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.

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

In my opinion, HEPA is better. It will filter most of the particles.

 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.. 


If anyone can have it, I don't want it.

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.
