At 6 a.m., in the small city of Qikara on the plateau. Aunt Li woke up and immediately felt a slight dizziness – this was her usual condition after moving here to stay with her daughter during her pregnancy. But since a suitable home oxygen generator was purchased at home, her morning discomfort has significantly improved. Her daughter said with a smile, “Mom, this machine is much more convenient than an oxygen cylinder. It can even be taken along for the prenatal check-ups!”
Families like Aunt Li’s are increasingly realizing that a reliable oxygen generator is not an optional item, but a necessary one for maintaining good health.
1.LS-J-02A: Standard universal model, ensuring basic oxygen supply with peace of mind
Suitable for users with limited budgets and those who only need low-flow oxygen inhalation on a daily basis (such as elderly people with mild hypoxia).
- Oxygen flow rate: 1–6L/min (adjustable manually)
- No atomization, no cumulative timing
- Advantages: Simple structure, low failure rate
- Application scenarios: Home daily health care, auxiliary oxygen inhalation in plain areas
Recommended users: Retired elders, patients with stable chronic bronchitis
2.LS-J-02B: Standard atomization type, one machine for two purposes, more practical
Adding the atomization function to the LS-J-02A, it is suitable for users who need to undergo atomization treatment simultaneously.
- Oxygen flow rate: 1–6L/min (manual)
- Supports atomization inhalation
- Advantages: Saves the cost of purchasing an atomizer separately
Target population: Asthma children families, COPD patients
3. LS-J-02C: High-end timing model, providing more precise and scientific management
Upgrade to 9L/min high flow rate and add cumulative usage time recording to facilitate doctors’ assessment of oxygen use compliance.
- Oxygen flow rate: 1–9L/min (manual)
- No nebulization, but with cumulative timing
- Advantages: Satisfies moderate to severe hypoxia needs, data is traceable
Recommended users: Patients with pulmonary fibrosis, post-operative rehabilitators
4.LS-J-02D: High-end atomization + timer type, the all-round choice
It integrates three key functions: high flow rate, atomization, and timing. It is an ideal configuration for a home medical station.
- Oxygen flow rate: 1.5 – 9 L/min (starting at a higher level for greater stability)
- Combined with both atomization and cumulative timing
- Advantages: One device covers various treatment scenarios
Target users: Multi-generational families, residents living in high-altitude areas
5.LS-J-02E: Intelligent electronic control type, full of technological vibe
It adopts five-level electric flow regulation, without the need for manual knobs, making the operation more convenient (especially suitable for those with hand difficulties).
- Oxygen flow rate: 1.5–9L/min (electric five levels)
- No atomization, but with cumulative timing
- Advantages: Precise oxygen control, user-friendly interface, noise optimization
Target users: Pregnant women (【Home oxygen concentrator recommended for pregnant women】), high-end users
6.Five Common Features: Safe and reliable, fully compatible across all scenarios
All models adopt the PSA pressure swing adsorption technology, with consistent core parameters:
- Oxygen concentration: 30%–90% (the lower the flow rate, the higher the concentration; ≥ 90% at 1–3L/min)
- Noise: ≈ 48dB (lower than the ambient noise of a library)
- Dimensions: 364×360×203mm, net weight 6.2kg (【Car-mounted household dual-purpose oxygen generator】can be easily placed in the trunk)
- Negative oxygen ions: ≥ 600 million/cm³ (enhances the freshness of the air)
- Power supply: AC 110V or 220V
- Oxygen inhalation methods: earbud style and nasal inhalation style

[Success Case Sharing]
- Highland Family: Mr. Wang from Nanchuguan, Xizang purchased the LS-J-02D, which solved the altitude sickness problem for his entire family. His child no longer had frequent headaches when going to school.
- Pregnancy Support: Ms. Zhang from Chengdu used the LS-J-02E during pregnancy. The doctor affirmed its blood oxygen stability and she successfully gave birth.
- Vehicle Emergency: Mr. Liu, who was driving the Sichuan-Tibet route, carried the LS-J-02C. At the 5000-meter pass, it promptly relieved acute hypoxia.
