ive no idea when mines was last changed, and ive no idea where its located till i get home and get the chance to look at the manual, but i wonder who else is in the same boat as me to when theres was last changed 
used to get steamed up windows in the RX8 untill i changed the pollen filter, then all was okcarts said:we done a bit on this a couple of years back, it's easy to change its behind the glove box there's two filters... and if you dont know when it was last changed do it... I bet you notice a difference in the air flow...
