Factors to consider in your buying guide
When reading a buying guide , it's important to look at more than just price. Here are the most crucial points:
-
Performance: How much oxygen can the device deliver, and does it suit your needs?
-
Power and battery: Desktops use power from a wall outlet, while laptops have rechargeable batteries.
-
Noise level: Choose a model that is quiet enough for everyday comfort.
-
Weight: Portable models should be easy to carry, especially if you are active.
-
Ease of use: Display, buttons and settings should be simple.
-
Maintenance: Filters and cleaning should be easy to handle.
Which type is right for you?
-
For stable daily use at home
If you want comfort and stability, a home oxygen concentrator is the best choice. Models like the VH-1, VH-2, and VH-3 are compact and relatively lightweight (≈4.8–5.5 kg), while delivering continuous flow up to 7 L/min. They operate quietly (≤42–48 dB) and have useful features like a nebulizer, humidifier, and remote control. If you need extra capacity and reliability, the Serene 5 offers up to 5 L/min with very high purity (93 ± 3%), as well as wheels, alarms, and CPAP compatibility – albeit at a higher weight (≈16.7 kg). -
For active and mobile users
If flexibility is your priority, a portable oxygen concentrator is the ideal choice. The VP-1 and VP-2 are lightweight (≈2.2–2.75 kg) and easy to carry in a bag or backpack. They operate in pulse mode up to 5 L/min and have a low noise level (≤58 dB). Battery life ranges from 1–3.5 hours depending on settings, and the VP-2 can be equipped with a larger battery for longer use. If you need a continuous flow solution, the VP-6 provides up to 6 L/min with high oxygen purity and very quiet operation (≤45 dB), but is slightly heavier (≈3.6 kg). -
For a balanced lifestyle
Some people choose both: a stationary unit at home for stable, long-term use and a portable unit for daily activities, shopping or social visits. This combination ensures that you always have oxygen support available – both when relaxing at home and when leading an active life.
How to get the most out of your oxygen therapy
Choosing the right device is just the first step. To get the best out of it, follow these tips:
-
Place a stationary unit in a fixed location in your home for easy access.
-
Make sure to charge the battery in a portable model so it's always ready.
-
Keep the unit clean by following the manufacturer's recommendations for filter and maintenance.
-
Use the device as a natural part of your daily routine – it provides freedom and stability.
Frequently Asked Questions (FAQ)
Q. How long does the battery last on a portable device?
A. It depends on the model. The VP-1 runs for approximately 1–3 hours per charge, the VP-2 provides approximately 3–3.5 hours (with the option of a larger battery up to approximately 6 hours), while the VP-6 can be used for approximately 2 hours in continuous mode.
Q.Is an oxygen concentrator difficult to operate?
A.No, most models are easy to use. Home units like the VH-1, VH-2 and VH-3 have remote controls, LED/LCD panels and voice guidance, while portable models like the VP-1 and VP-2 have touchscreen displays and intuitive buttons.
Q.How much noise does the device make?
A. Stationary models operate very quietly – down to 42–43 dB (e.g. VH-3 and Serene 5), making them suitable for nighttime use. Portable models range from ≤45 dB (VP-6, very quiet) to ≤58 dB (VP-1 and VP-2).
Q.Does the device need to be cleaned frequently?
A.Yes, the filters should be cleaned or replaced as needed. Several home models have advanced filtration systems (e.g. 8-layer filter in VH-2 or 10-layer filter in VH-3) which make maintenance simple and ensure long life.
Takeaway
When choosing an oxygen concentrator , you should first determine whether your needs lie in stability at home, flexibility on the go, or a combination of both. Stationary units provide reliability and peace of mind at home, while portable models provide freedom and mobility. The table of specifications in the article will help you compare features, noise levels, weight, and battery life, so you can choose the solution that best suits your lifestyle.
