Protective face mask

Abstract

A protective face mask may comprise an outer housing including a plurality of ventilation holes, and an inner housing detachably coupled to the outer housing, the inner housing configured to cover a nose and a mouth of a user, the inner housing including a second plurality of ventilation holes. The protective face mask may also include a replaceable filter configured to be received in a space between the inner housing and the outer housing. In some embodiments, the protective face mask includes a dual chamber breathing design configured to reduce moisture collection within the mask.

1 . A protective face mask, comprising:
 an outer housing including a first plurality of ventilation holes, wherein the first plurality of ventilation holes allow for air ingress and egress;   a replaceable filter removably coupled to the outer housing, wherein the replaceable filter is configured to substantially cover each hole of the first plurality of ventilation holes;   an inner housing detachably coupled to the outer housing, the inner housing configured to cover a nose and a mouth of a user, the inner housing including a second plurality of ventilation holes defining a first portion and a second portion, and a solid dividing line that extends between the first portion and the second portion, wherein the solid dividing line defines an upper chamber including the first portion of the second plurality of ventilation holes and a lower chamber including the second portion of the second plurality of ventilation holes, wherein the replaceable filter is removably coupled between the outer housing and the inner housing, and wherein each of the first portion of the second plurality of ventilation holes and the second portion of the second plurality of ventilation holes allow for air ingress and egress; and   an overmold removably coupled to the inner housing, whereby the replaceable filter and the inner housing are located between the outer housing and the overmold, the overmold including a partition extending between the first portion of the second plurality of ventilation holes and the second portion of the second plurality of ventilation holes, wherein when the protective face mask is worn by a user, the partition physically contacts the user between the nose and the mouth and extends substantially an entire width of the inner housing of the protective face mask.
