Oxygen therapy (OPT) refers to treating patients with a gas containing oxygen at a concentration higher than that of the air, primarily to prevent and correct hypoxemia. Long-term oxygen therapy refers to patients with chronic hypoxemia receiving at least 15 hours of prolonged oxygen therapy daily.

Oxygen concentrators (also known as oxygen generators) mainly utilize technologies such as molecular sieve physical adsorption to remove nitrogen and carbon dioxide from the air, separating oxygen. Their main advantages are continuous use and low cost; disadvantages include higher cost, continuous noise and vibration, and the need for regular maintenance. Common oxygen concentrators include: stationary (for home oxygen therapy), portable (for travel), and mobile (for daily life or exercise).

Below are some recommended home oxygen concentrators (oxygen generators) with good reputations and reliable performance for your reference:

**Important Notes:**
• When choosing an oxygen concentrator, it is recommended to select a suitable product based on your own needs (such as whether you require nebulization function, oxygen flow rate, etc.) and your doctor's advice.

• Oxygen concentrators are medical devices; it is recommended to choose products with a medical device registration certificate to ensure safe use.

• Please read the product instruction manual carefully before use and operate and maintain the equipment correctly.
