Abstract

A method for producing an improved mask or device for killing or deactivating pathogens, such as viruses. A mask or device produced in accordance with the method for producing. A method for killing, or making inviable, viruses, such as airborne viruses.

Claims (26)

1 . A method for producing a mask which deactivates a pathogenic aerosol, comprising the steps of:

(a) providing an outer face member having an inner surface and a structure defining at least one outer member opening;

(b) providing an inner face member having an outer surface and a structure defining at least one inner member opening;

(c) disposing a pathogen-deactivating assembly against the inner surface of the outer face member such as to generally cover the at least one outer member opening, said pathogen-deactivating assembly comprises a pathogen-deactivating matter;

(d) disposing the outer surface of the inner face member against the pathogen-deactivating assembly such as to generally cover the at least one inner member opening;

(e) forming an outer pathogen-deactivating pocket through the outer member opening; and

(f) forming an inner pathogen-deactivating pocket through the inner member opening.

2 . The method of claim 1 wherein said outer member opening and said inner member opening are generally co-axial.

3 . The method of claim 1 wherein said forming steps (e) and (f) comprises compressing the pathogen-deactivating assembly with the outer face member and the inner face member.

4 . The method of claim 3 wherein said forming steps (e) and (f) further comprises moving the outer face member and inner face member simultaneous with said compressing.

5 . The method of claim 1 wherein said outer pathogen-deactivating pocket and said inner pathogen-deactivating pocket comprises said pathogen-deactivating matter.

6 . The method of claim 1 wherein said pathogen-deactivating assembly comprises a fibrous material.

7 . The method of claim 6 where pathogen-deactivating matter comprises particulate matter.

8 . The method of claim 7 wherein said forming steps (e) and (f) comprises moving a portion of the particulate matter through said outer member opening and said inner member opening.

9 . The method of claim 8 wherein said forming steps (e) and (f) further comprises moving a portion of the fibrous material through said outer member opening and said inner member opening.

10 . The method of claim 7 wherein said particulate matter comprises particles having a total surface area ranging from about 20.00 m 2 /g to about 300.00 m 2 /g.

11 . The method of claim 7 wherein said particulate matter comprises a salt crystal including one or more of sodium, potassium, chloride, magnesium, sulfate, ammonium, phosphate, glutamate, tartrate, and their ions.

12 . The method of claim 5 additionally comprises passing

a first pathogenic aerosol through said outer pathogen-deactivating pocket and said inner pathogen-deactivating pocket to produce a second pathogenic aerosol having a portion of pathogens in said first pathogenic aerosol deactivated, leaving residual pathogens in said second pathogenic aerosol; and passing said second pathogenic aerosol containing said residual pathogens through said inner pathogen-deactivating pocket to deactivate at least a portion of said residual pathogens in said second pathogenic aerosol.

13 . The method of claim 12 wherein said second pathogenic aerosol is warmer than said first pathogenic aerosol.

14 . A mask produced in accordance with the method of claim 1 .

15 . A method for deactivating a pathogenic aerosol, comprising the steps of:

(a) providing a mask having an outer face member and an inner face member and a pathogen-deactivating assembly disposed between said outer face member and said inner face member, said mask further having at least one outer pathogen-deactivating pocket and at least one inner pathogen-deactivating pocket;

(b) passing a first pathogenic aerosol through said outer pathogen-deactivating pocket and said inner pathogen-deactivating pocket to produce a second pathogenic aerosol having a portion of pathogens in said first pathogenic aerosol deactivated, leaving residual pathogens in said second pathogenic aerosol; and

(c) passing said second pathogenic aerosol containing said residual pathogens through said inner pathogen-deactivating pocket to deactivate at least a portion of said residual pathogens in said second pathogenic aerosol.

16 . The method of claim 15 wherein said second pathogenic aerosol is warmer than said first pathogenic aerosol.
