The right POC can grant you more mobility and independence and enhance your quality of life.
Introduction
So you have just been prescribed oxygen therapy. What now? Many people fear losing their mobility and independence when they start oxygen therapy, but with the power of portable oxygen concentrators (POCs), you can maintain your lifestyle and still do the things you love. Portable oxygen concentrators in 2025 are better than ever - they are lightweight, compact, and eliminate the need for heavy oxygen tanks that need constant replacement. Read on to learn about the most important features of POCs and the top 5 most popular units of 2025.
Key Features to Consider When Buying a POC
Oxygen Output and Flow Settings
Output and delivery methods are the most important factors when selecting a POC. Most portable devices deliver pulse dose and continuous flow settings of 2 LPM or less. If you require higher oxygen levels, a portable concentrator may not be the right choice, as the most lightweight units usually have to sacrifice higher oxygen output for portability.
Pulse Dose vs. Continuous Flow
Pulse dose flow (demand flow) delivers oxygen in short bursts each time the patient inhales. A concentrator with pulse dose settings automatically detects inhalation and delivers oxygen based on the timing of the breath. Pulse dose flow is generally recommended for those with oxygen needs that fluctuate throughout the day or varying activity levels.
Continuous flow provides a constant stream of oxygen, regardless of the patient's breathing pattern. Continuous flow rate is usually measured in liters per minute (LPM). This flow rate is typically suggested for patients with low resting oxygen levels or needing oxygen at night.
Not all POCs are created equal. Many primarily offer pulse dose settings, while others provide pulse dose and continuous flow with a limited LPM range. When choosing your POC, consider your oxygen needs and your doctor's recommendations. Additionally, consider how you will use the oxygen. Will you use your POC for occasional trips or for traveling long distances? Do you need oxygen while you sleep? Consult your doctor to determine what you should look for when buying your unit.
Battery Life
For an active individual, a POC with around 3 to 6 hours of battery life is usually best. However, that may vary depending on your activity level.
Another factor to consider is whether the POC contains an internal battery, an external battery, or both. With an internal battery, you will only have to plug it in to charge, however, if there is not a power source available, this could be a problem. An external battery port typically requires carrying additional batteries, increasing the weight of your bag, but it solves the common problem of finding a power source while on the go.
Weight
Most portable concentrators should be lightweight enough to carry easily (4 - 8 pounds), but some weigh more depending on the model and their oxygen output level. Many portable concentrators can be taken in a carry bag or case; others require a mobile cart. Consider your activity and mobility level when selecting your concentrator, especially if you are on the go frequently.
Noise Level
The average home noise level is around 40 - 50 decibels1. Choose a POC with a decibel level of 40 or lower for discreet use at home or on the go.
FAA Compliance
Choosing an FAA-approved unit is vital if you frequently travel, especially by plane. Even train, bus, and cruise lines may require FAA-approved POCs.

Why Portable Oxygen Concentrators Are Essential for an Active Lifestyle
Portable oxygen concentrators have revolutionized the way patients use oxygen therapy. While powerful and beneficial, stationary oxygen concentrators can be a challenge for those wanting to maintain an active lifestyle. Portable concentrators eliminate the inconvenience and struggle of feeling tethered to your primary oxygen source at home or transporting cumbersome oxygen tanks.
POCs increase mobility and independence by enabling users to take their oxygen therapy anywhere while traveling, running errands, going to the gym, and more. They are made to be lightweight and easy to carry, allowing you to go about your daily routines while still getting the oxygen you need. Portable concentrators can improve your overall quality of life with the freedom and independence they provide, enabling you to get back to doing what you love and spending time with the people you care about most.
Tips for Maintaining Your Portable Oxygen Concentrator
Weekly Cleaning and Maintenance
1. Clean the exterior:
- Unplug your POC from any power source and detach accessories
- Wipe down the exterior with a damp washcloth and mild soap. Take care to avoid getting water or soap in any ports.
2. Remove and clean the filters:
- Fill your sink or a basin with warm, soapy water and submerge the filter.
- Gently wipe away dust and debris with a washcloth, and let it air dry on a clean towel.
3. Clean and inspect nasal cannulas:
- Disconnect cannula and tubing from the concentrator.
- Inspect for any damage or wear (if there is any damage or wear, dispose of and replace with a new one).2
- Rinse gently with warm water and soak in warm, soapy water for around 10 - 15 minutes for thorough disinfecting.
- If there is any stubborn dirt or mucus, use a small brush (like a clean toothbrush) to gently scrub away remaining debris.
- Pat down the cannula with a lint-free towel.
- Hang the cannula in a safe place to finish air drying.
General Battery Care and Tips
- Use only manufacturer-recommended batteries.
- When storing batteries, keep them in a cool, dry place and out of direct sunlight.
- Follow manufacturer guidelines for charging your unit. It is generally recommended not to undercharge or overcharge batteries, but guidelines on maintaining battery levels vary depending on your unit. Consult the user manual for specific instructions on how to properly charge your battery.
- Don't leave a battery dormant for more than 90 days.
Properly Storing Your Concentrator
- When not in use, store your concentrator in its designated protective carry case in a dry, room-temperature place.
- Never store your concentrator with a drained battery. Storing on an empty charge can shorten the overall life of the battery.
- If stored for more than 4 weeks, take out the concentrator to wipe away any dust or debris that may have settled on the unit.
Protecting Your Concentrator While Traveling
When taking your concentrator on the go, protect your unit by carrying it in its designated protective case. These cases are often specifically designed to cushion the unit and may even have pockets and pouches made for its accessories. If using a different bag or case, ensure your POC and any fragile components are stored in a padded pouch or compartment.
Where to Buy the Best Portable Oxygen Concentrators
When it's time to finally buy an oxygen concentrator, it is vital to buy your unit from a reputable, trusted source. There are several places from where you can purchase your unit:
