Abstract

A filtration mask protects the wearer against airborne hazards. The mask is reusable and may be used in a number of configurations. The mask includes filters located to the side and beneath the line of sight of the wearer. The filters may be tailored to the use and type of environmental hazard.

First claim

What is claimed is:

1. A configurable face mask, comprising:
a mask body formed of a substantially nonporous material, the mask body comprising a locking male threaded attachment having locking threads that traverse an exterior surface of an entire length of the locking male threaded attachment;
at least one side housing located on one side of the mask body, the at least one side housing comprising:
a securing threaded device, wherein the securing threaded device is adapted to engage the locking male threaded attachment of the mask body; and,
an air-filtering device secured to the mask body by the securing threaded device;

a strap attachment having a pivoting ring fitted around the locking male threaded attachment of the mask body, wherein the strap attachment is adapted to swivel in relation to the locking male threaded attachment, the securing threaded device adapted to tighten the pivoting ring against the mask body in a locked position; and,
a valve coupled to the mask body at a location separate from the at least one side housing, wherein the valve permits at least one of an exhalation and inhalation to pass through the face mask.

2. The configurable face mask of claim 1 , wherein the air-filtering device comprises a filter housing having a filter.

3. The configurable face mask of claim 2 , wherein the filter comprises a fibrous filter.

4. The configurable face mask of claim 3 , wherein the fibrous filter comprises non-woven polypropylene material.

5. The configurable face mask of claim 3 , wherein the fibrous filter comprises a coffee filter paper.

6. The configurable face mask of claim 2 , wherein the filter comprises activated charcoal.

7. The configurable face mask of claim 2 , wherein the filter comprises an electrostatic material.

8. The configurable face mask of claim 1 , wherein the air-filtering device comprises a cap, wherein the cap is adapted to seal the air-filtering device.

9. The configurable face mask of claim 1 , wherein the substantially nonporous material comprises a resin.

10. The configurable face mask of claim 1 , wherein the substantially nonporous material comprises a nylon.

11. The configurable face mask of claim 1 , wherein the at least one side housing comprises a first and a second side housings, wherein the first and second side housings are located on opposite sides of a longitudinal centerline of the mask body.

12. The configurable face mask of claim 1 , wherein the strap attachment is configured to accept a plurality of strap types.

13. The configurable face mask of claim 12 , wherein the strap attachment further comprises a mechanism for selecting a position of the strap attachment from a plurality of strap attachment positions.

14. The configurable face mask of claim 1 , wherein the at least one side housing further includes a valve.

15. The configurable face mask of claim 1 , wherein:
the at least one side housing further includes a first check valve, wherein the first check valve permits the inhalation; and
the valve coupled to the mask body comprises a second check valve, wherein the second check valve permits the exhalation.

16. The configurable face mask of claim 15 , wherein the air-filtering device comprises a filter.

17. The configurable face mask of claim 1 , further comprising:
a face seal coupled to a rear portion of the mask body.

18. The configurable face mask of claim 17 , wherein the face seal comprises silicon.

19. The configurable face mask of claim 1 , further comprising:
an information label located on the mask body.

20. The configurable face mask of claim 1 , wherein the face mask is manufactured using additive manufacturing technology.

21. The configurable face mask of claim 1 , wherein the nonporous material further comprises a color definable by a red, a blue, and a green color value.

22. The configurable face mask of claim 1 , wherein the nonporous material further comprises a color expressible by a hexadecimal value.

23. The configurable face mask of claim 1 , wherein the face mask is manufactured using injection molding.

24. The configurable face mask of claim 1 , further comprising:
a cover securable over the valve.

25. A configurable face mask, comprising:
a mask body formed of a substantially nonporous material, the mask body comprising a first locking male threaded attachment having locking threads that traverse an exterior surface of an entire length of the first locking male threaded attachment;
a first housing located on a first side of the mask body, the first housing comprising:
a first securing threaded device, wherein the first securing threaded device is adapted to engage the first locking male threaded attachment of the mask body;
a first air-filtering device secured to the mask body by the first securing threaded device; and,
a first strap attachment having a first pivoting ring fitted around the first locking male attachment of the mask body, wherein the first strap attachment is adapted to swivel in relation to the locking male threaded attachment, the first securing threaded device adapted to tighten the first pivoting ring against the mask body;

a second housing located on a second side of the mask body, the second housing comprising:
a second securing device, wherein the second securing device is adapted to engage a second locking male attachment of the mask body;
a second air-filtering device secured to the mask body by the second securing device, wherein at least one of the first air-filtering device and the second air-filtering device further comprises a filter; and,
a second strap attachment having a second pivoting ring fitted around the second locking male attachment of the mask body, wherein the second strap attachment is adapted to swivel in relation to the second locking male attachment, the second securing device adapted to tighten the second pivoting ring against the mask body.

26. The configurable face mask of claim 25 , wherein at least of one of the first air-filtering device and second air-filtering device further comprises a cap, wherein the cap is adapted to seal the air-filtering device.

27. The configurable face mask of claim 25 , wherein the filter comprises a fibrous filter.

28. The configurable face mask of claim 27 , wherein the fibrous filter comprises non-woven polypropylene material.

29. The configurable face mask of claim 27 , wherein the fibrous filter comprises a coffee filter paper.

30. The configurable face mask of claim 25 , wherein the filter comprises activated charcoal.

31. The configurable face mask of claim 25 , wherein the filter comprises an electrostatic material.

32. The configurable face mask of claim 25 , wherein the strap attachment is configured to accept a plurality of strap types.

33. The configurable face mask of claim 25 , wherein the second securing device comprises a quick-click cam lock.

34. The configurable face mask of claim 25 , wherein the substantially nonporous material comprises a resin.

35. The configurable face mask of claim 25 , wherein the substantially nonporous material comprises a nylon.

36. The configurable face mask of claim 25 , further comprising:
a face seal coupled to a rear portion of the mask body.
