Abstract

Disclosed herein are methods and systems for face mask with replaceable filter cartridges and components. A face mask includes a mask component, a replaceable filter component, and a closure component. The replaceable filter component is bonded to and as between the closure component and the mask component when the closure component is attached to the mask component.

First claim

What is claimed is:

1. A face mask comprising:
a replaceable filter component including one or more vertical rib structures and a filter bonded along each of the one or more vertical rib structures in a serpentine formation via a molding process;
a closure component configured to receive the replaceable filter component for attachment with a mask component; and
a resilient seal interface, wherein the replaceable filter component is bonded to and in between the closure component, the resilient seal interface, and the mask component when the closure component is attached to the mask component,
wherein the replaceable filter component is bonded to the resilient seal interface, the closure component, and the mask component in between the closure component on one side and the resilient seal interface and mask component on an opposite side.

2. The face mask of claim 1 , wherein the replaceable filter component is a multi-folded filter.

3. The face mask of claim 1 , wherein the closure component is screwed onto the mask component.

4. The face mask of claim 1 , wherein the closure component is interference fit onto the mask component.

5. The face mask of claim 1 , wherein the closure component is press fit onto the mask component.

6. The face mask of claim 1 , wherein the closure component and the mask component comprise mating components.

7. The face mask of claim 1 , further comprising a rubber gasket configured to attach to the mask component, the rubber gasket configured to provide a seal against a user surface.

8. A face mask comprising:
a rubber gasket configured to attach to a mask component, the rubber gasket configured to provide a seal against a user surface; and
a replaceable filter cartridge component configured to attach to the mask component, the replaceable filter cartridge component comprising:
a filter frame including vertical ribs;
a filter configured to bond via a molding process to the filter frame in a serpentine shape along the vertical ribs, wherein the filter comprises a sidewall component and a base component, which are in mold labeled bonded to the filter frame during the molding process;
a closure configured for attachment with the mask component and to receive the filter frame; and
a resilient seal interface, wherein the filter frame is bonded to and in between the closure, the resilient seal interface, and the mask component when the closure is attached to the mask component,
wherein the filter frame is bonded to the resilient seal interface, the closure, and the mask component in between the closure on one side and the resilient seal interface and mask component on an opposite side.

9. The face mask of claim 8 , wherein the bond adheres the filter in the serpentine shape to the vertical ribs.

10. The face mask of claim 9 , wherein the filter is a multi-folded filter.

11. The face mask of claim 8 , wherein the replaceable filter cartridge component is screwed onto the mask component.

12. The face mask of claim 8 , wherein the replaceable filter cartridge component is interference fit onto the mask component.

13. The face mask of claim 8 , wherein the replaceable filter cartridge component is press fit onto the mask component.

14. The face mask of claim 8 , wherein the filter frame is attached to the closure.

15. The face mask of claim 14 , wherein the filter frame is interference fit onto the closure.
