The interactions between the components of the ISS Environmental Control and Life Support System (ECLSS)

The International Space Station (ISS) Environmental Control and Life Support System (ECLSS) is a life support system that provides or controls atmospheric pressure, fire detection and suppression, oxygen levels, proper ventilation, waste management and water supply. It was jointly designed and tested by NASA's Marshall Space Flight Center, UTC Aerospace Systems, Boeing, Lockheed Martin, and Honeywell, inc.[1]

The system has three primary functions: Water Recovery, Air Revitalization, and Oxygen Generation, the purpose of which is to ensure safe and comfortable environments for personnel aboard the ISS. The system also serves as a potential proof of concept for more advanced systems building off of the ECLSS for use in deep space missions.[1]
