samfreak 3rd Gear June 18, 2016 Share June 18, 2016 Normal will do. Or normal with carbon to help get rid of smell if your car does not already offer this feature in its AC. HEPA may result in high air flow restriction. HEPA is commonly referred to as those capable of filtering down to 2.5micron. But there is NO standard/official specification for automotive cabin air filter; unlike some others that may specific HEPA, ULPA etc. Generally, for cabin air filters, manufacturers just claim HEPA (2.5micron) if their cabin air filter has a relatively high filtration efficiency. My personal understanding is, if the filter can reach 80% efficiency at 1 micron, it may be advertised as PM2.5 function filter. Link to post Share on other sites More sharing options...
Darthrevan Supercharged June 18, 2016 Share June 18, 2016 I'm using activated charcoal filter..it works to a certain extent..filtering out most of diesel/petrol/foul smell before it enters the vehicle's cabin..the best is not to stop behind/beside a heavy vehicle or diesel vehicles as their exhaust fumes may still enter the cabin Link to post Share on other sites More sharing options...

aloha168888 Neutral Newbie October 16, 2016 Share October 16, 2016 In my opinion, HEPA is better. It will filter most of the particles. Link to post Share on other sites More sharing options...

Ysc3 Twincharged May 16, 2018 Share May 16, 2018 Aircon filter replace every 20k20k is almost 3 years for me... Link to post Share on other sites More sharing options...
Rustyz 5th Gear May 16, 2018 Share May 16, 2018 I notice newer car tend to circulate outside air in. thus the filter sure dirtier. I something let outside to circulate the cooling fin end up the filter very dusty and need replace. I only change when I smell moldy smell, I think charcoal is good enough no need HEPA, as need more energy to force air through the filter.. Link to post Share on other sites More sharing options...
flashbang Turbocharged May 16, 2018 Share May 16, 2018 how often should one replace the air-con filter ? how often should one replace the engine air filter ? do you base on time or mileage ? Timing is better. Imagine it has already filtered out some dirt and bacteria, now you let it sit in the filter for 3 years, that is very gross. I change mine every 6 months, aircon filters are cheap especially if it is easy to change. Most japanese/korean cars should be easy to DIY change.

Fcw75 Hypersonic December 27, 2018 Share December 27, 2018 Please change aircon filter often. This is only after 4 months and 5000km. Air quality is bad nowadays and I drive on normal roads only. 1 Link to post Share on other sites More sharing options...
Volvobrick Supersonic December 27, 2018 Share December 27, 2018 My charcoal filter when new also looked like the left side one.... You smoke big time in your car? How can it get so blacken (assuming on re-circulation mode most of the time)? Link to post Share on other sites More sharing options...

How can it get so blacken (assuming on re-circulation mode most of the time)? Never touch a cigarette my whole life...haha. No idea, air quality no good I guess. Yes always on re-circulation. The one on the left was white one actually, scary eh. Used to use charcoal aircon filter but realized the airflow slightly weaker and can’t even see if it’s clean or dirty...hahaha.
