally 'dodgy' and had an obviously fake service history, but I experienced no ill effects at all in that car! I wonder if different cars use different grades of plastic, some being more volatile than others?! I may try another Fiesta!

I will be getting a Mann Frecious carbon activated filter for whatever car i end up with.

Would there be any reason to think that replacing the plastic ducting you mentioned might help?

As moderator on behalf of the forum, Starman999, I do apologise for the needlessly offensive remark by 'andrew bairsto'. I have deleted his post and, as this isn't the first time that he has been offensive, also disabled his account.

I do hope the other posts have been helpful, and you have our sympathy.

My post regarding the Nissan Cube and also an in-car air purifier seems to have been removed too, not sure why?

Yes I don't know why your comment would have been deleted as it was entirely helpful and constructive. Still, I have a note of that air purifier and remember what you wrote about the Cube.

Starman - it was the post accusing you of beng a wind-up, which you rightly contradicted.

BBD's post is still visible to me and not hidden in any way, but here it is again in case anyone else can't find it.

"!Recently I was reading about the Nissan Cube, not the (3rd gen) versions sold officially in the UK, the 2nd generation (2002-2008) which would end up in the UK as a 'grey import'. Anyway, there was a built in 'ion clean air purifying system' available, probably as an optional extra. Not sure how to find out if one you looked at had this or not, but if you were interested, getting in touch with some of the numerous Japanese import specialists would be a good place to start.

"Also, and i think i may have mentioned this on a previous post of yours, unless someone else was posting with the same condition, but you can buy air purifiers to put in a car. I just Googled 'air purifier for car' and this is the top link, airbubbl.com/?gclid=CjwKCAiA2fjjBRAjEiwAuewS_f-WnR...E"
