What does oxygen-enriched hotel mean?

Oxygen-enriched hotels refer to hotels with sufficient oxygen.

Oxygen-enriched hotels deliver high-oxygen air directly to rooms through oxygen generators, forming an artificial oxygen-enriched environment.

Oxygen enrichment is to collect oxygen in the air by physical or chemical methods, so that the oxygen content in the collected gas is greater than or equal to 2 1%.
