Social Snorkel

The coronavirus (especially if attached to a water(/sputum) droplet), has a still-air diffusion speed of your average brick, relying on air currents to spread : 5-6 feet up from the spewing orifices and the air is relatively clear, so...
  [vote for,

a length-adjustable (think automobile antenna), lightweight, bifurcate-tube/filter/mask combination with robust head-straps.

The snorkel/filter assemblies attach to the mask via a standard NATO connection, enabling optional adaptation to existing NBCW fashionwear ; adapters for older/foreign model gasmasks available on request.

(and thankyou Jutta, for the new category)

       Can there be a rigid carbon-fibre version ?   

       Er, how low are the overhead power lines in your part of the planet ... ? <Sniggering/>

       I seriously considered picking up a mil. gas-mask, but cartridges are difficult to find and (IIRC) only rated for a few hours (and no clue how to rejuvenate them).   

       Side-topically, I've considered going clean-shaven to make the piddly masks I do have more effective, but even unseen razor-burn would provide more attachment points.

       // no clue how to rejuvenate them //   

       Can't be done- single use, and discard. Once unsealed, they degrade anyway irrespective of use, so one that's been opened and put aside is junk after a couple of days.   

       Consumer-grade non-sealing (medical type) masks are more a gesture of intent than practical protection. They'll reduce droplets and particulates, but not stop them, and besides they leave the conjunctiva completely exposed.   

       Bizarrely, your aquatic mask-and-snorkel suggestion works (mechanically) quite well. But since the majority of users blithely ignore the necessity for post-exposure decontamination protocols, it's all a complete waste of time.

       The snorkel should be a flexible hose held up by a drone. Then with the air intake over 6 feet above the crowds no filter is necessary.

       Intake high up; exhaust (unfiltered) at head height ...   

       Of course, if you're infected, the unfiltered output is going to contaminate all those around you ...

       That's their problem.

       It would be an interesting study to correlate height demographics with infection rates and immune system loads and conditioning. Is this another evolutionary advantage of being tall?

       That's entirely possible. Droplets will be drawn downwards by gravity... the infective miasma will swirl around somewhere below average mouth height.
