The life support system on the International Space Station cleans air and adds oxygen to maintain fresh air.
Carbon dioxide is captured by scrubbers using using a base, such as lithium hydroxide. Methane, ammonia, acetone, and other gaseous human byproducts are removed with activated charcoal filters.
Oxygen is created from water by electrolysis, which divides water into oxygen for the station and hydrogen, which is released into space. Oxygen tanks provide a backup supply of oxygen.

they dont exactly "generate" fresh air, there are deliveries of supplies ect to the space station very frequently, if oxygen isn't brought in these deliveries, then they have a filter, you can use them under water. they take the co2 that you exhale, put it through a filter and the filter breaks up the molecule and basically "throws away" the carbon

There are 3 sources of oxygen - they have "oxygen turbines", very very like those on commercial airplane emergency structures. in addition they use 'scrubbers', which cleans the CO2 from the air, and that they have got oxygen tanks that are replaced hardly.
