Cabin pollen filter

So came across and watched this guy replace the pollen filter.

In fact the bottom of the housing slides out board, he yanked it off, could have broken the clips.
But i was surprised by the amount of leaves and debris that fell out.
At least the large leaves should have not got passed the grille just below windshield.
So i removed my cars pollen filter and the same, all leaves fell out. I vacuumed the filter and refitted.
So i had a mooch around.

So i discovered that the black plastic trim the air intake is moulded into is open ended left and right, can be seen when bonnet open.
It looks like when the bonnet closes rubber seals are supposed to touch the bonnet, but are about several millimetres short.
So if like my car you park near trees and i am too lazy to but the cover on, the area just below windshield collect leaves, twigs, seeds, etc.
They find their way to the corners and get sucked under the bonnet an then under the black trim.
It would appear there is no seal from the air intake to the grille.
So all the leaves get sucked in.

The seal A is too short, allowing leaves to be sucked under B.
Tomorrow i may look at fitting some mesh across the air intake or the ends where it is open ended B, might be easier.

Well found and interesting.

(That said, a pollen filter on a cabriolet? :? )

Some people prefer not to drive in a city during rush hour with the top down (or think of a dozen scenarios where you might want the roof up and not be breathing the ambient air...).
I guess with no pollen filter, you could run with recirc on, but the air gets a bit stale soon enough.

Yes, you're right.

Mind you, a pollen filter that doesn't work properly is nonsense anyway, isn't it?

Got some rubber door trim, might be able to extend the too short seal.

So i stripped out the black plastic trim, remembering the last time i removed it half the trim broke off where the clips attach.
So once off i could see the problem. The grille moulded into the top of the trim doesn't do much as air can enter from the corner of the bonnet.
The air intake is completely open to all sorts of debris entering.
So i found conveniently there were two clips holding some wires in place. I un-clipped those and place a fine mesh in front of the air intake, bent over at the top and then the clips back in place.
I just used a fine aluminium mesh, the sort used for patching up cars with epoxy resin paste.
I thought the grille on the top would have been connected to the air intake, but it isn't. Great design.
