You could try sanding outside in a howling gale and leave off the mask, or
maybe clamp an electric fan to the work surface to suck the dust away.

For the ocassional sanding I do I use an el cheapo plastic nose mask with
a cloth border and a washable filtre. This rig probably keeps out some
sanding dust. It doesn't keep sanding dust from dimming the lenses on the
eyeglasses. The eyeglasses have to be pushed down the nose a bit to
accomodate the mask. I cant' wear the glasses for close up work anyway,
not having opted for bifocals yet.

I avoid sanding too deep by moving the sander quickly over the work so I
can see what's left underneath. When you work with a sanding disk on a
drill as I do you get used to using a light touch and being extra careful
how deep it goes.
