Just replaced my cabin filter and I am not impressed with the oem filters, the material looks so porous that it will allow big particles and pollen through , waiting for fram and 3m to make a better aftermarket cabin air filter for the 2010's

^It's tough because anything more restrictive will reduce flow. The dinky fans in cars these days can't blow a fart off a blonde chick!
It's main function is just to stop leaves and such from getting to the AC coils, nothing more. No air quality benefits at all. Changing the filter is simply to allow your AC to work more efficiently.
If you make the filter more restrictive, the fan will not have to work as hard, but it won't move as much air. Weird concept but it's true.
What is more embarrassing is the terrible amount of blow-by past the OEM filters. They don't seal very well. I added some foam gasket to improve the seal. I wouldn't recommend doing that unless you know what you're doing though....

How can I tell if I have a cabin filter in my car?
I just bought it - it is an '06 hatchback.



Even if your car didn't come with one you can add it.

Funny this came up, I was told by Prima Mazda today while getting my oil change that on my next service I have to get it replaced. Any idea on what the price is?

The OEM filter is around $30+ but the service itself is expensive. I was charged $40 from a local popular mechanic for just the service and he mentioned its a lot of work to get to.
If your car didn't come with one, get one installed. Its worth it.
