pollon filter location on march 2000 1.8 with air con

hi all, just trying to find the pollon filter on my march 2000 1.8 freebie with aircon, looked under the glovebox and cant see where its located to, so popped off the flexi hose between the heater motor and the box to the left containing the internal aircon rad, put my hand inside but all i could feel was the aircon rad? where is the pollon filter too??? cant see any plates to unscrew etc... and looked on rave and shows a pollon filter (flat panel type) next to the flexi hose that joins to the heater motor but theres no slot on mine for it to fit. any help please, thanks

should be beneath left-hand side of facia, in the heater inlet system. should have to remove 3 screws and pull out the clips.
