Oxygen Concentrator Buying Guide

Oxygen Concentrator Types

There are two types of oxygen concentrators: HOCs and POCs. Each has its benefits, but they also have some downsides.

  • POCs are portable devices. This type of device is great if you need to travel with your concentrator or move around frequently because it's light and easy to carry around when necessary
  • HOCs are stationary machines, which makes them more durable than other models because they don't require much maintenance after installation in your home or office space. This type of machine is also ideal if you need larger amounts of oxygen for your treatment because it can produce enough gas to meet your needs.

Features to Consider
When you consider purchasing an oxygen concentrator, you need to take several factors into account. Here are some key features to consider

Oxygen concentration

The most important feature is the oxygen concentration output that the machine can provide. It is usually represented as a percentage, such as 90% or 95%. The higher the concentration, the more effective it will be in delivering oxygen to the user.

Flow rate

The flow rate refers to the amount of oxygen delivered per minute, measured in liters per minute (LPM). Different individuals may have different oxygen needs


Portability is a crucial factor, especially for people who need to use oxygen concentrators while on the move or traveling. Portable oxygen concentrators are lightweight and have long-lasting batteries, allowing users to maintain their oxygen therapy even outside of their homes.

Noise level

Many oxygen concentrators produce noise during operation. It is important to consider the noise level, especially if you intends to use the machine in a quiet environment or during sleep. Some models are specifically designed to be quiet and provide a more peaceful experience for the user.

Power source

Oxygen concentrators require a power source to operate. It is essential to determine whether the machine operates on electricity, battery, or both. Consider the availability of power sources in the user's home or travel destinations.


Humidification is essential for individuals using supplemental oxygen, especially if worn continuously. It helps alleviate the issue of dry noses that can arise from extended use. If you require a higher flow rate of oxygen, wear it around the clock, or have concerns about nasal dryness, it is recommended to consider an oxygen concentrator with a humidification feature


Regular maintenance is necessary to keep the oxygen concentrator functioning optimally. Look for models with easy-to-clean filters and other components that can be easily replaced. Consider the availability of maintenance services or spare parts in the user's area.

Alarms and safety

Ensure that the oxygen concentrator has built-in safety features such as oxygen purity alarms, power failure alarms, and overheating protection. These features help ensure the user's safety and provide a warning in case of any malfunctions.

Cost and insurance coverage

The cost of the oxygen concentrator is an important consideration. Compare prices, warranty periods, and after-sales services. Additionally, check if the device is covered by insurance or any health programs, as it can significantly reduce out-of-pocket expenses for the user.
