Meeting the Needs of Different Groups of People

Plateau Travel and Outdoor Sports Enthusiasts
For travelers and outdoor enthusiasts who frequently visit high altitude areas, altitude sickness, such as headaches, nausea, and shortness of breath, can be easily experienced at altitudes above 3,000 meters. Prompt oxygen inhalation is crucial for relief. Our portable oxygen concentrator is designed specifically for high-altitude use. Weighing only 1.75 kg and equipped with a dedicated backpack, it’s easy to carry while hiking. It comes with a car adapter for self-driving oxygen supply needs, and a battery mode eliminates reliance on a fixed power source, making it reliable even in remote scenic spots and campsites without an external power source. It boasts an oxygen concentration of 93% ± 3%, ensuring efficient oxygen delivery. It also features a “High Altitude Mode” optimized for high-altitude, low-pressure environments, providing continuous and stable oxygen delivery at altitudes above 5,000 meters. It also supports automatic flow adjustment from 1 to 9 liters/minute, effectively and instantly relieving both mild and severe hypoxia symptoms, providing a safe and secure travel experience at high altitudes.

Patients with Respiratory Diseases
For patients with respiratory conditions, our oxygen concentrator delivers reliable oxygen concentrations up to 93% ± 3% within a flow range of 1 to 9 liters per minute. This feature directly increases the oxygen content of the patient’s inspired air, thereby alleviating desaturation caused by impaired ventilation or gas exchange—common in conditions such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, and acute asthma attacks. In this way, it alleviates symptoms associated with hypoxia, such as dizziness, fatigue, palpitations, and cyanosis (bluish discoloration of the lips).

Elderly People Who Need to Go Out
For seniors who frequently go out, daily activities like climbing stairs and visiting parks increase oxygen consumption, leading to the common symptom of shortness of breath on exertion. Without timely oxygen replenishment, symptoms such as dizziness, palpitations, and even fainting can jeopardize their daily safety.Our oxygen concentrator is specifically designed to meet this need for on-the-go oxygen supply. Weighing only 1.75 kg, it’s lightweight and portable, allowing seniors to easily slip it into a backpack and carry it without feeling burdened. Its 4-hour battery life ensures sufficient power while on the go, maintaining a stable oxygen concentration of 93% ± 3%. This means seniors can continuously receive oxygen while walking, allowing them to receive oxygen therapy anytime, anywhere, whether going to the hospital for a follow-up appointment or shopping at the market, making daily travel more comfortable and worry-free.

People Troubled by Air Pollution and Haze
For those plagued by air pollution and smog, invisible threats in the air, such as PM2.5 particles and harmful gases, pose a real threat to respiratory health. These pollutants adhere to the lining of the respiratory tract, interfering with the alveoli’s ability to effectively exchange oxygen and carbon dioxide. Over time, this interference can lead to indirect hypoxia, causing fatigue or shortness of breath.Our oxygen concentrator utilizes advanced molecular sieve technology to independently generate high-concentration oxygen (consistently maintaining 93% ± 3%) without inhaling ambient polluted air. On smoggy days when outdoor air quality plummets, users can simply connect a nasal cannula to directly inhale pure oxygen, reducing the amount of polluted air they inhale and alleviating stress on their respiratory system.

Intellectual Workers and People Who Stay Up Late
For those who engage in intellectual work or frequently stay up late, high-intensity mental activity causes the brain to consume more oxygen than usual. This excessive oxygen consumption can easily lead to symptoms such as dizziness and decreased concentration, which can affect work and study efficiency.Our oxygen concentrator is ideally suited to addressing this “mental oxygen deprivation” problem. It features a compact and portable design, weighing only 1.75 kg, and provides an adjustable oxygen flow rate of 1 to 9 liters per minute, flexibly meeting diverse needs. Once connected to a power source, it takes up minimal desk space, making it easy to use even while working or studying at a desk. Its battery mode is particularly convenient in environments without power outlets, such as meeting rooms and libraries, providing a convenient, on-the-go oxygen supply.

Product Features

Lightweight and Portable
This portable oxygen concentrator weighs only 1.75kg and can be easily lifted with one hand. Whether you put it in a backpack, handbag, or hold it directly in your hand, it will not add any extra burden. You no longer need to be restricted by the heavy traditional oxygen concentrator when traveling, and completely say goodbye to the cumbersome feeling of “dragging the machine around”.

Stable High Oxygen Concentration
Our oxygen concentrator offers adjustable flow settings from 1-9 and maintains an oxygen concentration of 93% ±3% at all flow levels and operating modes, ensuring a pure and reliable oxygen experience.

Three Modes of Oxygen Supply
Our oxygen concentrator has three operating modes:
● Pulse Mode: Automatically detects respiratory rate, delivering oxygen during inhalation, up to 99%, and stopping during exhalation.
● Constant Frequency Mode: Continuously delivers oxygen every 1.4 seconds, suitable for environments requiring stable oxygen flow.
● High Altitude Mode: Provides a stable oxygen supply even at altitudes of 5,000 meters and in low temperatures.

Ultra-Long Battery Life
Our oxygen concentrator uses a large-capacity lithium-ion battery. After a quick charge of approximately 2.5 hours, it can provide up to 4 hours of continuous use. The removable battery design allows for quick replacement and can also be charged via a household wall outlet or a car power outlet, making it suitable for home care, long-distance travel, and outdoor activities.

Eight-layer Deep Filtration System
Our oxygen concentrators are equipped with an eight-layer deep filtration system, providing full-chain protection from air intake to oxygen output. This effectively removes dust, formaldehyde, PM2.5, pollutants, and oil smoke from the air, ensuring oxygen purity. The output oxygen meets medical-grade cleanliness standards, making it suitable for the elderly, sensitive individuals, and those who inhale oxygen long-term.

Portable Backpack
Our oxygen concentrators come with a dedicated carrying bag, custom-designed to fit the concentrator’s dimensions and securely secure against bumps and knocks. Made of lightweight, wear-resistant fabric and featuring adjustable shoulder straps, it makes carrying your oxygen concentrator even more convenient. It also prevents the concentrator from getting hot and accessories from getting lost, making it a hassle-free way to enjoy oxygen.

3.5-inch Color LCD Touchscreen
This oxygen concentrator features a 3.5-inch touchscreen that clearly displays settings, mode, flow rate (oxygen concentration, flow), time, and analysis information, making operation intuitive and easy.

Multiple Security Alarm Systems
This oxygen machine features a built-in multi-level safety alarm system that monitors device status in real time. If any alarms occur, such as excessive temperature, low battery, compressor anomaly, battery overheating, low oxygen concentration, or no breathing, a dual audible and visual alarm will sound until the hazard is resolved. This is particularly suitable for those who rely on oxygen therapy for a long period of time, eliminating the need to monitor the device closely, ensuring “safe oxygen inhalation and worry-free use.”

Low Noise
This oxygen machine operates at ≤45dB, equivalent to the sound of someone quietly turning pages in a library, keeping up with ambient noise. It can be used at night without disturbing sleep or waking family members, or during the day without disrupting daily life like watching TV or chatting. It also won’t draw attention to you in public. For those who rely on oxygen for a long time, such as the elderly and those recovering from surgery, this oxygen machine can reduce auditory stress and irritability, ensuring “quiet oxygen inhalation, comfortable living.”
