Doctor Demonstrates Effectiveness Of Face Covering

 Various Coverings Demonstrated

Using a vaping pen this doctor graphically demonstrates how ineffective a wide variety of face coverings are at stopping a vapour that is actually larger than the covid virus.

Using surgical masks, multi layer high end masks, masks with replaceable cartridges and even home made cloth masks this doctor clearly demonstrates how aerosol passes around and through masks.

The one with a replacement cartridge (like you would see in a paint booth) will stop a virus from coming 'in' but will not protect from it being expelled on the exhale.

Very clear demonstration.
