How to Choose the Right Oxygen Concentrator for Your Needs
How to Choose the Right Oxygen Concentrator for Your Needs
Buying an oxygen concentrator can feel overwhelming because most people are trying to solve two problems at the same time.
-
Getting the right oxygen support for their prescription and comfort
-
Choosing a device that actually fits real life, like moving around the house, running errands, or traveling
This guide helps you choose step by step in plain English. This is educational only, so always confirm your specific needs with your clinician or oxygen provider.
Step 1: Start with your prescription and your real day to day routine
Before looking at brands, get clear on two things.
-
What your clinician prescribed
This can include oxygen delivery type and flow requirements, plus when you need oxygen (sleep, exertion, all day, travel, etc.). -
When and where you will use it
Ask yourself:
• Do I need it only at home, or also outside
• Do I need it for short errands, or for longer days out
• Do I care most about weight, battery flexibility, or having more delivery options
Most people end up shopping twice when they skip this step, because the lightest unit is not always the best match, and the strongest unit is not always the most practical.
Step 2: Portable vs home concentrators
In general, there are two categories.
Home concentrators
These are built to stay in one place. They are usually larger and not meant to be carried around.
Portable oxygen concentrators
These are built for mobility. Most people choose a portable concentrator when they want freedom to leave the house, move between rooms, or travel with fewer limitations.
Your current lineup is focused on portable oxygen concentrators, so this guide will emphasize what to look for when choosing a portable unit.
Step 3: Pulse dose vs continuous flow
This is one of the most important decisions, and also one of the most misunderstood.
Pulse dose
Pulse dose devices deliver oxygen in bursts, typically timed to your breathing. Many portable concentrators use pulse dose because it helps keep devices smaller and battery friendly.
Examples to compare on our store:
• Inogen One G5 Portable Oxygen Concentrator
• OxyGo Next Portable Oxygen Concentrator Refurbished
• Inogen One G4 Portable Oxygen Concentrator Refurbished
• Inogen One G3 Portable Oxygen Concentrator Refurbished
• Rhythm P2 Portable Oxygen Concentrator
Continuous flow
Continuous flow devices deliver a steady stream of oxygen. Some people specifically need continuous flow depending on their prescription and how they use oxygen.
A commonly selected option to compare is:
• Philips Respironics SimplyGo Portable Oxygen Concentrator Refurbished
Important: This is not something to guess. If your prescription or clinician indicates continuous flow, choose accordingly.
Step 4: Think in “use cases” instead of specs
A lot of shoppers get stuck comparing numbers and forget the real question: what will this feel like to use every day?
Here are the most common use cases and what typically matters most for each one.
If you want something simple for errands and daily mobility
Focus on:
• Easy to carry
• Easy to operate
• Comfortable for short to medium outings
Good matches many shoppers consider in this category:
• Rhythm P2 Portable Oxygen Concentrator
• Philips Respironics SimplyGo Mini Refurbished
If you want flexibility for longer days out
Focus on:
• Battery options and flexibility
• Comfort during extended use
• A device you can grow with as your routine changes
Options to compare:
• Inogen One G5 Portable Oxygen Concentrator
• Inogen One G5 Portable Oxygen Concentrator Refurbished
• OxyGo Next Portable Oxygen Concentrator Refurbished
If you want a more budget friendly way into portability
If you want portability but want to control cost, refurbished units are often a smart path as long as you are buying from a reputable seller with clear condition details and support.
Two options people often compare:
• Inogen One G3 Portable Oxygen Concentrator Refurbished
• Inogen One G4 Portable Oxygen Concentrator Refurbished
If you specifically need continuous flow capability in a portable unit
In that case, start your comparisons here:
• Philips Respironics SimplyGo Portable Oxygen Concentrator Refurbished
Step 5: Battery life, charging, and travel reality
Battery life is never one single number. It changes based on settings, how you breathe, and how you use the device throughout the day. That is why it is better to think about your routine.
Ask yourself:
• Do I need this for short errands or longer days
• Do I have easy access to charging during the day
• Am I traveling by car, flying, or both
If travel is part of your plan, a portable concentrator is usually the right direction. Many travelers compare:
• Inogen One G5
• Philips Respironics SimplyGo Mini Refurbished
• OxyGo Next Refurbished
Always confirm airline and battery rules before flying, because requirements can vary.
Step 6: Comfort details people forget to check
Specs matter, but comfort is what decides whether you actually use the device confidently.
Pay attention to:
• Noise level in quiet rooms
• How it feels to carry it for 30 to 60 minutes
• How simple it is to change batteries or charge
• Whether you prefer a shoulder bag style carry or another setup
If you are sensitive to weight and carrying comfort, compare models like:
• Rhythm P2
• SimplyGo Mini Refurbished
Step 7: New vs refurbished
Since we offer both new and refurbished oxygen concentrators, you can choose what matters most to you.
When buying new makes sense
New is often best if you want:
• Maximum peace of mind
• A fresh start with a brand new unit
• Strong preference for new condition
Examples to compare:
• Inogen One G5 New
• Rhythm P2 New
When refurbished can be a smart choice
Refurbished is often best if you want:
• Better value while still getting a quality unit
• Access to higher end models at a lower cost
• A practical option for backup or travel

• Inogen One G5 Refurbished
• OxyGo Next Refurbished
