You can see in the description that this is an oxygen concentrator—it pulls oxygen from the room air. It’s the same type of device Ruby discusses in the post. I assume they call it a “generator” in the headline because people don’t know what a “concentrator” is.
There is such a thing as a “chemical oxygen generator”, like they typically use for the emergency oxygen masks on airplanes. Those are quite hazardous, because in addition to oxygen, they produce immense amounts of heat, easily enough to start fires. (They also “generate” the oxygen from a solid “fuel” material, which makes them one-time-use emergency devices only.)
