Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
you can duct tape a/c fliters on any intake of any of the fans you use, reduce the amount of dust that can spread and in turn filter your room's air
My only input is I do not run my dehumidifier, when I have freshly coated screens, in the racks the fan in the dehumidifier stirs up dust, dust = pin holes.
