Infinitely adjustable training mask with an air filter and a drinking device

A training mask comprising:

• an air impermeable mask body defining a mask interior space and perimeter seal, wherein said perimeter seal and said interior space are configured to enclose a wearer's nose and mouth;
• at least one adjustable inhalation resistance assembly extending through said mask body, said at least one adjustable inhalation resistance assembly comprising a first stationary internal component and a second external rotating dial parallelly and co-radially stacked on top of said first stationary internal component such that turning said second external rotating dial adjust sizes of corresponding overlapping inhalation adjustment apertures formed by said first stationary internal component and second external rotating dial to control inhalation resistance of ambient air through said overlapping inhalation adjustment apertures into said mask interior space in response to inhalation by the wearer;
• an air exhalation channel subassembly comprising:
• air permitting exhalation apertures located at a center of a top planar portion of said first stationary internal component;
• an air exhalation channel located at a center of a top planar portion of said second external rotating dial;
• and
• a flexible one-way check valve for regulating a discharge of exhaled air of the wearer;
• and
• an integrally-disposed replaceable particulate air filter incorporated into said first stationary internal component for filtering inhaled air that passes through said mask body;
• wherein the replaceable particulate air filter comprises a cylindrical mounting frame adapted to closely fit inside and extend through an internal chamber of said first stationary internal component and an air filter element adapted to be positioned in said cylindrical mounting frame and cover an entire area defined by an inner diameter and perimeter of the internal chamber of said first stationary internal component to ensure that only filtered clean air passes through said mask body during, inhalation by a wearer.
