Replacing pollen/Cabin filter on Nissan Micra K11 1999 Model

I was just wondering how you go about changing the pollen filter / cabin filter on a Nissan Micra 1999 model do you get to it from inside the car or under the bonnet. I have a Haynes repair manual but don't seem to be any mention in there about how to replace it.
Update: Additional Details: I havent got A/C on the micra its just normal does that mean we cdont have a filter on our Micra then?
