HELP! Material or screening to stop pollen.

Greetings!

Long time reader, first time writer.
I am an intermediate level grower with a problem.
My outdoor plants have been getting pollinated from an unknown source so I am trying to design a small greenhouse.
I live in Canada so I can grow without issue.
I think a small greenhouse would just be too hot for the plants but I am not sure how to ventilate it without pollen getting in.
I would like to put small windows in the greenhouse with some kind of screening or material that lets air through but not pollen.
Anyone with any ideas or knowledge of a material to use, please let me know.

Thanks all.

You might consider replacing a panel in a window or tent with a hepa filter or even just a good a/c filter which might be more readily available in a wide range of sizes
 
If you could draw your air in through a dustop furnace filter should be good. They make them for people with allergies should stop all pollen.
 
They make a/c filters with a rating called MERV.... the higher the number like 11,12,13 etc....the finer particulate filtration it will provide ...too high a number and you’ll need a greater size fan to pull air thru
