Product Specialist: Emma Clark
Clinical Applications Specialist: Dr. James Bennett

Inogen Rove6 concentrators' popularity in the market is unrivaled. However, the cost for Inogen Rove6 may not fit everyone's budget. The product may also fail to meet your oxygen needs as per the prescription. 

The best alternatives to Inogen Rove6 are Caire Freestyle Comfort & ReadyO2 Pro. Ready O2 Pro comes cheaper and has high oxygen output levels. Caire Freestyle Comfort has a longer battery life and more innovative Features.

We have researched and tested various POC models from different manufacturers. Our findings can enable us to provide credible information regarding these models in the same operating range.

Please continue reading to find some of the best Inogen alternatives on the market.

Why Consider an Inogen Alternative?

For various reasons, you may consider an Inogen alternative as a patient or a medical specialist. The main aim of using a POC is to enhance oxygen absorption in the bloodstream. A portable oxygen concentrator saturates a patient's lungs with oxygen, increasing the absorption rates. 

Cost, features, and specific medical needs play a vital role when choosing any medical device. You will need to compare different products in the market to make the right choice. Inogen products may vary from other models in price, weight, battery life, and output levels.

What to Look for in an Inogen Alternative

A medical device should support the patient's needs towards recovery. It must also enable a patient to lead a quality life. However, POCs' upfront cost is high compared to traditional oxygen tanks. But, the devices eliminate the need for frequent oxygen refills, and most are FAA-approved for air travel.

So, what should you look for in an Inogen alternative? There are various features to look for when selecting a medical device. Portable oxygen concentrators help patients to lead an active life during oxygen therapy.

Here are the features you should consider when looking for an Inogen alternative:

Weight

When selecting a portable oxygen concentrator, the device weight should be at your list. The heavier the device, the more load you must bear when using the model. A Lightweight alternative for Inogen that can give you the necessary oxygen needs is ideal.

Oxygen Output

Your physician's prescription determines the oxygen output levels you need. Different POC models output varying volumes using either continuous or pulse flow modes. Depending on your doctor's supplemental oxygen needs, you can choose an Inogen alternative that fits the patient's needs.

Battery Life

Your device's battery life is critical. A model with a lower battery life can limit your outdoor activities. A model like Caire Freestyle Comfort has a battery lasting up to 16 hours.

Noise Level

Wearing a POC with audible noise can attract attention. The noise makes you self-conscious, as well as others. Such a device may discourage a patient from engaging in social activities. You can also look for an Inogen alternative that is less audible.

Price

Inogen products are good and popular, but their prices are high. However, other portable oxygen concentrator innovators are developing cheaper products with similar or higher specs.

Importance of choosing the correct device based on lifestyle

  • Travel: If you select the right device, it eases movement in your day-to-day activity. A device that is FAA-approved also enables you to travel by air.
  • Home use: The right device will allow you to use it while away and at home. The device should support a patient while asleep or resting and when active. We recommend using a stationary concentrator at home and POC when out.
  • Medical stability: The use of supplemental oxygen is for medical reasons. Having the proper POC enables a patient to undergo therapy per the doctor's recommendation.

How to Choose the Right Alternative for You

When choosing the right alternative POC model, you should consider several factors. Here is how to select the correct alternative:

  • Medical needs: Different models have varying output levels and delivery modes. You should choose an alternative that will cater to your oxygen needs. Your chosen POC should match your healthcare provider's prescription during the oxygen therapy.
  • Lifestyle: Are you an active person? You will need an oxygen concentrator that you can carry around easily. Choose a lightweight model. Less mobile patients can use a home oxygen concentrator. You'll need an alternative with a long battery life if you are active outdoors.
  • Portability: Your body needs oxygen supply whether you are active or resting. Portable oxygen concentrators allow you to continue being active, thus improving your quality of life. Some devices are less weighty and more comfortable when carrying in shoulder bags.
  • Your budget: Although you can't compromise your health over money, financial abilities differ. When choosing the right alternative, the cost of the device is also a significant consideration. Cheaper POC models will offer you the same value as the high-end brands.

Tips for testing and comparing different models:

  • Oxygen concentration levels
  • Oxygen output volumes
  • Battery life
  • Battery recharge duration
  • Comfort when carrying the device
  • Operational altitude
  • Device weight
  • Ergonomic design

Conclusion

The above portable oxygen concentrators can work as an Inogen Rove6 alternative. 

When deciding on a POC model, look for the features that will help improve your quality of life.

However, you should not compromise on the oxygen output of the device as it may affect the amount of oxygen you are receiving.

If you're looking for an Inogen alternative with the best value for money, go for ReadyO2 Pro.
