Good thing we're all wearing face-masks to avoid cold, flu, and COVID-19, right?

Thise face masks are useless against anything that doesn't directly spray in your face.

When I breath in face mask clings tighter to my face, meaning the air gets filtered, meaning that unless this dust is smaller than viruses, they'd help.

Of course depends on what face masks you'd be using. Surgical are of not much help, but other than that efficiacy has been studied and confirmed very high in that last pandemic, which spread mostly by airborne particle, not droplets (so contrary to your claim they protect).

You can literally taste the difference between wearing a mask on the Tube and not.

Surgical masks aren’t. But N95/KF94 were originally designed for exactly this sort of use case.

Could you post a link to some sort of study or substantive reason you think this?
