An oxygen concentrator allows a person that has difficulty breathing or needs to have a pure stream of oxygen to be able to receive oxygen-enriched streams of oxygen. Users will often have a hose length of 50 feet or less, so that they can wear their oxygen directly in their nose while being able to move around the house.
Medical oxygen doesn’t have to be cumbersome or inconvenient.
Users can ensure that they have an easier life with enhanced mobility and do so with the oxygen they need to breathe comfortably.
A portable oxygen concentrator is designed to provide oxygen therapy to those with respiratory issues or people who have difficulty breathing at higher altitudes. These devices are similar to at-home concentrators, but are much smaller in size and highly portable.
If you’re in need of an O2 concentrator, you may not know which unit to buy. We’re sharing our top five picks to help make your decision easier. All of these units are reliable, durable and easy to use.
1. Vogvigo Portable Oxygen Concentrator

The unit features PSA (Pressure Swing Adsorption) technology. Oxygen concentration ranges from 30% to 93%, and is adjustable.
With dimensions of 13.39″ x 7.09″ x 12.21″ and weight of 14 pounds, this portable oxygen machine is compact and easy to take on-the-go. It’s whisper quiet, too, operating at just 45db.

The only complaint with this model is that it’s not battery operated. This may limit where you can use the machine. Car adapters can be purchased separately.
Aside from this one caveat, the Vogvigo oxygen concentrator is powerful, easy to use and small enough to take on-the-go.
2. Denshine 1L Portable O2 Compressor
Denshine portable O2 compressor offers an adjustable flow and high oxygen concentration for on-demand oxygen.
This unit offers oxygen concentrations up to 90% and adjustable flow between 1L and 5L. The Denshine machine is also quiet and operates at just 45db.
The compressor pressurizes the air, which is then processed to remove dust, oil, water and other impurities. The unit then cools the air to a comfortable temperature. From here, the air moves into the adsorption tower where carbon dioxide and nitrogen are adsorbed. The end result is high purity O2.
Denshine’s unit offers concentration of 30%-90% with O2 concentration of 90% (suitable for people with asthma and repiratory disorders), 30% (suitable for office and school settings) and 21%.
The unit comes with an earphone-style inhalation device, O2 tube and nasal suction O2.
- Compact and easy to carry
- Highly portable
- Offers adjustable oxygen concentrations of 30%-90%
- Adjustable flow between 1L and 5L
- Small volume
If you’re in need of a high-volume concentrator, the Denshine unit may not be a good fit for you.
With that said, the small volume of this model makes it a great choice for a portable concentrator.
3. Zorvo 1L Portable O2 Generator
The Zorvo 1L generator is the smallest portable oxygen concentrator on our list, but don’t let its small size fool you. This model offers oxygen concentration up to 29% and up to eight hours of continuous operation.
The unit offers an airflow outlet of up to 1.5L.
The Zorvo is a little louder than other units, operating at 50db. But this model does come with some extra features, like a carry bag, that make it easier to transport this machine.

- Carrying case included
- Oxygen concentration isn’t very high
The Zorvo unit doesn’t offer as high of an oxygen concentration as other models on our list. That being said, this machine is small and designed for on-the-go use.
If you don’t require a high oxygen concentration machine and you want a portable unit, Zorvo’s portable O2 generator is a great option.
4. Yuwell YU300 Portable Oxygen Bar Machine

- Not intended for medical use
The reason this device is called an oxygen bar is because it’s not intended for medical use. If you need an oxygen concentrator for medical purposes, talk to your doctor before buying this machine.
Aside from this minor issue, the YU300 is a reliable, durable and portable oxygen generator with high-end features.
5. Enshey Oxygen Bar Machine
The Enshey oxygen bar machine is similar to the YU300 in that it’s not really designed for medical use. This machine offers oxygen concentration up to 90% and a flow between 1L and 5L.

All five of these models are great options if you’re looking for an oxygen concentrator. Just make sure that you consult with your doctor before buying any machine that you intend to use for medical purposes. Some of these models are just designed for therapeutic purposes and may not meet your medical needs.
