Thereof, do free divers carry emergency air?

Freedivers do not inhale pressurized air, but the final breath we take before a dive still contains nitrogen from the atmosphere, which will still pressurize at depth. Nitrogen accumulation still happens, just very little compared to scuba divers.
Also Know, how long can you breathe on a spare air? A: It can last around 6-10 minutes depending on how fast you breath.
Furthermore, can you dive with compressed air?
Compressed air for scuba diving
To breath under water, scuba divers carry a air-tank with them filled with compressed air. For recreational diving this is normally normal atmospheric air, but compressed about 200 times to 200 bar (or 3000 psi). There is nothing special about the air.
Should you breathe out when freediving?
When you surface following your dive, the breathing you do is called 'recovery breathing'. It is important not to exhale any air until your mouth has cleared the surface, as exhaling on the way up deprives your body of oxygen and can make you more negatively buoyant.
