Choosing the right oxygen concentrator depends on three key factors:

• Flow requirements: mild demand (1-3L/min), moderate demand (3-5L/min), severe demand (5L+)
• Usage Scenarios:
  For long-term home oxygen therapy: Choose a home-use model (stable flow, 24/7 operation support, and some include nebulization features).
  For outdoor/short trips: Choose a portable model (lightweight, long battery life, ideal for temporary oxygen supplementation).
• Functional Preferences: Consider additional features like quiet design (for nighttime use), smart display (real-time oxygen concentration monitoring), and fault alarms (leakage/low oxygen alerts) — balance your budget with practical needs.

Our oxygen concentrators extract oxygen from the air, so there is no need for refills. They are safer than tanks:

• There are no risks associated with high-pressure storage or liquid oxygen handling.
• Portable models eliminate the need to transport heavy tanks, making them perfect for travel.

No, the flow rate must match your condition.

• 2-3 L: Suitable for mild hypoxia or supplemental use.
• 5-7 L is for moderate to severe needs (follow your doctor’s advice).

Overuse may cause discomfort, so never exceed the prescribed flow rate.

Oxygen concentrators are prescribed to manage ​​low blood oxygen levels (hypoxemia)​​, including conditions such as:

• Chronic Obstructive Pulmonary Disease (COPD)
• Asthma (severe exacerbations)
• Cystic fibrosis
• Sleep apnea (when paired with PAP therapy)
• Heart failure (in some cases)
• Pneumonia or other respiratory infections
• Post-surgical recovery requiring supplemental oxygen

​​Important​​: Please purchase and use under the guidance of your doctor.

Some of our oxygen concentrators have internal humidification functions, and some are equipped with humidification bottles to keep the oxygen moist at all times and protect the nasal cavity.

Almost all of our models operate at a noise level of ≤45 dB, which is as quiet as a library, ensuring undisturbed sleep.

Yes, for most models. However, we recommend allowing the unit to cool down for 30 minutes every 12 hours to extend its lifespan, especially for high-flow models (5L/7L).

• Keep ≥ 2m from open flames or flammables (paint, gas).
• Avoid humid/dusty areas (protects internal components like molecular sieves).
• Never block air intakes—ensure 20 cm clearance from walls/furniture.

• Filters: Clean weekly and replace every 3-6 months to prevent reduced oxygen output.
• Humidification Bottle: Change the water daily and clean the bottle weekly with detergent.
• Nasal Cannula: Replace monthly. Clean with warm water (avoid alcohol).
• Batteries (portable models): Charge them fully before first use and store them at a 50% charge if they are idle.

• Empty and dry the humidification bottle.
• Disconnect power, store in a cool, dry place (avoid direct sunlight).
• Recheck filters and cords before reuse.

Our tiered warranty includes:

• Core components (compressor/molecular sieve): 1 year.
• Electronics: 1 year.
• Consumables (filters/cannulas): 6 months.
