We provide portable oxygen concentrators and stationary oxygen concentrators to meet the different needs of various users.

• Portable Oxygen Concentrators: Featuring a lightweight design, they can be carried around or used in cars. Powered by a built-in battery, they are ideal for travel and short-term use.
• Stationary Oxygen Concentrators: Plug-in for home use, they provide continuous, stable oxygen flow and can operate continuously 24/7. They run quieter, and some models support nebulization function and can connect to a ventilator.

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 and oxygen tanks have several key differences.

• Oxygen concentrators extract oxygen from the surrounding air. They never need refilling. You just plug them in or use battery power for portable models and they can operate continuously.
• Oxygen tanks store pre-filled oxygen. They have limited capacity. Once empty, they require regular refills or replacement.
• Concentrators are more cost-effective over time with no ongoing refill costs. They work better for daily extended use. Tanks are typically used for short-term or emergency situations.

No, a higher oxygen flow is not necessarily better. It needs to match your condition.

For example, long-term inhalation of high-flow oxygen can inhibit the respiratory center in patients with chronic obstructive pulmonary disease (COPD). The body relies on hypoxia to stimulate breathing, which can lead to carbon dioxide retention.

Therefore, hypoxia requires dynamic adjustment based on blood oxygen saturation. Increasing the flow rate blindly is ineffective and may increase the body’s burden. You must strictly follow your doctor’s advice.

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

Notice​​: 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.

For portable oxygen concentrators:

• Check that all parts are included (main unit, battery, nasal cannula, etc.) and that none are damaged.
• Fully charge the battery before first use (follow the charging instructions in the manual).
• Attach the nasal cannula correctly to avoid air leaks.
• Turn it on at a low flow rate first to test its operation. Then, adjust it as needed, following your doctor’s advice.
• Read the manual to understand battery life and power-saving modes.

For home oxygen concentrators:

• Place it on a flat, stable surface with at least 20 cm of space around it for ventilation.
• Ensure that the power voltage matches your home supply to prevent damage.
• Fill the humidifier with clean water, but do not exceed the maximum line. Connect it securely.
• Clean the air filter before first use (follow the cleaning instructions in the manual).
• Turn the concentrator on and listen for unusual noises. If you hear any, stop using it and contact support.
• If your model has a nebulizer function, ensure that it is assembled correctly before use.

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

• Our portable oxygen concentrators come with removable batteries. One battery runs for about 2-6 hours, depending on usage and flow rate. If you need longer use or overnight operation, you can buy spare batteries to replace, keeping the concentrator running continuously. This allows portable devices to flexibly extend their usage time.
• Our stationary oxygen concentrators can run 24/7. However, to keep them operating efficiently and extend their lifespan—especially for high-flow models (≥5L/min)—we recommend letting them rest for 30 minutes every 12 hours. A short cooling period prevents overheating and ensures long-term reliable performance.

Posture Tips: 

• Sit upright or semi-reclined: Avoid lying flat, as this can cause nasal secretions to block the oxygen tube or make breathing less comfortable.
• Secure the tube during movement: If you’re walking or moving around, clip the oxygen tube to your collar or clothing to reduce pulling or tugging.

Environment Guidelines: 

• Stay ventilated: Oxygen is flammable, so avoid closed, stuffy rooms (open windows or use fans to keep air flowing).
• Keep away from heat/flames: Stay at least 1 meter (3 feet) away from open flames (candles, stoves), hot surfaces (radiators, heaters), or sparks (lighters, electrical tools).
• Avoid humidity & interference:
  · Stay out of damp areas (like bathrooms)—moisture can damage the device or tubes.
  · Keep away from strong electromagnetic fields (e.g., microwaves, large motors)—these may disrupt the concentrator’s function.

• Outdoor portable use: If using a portable concentrator outside, avoid extreme temperatures (below -10°C/14°F or above 40°C/104°F)—very hot or cold weather can lower its efficiency.

• 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.

Before long-term storage:

• Remove the humidifier bottle, empty it, dry it, and put it back in place.
• Turn off the power and store the power cord safely.
• Do not store the concentrator in damp or dusty areas. Avoid direct sunlight and contamination. Store the oxygen tube and concentrator in a dry place at room temperature. Do not bend the tube and keep the machine out of reach of infants and young children.

Before using it again after long-term storage:

• Check that the power cord is in good condition.
• Clean the oxygen tube and concentrator and check for blockages or bends.
• Clean the humidifier bottle.

Please note the following when placing your oxygen concentrator:

• Do not place it in poorly ventilated areas.
• Place it in a well-ventilated indoor area, away from direct sunlight. Keep it at least 10 cm away from walls, furniture, etc. Avoid placing it near carpets, heaters, electric heaters, or hot air ventilation equipment.
• Do not place it near heat sources, open flames, or hidden fire sources.
• Do not place it in damp, unprotected, smoky, heavily polluted environments, or places with excessively high or low temperatures.
• Do not place debris or containers with water or oil on top of the concentrator.
• Do not place debris under the concentrator, as this may block air inlets/outlets, causing overheating, shutdown, or reduced oxygen concentration.

Our tiered warranty includes:

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