Yes, it is technically possible to increase the oxygen concentration in a room from 21% to about 24%, but it requires specialized equipment such as an oxygen concentrator or oxygen enrichment systems. Oxygen concentrators are medical devices that take air from the environment and remove other gases from it, providing concentrated oxygen, allowing its content to be raised for a specific person or in a confined space.

However, it should be remembered that increased oxygen concentration above 24% may pose a fire and explosion risk, especially in the presence of spark sources or open flames, and long-term breathing of air with such a composition may cause irritation of the mucous membranes and pulmonary edema. Therefore, the use of enriched oxygen should be carried out under the supervision of a specialist and with appropriate precautions.

Alternatively, in order to naturally increase the oxygen level in the room, you can use potted plants that produce oxygen during photosynthesis, as well as ensure good ventilation and air purity. However, such methods will not increase the oxygen concentration to 24%, but will only improve its quality and freshness.

In conclusion, if you need a significant oxygen enrichment of the air, you should consider buying an oxygen concentrator and using it according to medical recommendations.
