Easy to change follow this to step 3 - when at step three you'll have the pollen filter in front of you (held in by one screw or none if the last person was lazy)!
Exploded photo at stage three and you'll see his pollen filter partially removed

The filter is the bit above the plastic with two hooks - this bit plastic slides off the hook supports and the filter can be removed.
TPS is worth checking for a price.
