"Air" full head protective mask
Would the Mayo Clinic recommend this new full face covering with heppa filters made by the company
MicroClimate. You can search Google for "Air MicroClimate mask"
Why or why not?
It's seems relatively affordable if it is a viable means of keeping yourself safe from Covid especially for high risk people.
Please let me know so I can decide if I should recommend to my grandma who just recovered from lung cancer.
