Hey what's up guyz, im kinda confused on how this filter works, does it filter out the stuff thats coming into the car, or does it filter stuff thats already in the car? OR does it do both?

Thankz in advance...

Later..

 

From everything I have learned it does both. It filters incoming outside air as well as recirculated air.

 

Nice shiny car.

Are you talking about the in-cabin micro filter? The best money-making scheme next to rust-proofing and clear coat protection that Nissan has come up with to date?

 

you'd think they'd get it right by now. It's 2002 for god's sake. I'm talking about that nasty, musty smell from the vents after you use the air conditioner. It's condensation from inside the system that gets all nasty after a while.

I had an old dodge van that didn't have that problem - they need to fire the dude that engineered the a/c.
