have you check rubber seals on car doors?? That may be an issue, if rubber is off the place, not aligned or simply damaged..

I feel the carbon filters are working great in my car, u might try them. Price is double the normal one.

As the car ages, the flippers which control the air vents may not have closed completely even though the "re-circulated air control button" was activated.
These flippers are located behind the micro-filters housing.

A very simple solution is to seal-up the air vents with a sponge. See Naidu (behind Shell, Jalan Gasing) Cost less than RM 50. You will save the cost of changing micro-filters for life!

IC, but I got a stupid question, what happens over time when the sponge starts to break or brittle? Wouldn't it get suck in?

The sponge was quite hardy and I have been using it for more than 4 years now. The acid test was following closely behind a bus with "black smoke blowing hard and furious" and yet nothing permeates the cabin. Try it, after all it's really a cheap & fast solution!

[kayzhen911]

[hky]

Yeah I did that using those air con foam, no more outside smell, but downside is cannot recirculate air when someone fart. Haha

 

[zidee]

When someone or may you fart ...buka tingkap la ...unless your power window kong ...he he..

 

[hky]

but you have to admit that the re-circulate function is very effective compare to just open window.

May not be the air-cond. As the car ages, the flippers which control the air vents may not have closed completely even though the "re-circulated air control button" was activated. These flippers are located behind the micro-filters housing.
