"Pollen filters" are fitted in car heating systems. 2 questions:-

1 Do they actually do what they say, catch the pollen?

2) Can you brush/shake/back-blow such a filter to get the pollen out
*still alive* and able to fertilise?

When I used to hoover out the one on my previous car to get rid of the
larger bits of leaf etc the filter got increasingly dirty until replaced,
hoovering it didn't seem to clean it in any way, the "dirt" appeared
trapped. Same on our electrostatic filter on our warm air central heating,
you just have to replace the filter pads with new.

They will catch some of it and brake dust and other particulates.

Doubtful - the forced airflow will rapidly dessicate the pollen on the
filter and it loses viability after a few hours or days. The pollen
would have to be married with the right plant flower to work and that in
the UK would likely be a grass or a conifer with wind borne pollen.

It might be easier in Japan where vast amounts of cryptomeria pollen
accumulates inches deep on the pavement in spring.

1. Possibly
2. how would you know what pollen you had? It could be anything and
everything.

Under a microscope you can tell them apart; there are photos on the
web to help you with this. Pollen caught by filtration WILL be
anything, but pollen will only fertilise the same species.

Good luck with identifying pollen, it all looks the same to to me.
