1. An apparatus, comprising:
a mouth aperture configured to be disposed in fluid communication with a mouth of a user;
a nasal aperture configured to be disposed in fluid communication with one or both nostrils of the user when the mouth aperture is disposed in fluid communication with the mouth of the user;
a nasal fluid reservoir configured to be in fluidic communication with the one or both nostrils;
an oral fluid reservoir configured to be in fluidic communication with the mouth of the user;
a septum disposed between the nasal fluid reservoir and the oral fluid reservoir;
a septal inhalation valve disposed within the septum and configured to transition between a septal inhalation valve open configuration in which the nasal fluid reservoir is in fluidic communication with the oral fluid reservoir, and a septal inhalation valve closed configuration in which fluidic communication between the nasal fluid reservoir and the oral fluid reservoir is substantially prevented, the septal inhalation valve being configured to assume the septal inhalation valve open configuration in response to oral inhalation or nasal exhalation by the user, and the septal inhalation valve closed configuration in response to oral exhalation or nasal inhalation by the user;
a first nasal inhalation valve disposed between the nasal fluid reservoir and a first inhalation channel that is in fluidic communication with a first inhalation inlet, and configured to transition between a first nasal inhalation valve open configuration in which the nasal fluid reservoir is in fluidic communication with the first inhalation channel, and a first nasal inhalation valve closed configuration in which fluidic communication between the nasal fluid reservoir and the first inhalation channel is substantially prevented, the first inhalation inlet being configured to be disposed above the user's shoulders when the mouth aperture is disposed in fluid communication with the mouth of the user and the nasal aperture is disposed in fluid communication with the one or both nostrils;
a second nasal inhalation valve disposed between the nasal fluid reservoir and a second inhalation channel that is in fluidic communication with a second inhalation inlet, and configured to transition between a second nasal inhalation valve open configuration in which the nasal fluid reservoir is in fluidic communication with the second inhalation channel, and a second nasal inhalation valve closed configuration in which fluidic communication between the nasal fluid reservoir and the second inhalation channel is substantially prevented, the second inhalation inlet being configured to be disposed above the user's shoulders when the mouth aperture is disposed in fluid communication with the mouth of the user and the nasal aperture is disposed in fluid communication with the one or both nostrils;
a first oral exhalation valve disposed between the oral fluid reservoir and a first exhalation channel that is in fluidic communication with a first exhalation outlet, and configured to transition between a first oral exhalation valve open configuration in which the oral fluid reservoir is in fluidic communication with the first exhalation channel, and a first oral exhalation valve closed configuration in which fluidic communication between the oral fluid reservoir and the first exhalation channel is substantially prevented, the first exhalation outlet being configured to be disposed above the user's shoulders when the mouth aperture is disposed in fluid communication with the mouth of the user and the nasal aperture is disposed in fluid communication with the one or both nostrils;
a second oral exhalation valve disposed between the oral fluid reservoir and a second exhalation channel that is in fluidic communication with a second exhalation outlet, and configured to transition between a second oral exhalation valve open configuration in which the oral fluid reservoir is in fluidic communication with the second exhalation channel, and a second oral exhalation valve closed configuration in which fluidic communication between the oral fluid reservoir and the second exhalation channel is substantially prevented, the second exhalation outlet being configured to be disposed above the user's shoulders when the mouth aperture is disposed in fluid communication with the mouth of the user and the nasal aperture is disposed in fluid communication with the one or both nostrils;
a first inhalation filter disposed upstream the first nasal inhalation valve to filter ambient air drawn into the first inhalation inlet from an ambient environment;
a second inhalation filter disposed upstream the second nasal inhalation valve to filter ambient air drawn into the second inhalation inlet from the ambient environment;
a first exhalation filter disposed downstream the first oral exhalation valve to filter air exhaled by the user for discharge to the ambient environment;
a second exhalation filter disposed downstream the second oral exhalation valve to filter air exhaled by the user for discharge to the ambient environment;
a first filter block housing containing the first inhalation filter and the first exhalation filter; and
a second filter block housing containing the second inhalation filter and the second exhalation filter,
the first inhalation channel, the second inhalation channel, the first exhalation channel, and the second exhalation channel each being defined within respective housings distinct from one another;
the first and second nasal inhalation valves being configured to assume the first and second nasal inhalation valve open configurations, respectively, in response to nasal inhalation by the user, and the first and second nasal inhalation valve closed configurations, respectively, in response to nasal exhalation by the user,
the first and second oral exhalation valves being configured to assume the first and second oral exhalation valve open configurations, respectively, in response to oral exhalation by the user, and the first and second oral exhalation valve closed configurations, respectively, in response to oral inhalation by the user.
