sanding mask?

[brandonA.]

Hello I have been sanding 2K urethane high build primer and wearing a 3m dust mask. (The plain ones all white in color with no vents) However at the end of the day I see dust when I blow my nose so I know it is not stopping the dust. Is there a better dust mask to use? One with a breathing valve? I don't want to use my 3m painting mask with the 2 filters on it that seems like overkill. I'd like to be safe so any ideas on a better mask? I don't want to wet sand this stuff either...

Thanks....
