    In answer to Jeff on his thread, tried out the standard filter and itís just not worth it. Iím sure itíll stop the pollen but it also stops the air making an easier option simply to switch off the ac and fan and slowly roast instead.

    So Iíve looked at Option B as per belowÖÖ

    In looking for options I came across these - specifically designed to stop pollen for people who get a really bad reaction to it they are a fine mesh that still lets air through:

    I cut out an oversized piece and put it under the outer trim that goes round the HVAC intake. The trim clamps it down but the screws that hold the trim also went through the fabric so it’s going nowhere:

    If you look at the mesh it’s transparent but the gaps are pretty small, allegedly too small for pollen to go through:

    On switching on the fan airflow may be fractionally down but can’t really tell if it is. I’m sure this won’t stop all the pollutants a filter will but as I drive with the roof off when the pollen isn’t bad that hardly matters, just really want a solution for hay fever.

    All in all it should cut the pollen down, lets air through fine, is easy to fit and replace, can’t go anywhere so think there’s zero risk there and excusing the trimming on this one (very much a prototype) looks ok to my eye.

    (Edit: couple of the photos have uploaded sideways, can’t be bothered to faff with trying to spin them now, I’m sure it still shows what I wanted it to show)

    Indeed. And if we ever get a dry day I will !

    My guess is itíll cut down the pollen quite a bit - those screens are sold for medical reasons so if pollen went through them I think someone would notice that they donít work. Iíll wait for a hot dry day and go for a blat across the fens. Be interesting to see if Iím still fine hay fever wise afterwards and what gets picked up on the screen. If it does work I think itís a relatively neat solution though.
