Under glove box.
Plastic cover marked 'demontage' and 'remove' with an arrow.
Remove one screw on left side then slide cover to left, it should unclip.
Pull out tray with filter in.
I just took the 'filter' material out and left the mesh.
Then replace.
(Tip: take a couple of photos first to see where the bits are).
Helper.
