Which Face Protection Do You Prefer A Mask Or A Plastic Screen or Both ?

I am using masks more than screens.

As Calgary has enacted a bylaw that masks MUST be worn in public, I find that sufficient.  I notice some workers in stores use a mask.  That likely makes sense, as they're apt to e in closer contact with many more people than I am during a day.   

I wear a navy divers helmet

i prefer to keep my face as far away from viral spew monkeys as possible.

if i have to enter a contamination zone i wear a cloth mask but would much prefer some serious protection.

hopefully there is someone working on a proper mask with filters,temperature control,UV lighting and maybe a small air tank for emergencies.

i want it to stop every viral particle,pollen grain and air pollution there is.
