Understanding Portable Oxygen Generators: A Buyer’s Guide

Portable oxygen generators, also known as Portable Oxygen Concentrators (POCs), are life-changing devices for people who require supplemental oxygen therapy. They offer freedom and mobility to those who would otherwise be confined to bulky tanks. However, navigating the world of POCs can be overwhelming. This guide will equip you with the knowledge to make informed decisions about purchasing a portable aquaculture oxygen generator.

What are Portable Oxygen Concentrators (POCs)?

Unlike traditional oxygen tanks, POCs don’t store oxygen. Instead, they use a process called Pressure Swing Adsorption (PSA) to separate oxygen molecules from the surrounding air. The concentrated oxygen is then delivered to the user through a nasal cannula.

Benefits of Portable Oxygen Concentrators

  • Freedom and Mobility: POCs are lightweight and portable, allowing you to maintain an active lifestyle.
  • Continuous Flow: Unlike traditional tanks that deliver oxygen in bursts, most POCs provide a continuous flow.
  • Quiet Operation: Many POCs operate at a whisper-quiet level, making them discreet for everyday use.
  • Rechargeable Batteries: Most POCs come with rechargeable batteries, eliminating the need for frequent tank refills.

Who Needs a Portable Oxygen Concentrator?

POCs are prescribed by doctors for patients with chronic respiratory conditions like COPD, emphysema, pulmonary fibrosis, and sleep apnea. A doctor will assess your oxygen needs and determine if a POC is right for you.

Factors to Consider When Buying a POC

  • Oxygen Flow Rate: The amount of oxygen you need is measured in liters per minute (LPM). Your doctor will determine the appropriate flow rate for your specific needs. Ensure the POC you choose can deliver that flow rate.
  • Weight and Portability: Consider the size and weight of the POC, especially if you plan to be active. Look for models that are lightweight and come with carrying cases or backpacks for easy transport.
  • Battery Life: Battery life is crucial for maintaining mobility. Choose a POC with a battery life that meets your needs, considering factors like flow rate and activity level. Many models offer extended battery options or come with additional batteries.
  • Noise Level: A quiet POC is essential for maintaining a comfortable daily life. Look for models with noise level specifications in the decibel (dB) range.
  • Ease of Use: The control panel should be clear and easy to navigate. Features like alarms and alerts can be helpful for monitoring oxygen levels.
  • Durability: Choose a POC from a reputable brand known for reliable products.
  • Warranty: A good warranty provides peace of mind in case of malfunctions.

Additional Considerations

  • Travel: Airline regulations regarding POCs can vary. Check with your airline well in advance to understand their specific requirements.
  • Stationary Use: While POCs are designed for portability, some models can also be used at home with AC power.
  • Cost: POCs are medical devices and can be expensive. Insurance may cover some or all of the cost. Check with your insurance provider to understand your coverage.

Where to Buy a Portable Oxygen Concentrator

POCs are typically purchased through a durable medical equipment (DME) supplier. Your doctor can recommend a reputable supplier in your area. These suppliers can help you choose the right POC for your needs and guide you through the insurance approval process.


Portable oxygen concentrators offer a new level of freedom and independence for people who require supplemental oxygen therapy. By understanding your needs and considering the factors mentioned above, you can make an informed decision when purchasing a POC. Remember, consulting with your doctor is crucial to ensure a POC is the right solution for you and to determine the appropriate specifications for your specific condition.
