On my older 9000, after I pulled the air filter (not a pollen filter like yours, less sophisticated) I could see the fins and coils of the unit. I used a spray liquid product call a "coil cleaner" which I purchased at an industrial hardware store. Don't know how these products are distributed in UK. This was not something I could buy in a neighborhood store. Cost abut $10 USD. Did the trick, left behind a slight lemony smell, which was nice. The pollen filter may be in a box-type arrangement and you may have to remove other panels to get to the coils. Good Luck
