Something horrible & terrible happened to my new Nissan Almera (which I bought in 2016 but still at very low mileage as I only drive quite a short distant during weekdays).

On 23 December 2016 (Friday), something horrible happened, after leaving my Almera at home for 6 days (without driving), and as usual, I started my car engine & switched on the air conditioner & all of the sudden the air-cond blew out a large amount of “snow-like sticky white films” (which I never seen before !), the amount of this “white films” was so huge that it stuck all over my body, my face, nose, mouth & the entire car interior... As a result of that I was coughing non-stop but I immediately drove my car to the nearest Nissan service centre in Chan Sow Lin KL for inspection... & the supervisor there told me that he has seen a few cases like this before, where car owners left their cars idle (without driving) for 3-4 days & then when they started the engine the air-cond blew out sticky white film (similar to my case). I was terrified because the entire car interior & my whole body were covered with this “snow-like sticky white films” but the supervisor told me it was just “normal dust” - which I don’t believe because as a car driver for more than 20 years I had never seen anything like this (sticky white film), or heard anything like this before. For sure it was definitely not the kind of "normal dust" we see every day !

Since the air conditioner works on close-loop environment & in order to get rid of the entire mess, I have vacuumed the car interior a few times... also, my family have to wear face mask (when using the car) because all of them have serious sinus problem (and regularly taking sinus medication), but still, after a while of driving, this “white films” will appear again.. although with smaller size & lesser quantity now, still, it can be seen all over the car interior… and since I have coughing almost every day now, I have to stop driving the car for the time being because I just can’t keep vacuuming the car everyday…

I have taken a few photos (of those white films) & in fact, my Almera has just undergone the 2nd scheduled service (i.e. 10,000km) about a week earlier...

Can anyone kindly enlighten:

1. How could that happen ?
2. What are those snow-like sticky white films (that emitting out of the air conditioner) ?
3. Are they dangerous compound & hazardous to human ?

Attached are photos that I taken on 23 December 2016..

The air cond seems to be OK, I think, but I am not 100% sure... I think I need to observe the air cond's coldness more thoroughly now..

You could be right... the freon of the air-cond system could probably leaked... evaporised & sucked by the air-cond pump into the car interior (and becomes the snow-like "white sticky film"), that is possible... but still, I think the air-cond itself has its own air-filter (i.e. cabin filter) that filterise dusts, dirts or any solid particles... before it enters the car interior..

No, I did not open the Ventilation (i.e. the On/Off ventilation-switch which is meant for taking the fresh-air from atmosphere outside into the car)

Actually, the Nissan's supervisor (at Nissan service centre - Chan Sow Lin) had double-checked my Ventilation-Switch that you mentioned earlier... & he confirmed that it was not the cause because my ventilation button was always in "switched-off" position..

The supervisor had actually witnessed the whole incident (of this sticky white film mess)... It was horrible.. but he told me he has seen a few cases like this before.. where car owners left their cars idle at home (without driving) for 3-4 days & when they started their cars later they faced the same problem (similar to my case)... but I am not sure if he was referring to all Nissan cars.. or just Nissan Almera..

No, I don't have "cabin filter" in my car..

Thank you for your suggestion..
Now I know that "cabin filter" is the air filter that filterise dusts, dirts, or any solid particles (of air conditioner's incoming cold air) before it entering the car interior.. & personally I think, Nissan Almera should have cabin filter installed for every new car.. anyway, I need to check first..
