Systems, apparatuses, and methods for improving powered air purifying respirator

An air-purifying respirator comprising:

• a coolant container comprising a coolant material stored within a container shell, wherein the coolant container defines a central hole;
• a refrigerant evaporator comprising a refrigerant material configured to reduce a temperature of the coolant material;
• and
• a breathing tube comprising:
• a cooling portion located within the coolant container;
• a breathing tube inlet opening connected to an air-purifying device outlet opening;
• and
• a breathing tube outlet opening connected to a respiratory headgear inlet opening to provide purified air thereto,
• wherein the breathing tube enters the coolant container through a coolant container entrance opening of the coolant container and exits the coolant container through a coolant container exit opening of the coolant container,
• wherein at least a portion of the refrigerant evaporator is positioned within the central hole of the coolant container such that the refrigerant evaporator is secured through a male-female interlock mechanism, and
• wherein the cooling portion of the breathing tube is in contact with the coolant material in the coolant container and at least partially surrounds the central hole such that both the coolant container and the refrigerant evaporator are configured to absorb heat from purified air in the breathing tube.
