Maybe they don't breathe through their noses.

The isolation masks we have here (99% EFF at .1 Microns) can be shaped around the bridge of your nose and they provide a good fit.

The N95 masks we use at work (3M) also come with an adjustable noseclip. I've seen the same model available in hardware stores and it works well for what it does. If adjusted properly the seal is pretty tight. The fit should be identical to your N99 masks, though of course the N95 standard offers somewhat inferior protection.
