Filtering while transferring to keg

I have a batch in the Fermentersarus (pressure kit) just about ready to keg. The problem I have is it is heavily dry hopped - pellets loose in the fermenter introduced via the collection bottle - and the unit is too big for my fridge so I cant cold crash. I wanted to rack the beer into the keg through the pressure kit and I'm afraid I will transfer some hop material. I have an 'in line' filter and a 20 micron filter cartridge. Any idea if this cartridge is too fine and will remove flavour/aroma?

I have only used this filter once with the cartridge it was supplied with (which I think is 1 micron) and it stripped most of the flavour from a cider so I put it in the back if the shed and haven't used it since.

Thanks Gash, I will run some Starsan through it and then blow it out with CO2 before I connect to the Fermentersarus and keg.
Cheers.
