OxyGo NEXT vs FIT Plus: Which One Is Better for Your Needs?
There isn't one OxyGo model that is right for everyone. The better choice depends primarily on your prescription, required pulse settings, desired battery runtime and how much weight you are comfortable carrying.
Consider the OxyGo NEXT NG if:
- You need access to pulse settings 5 or 6
- Long battery runtime is a priority
- You are comfortable carrying approximately 4.8 lbs or more
- You frequently spend extended periods away from a power source
Consider the OxyGo FIT Plus if:
- Your prescription can be met within its available pulse settings
- Minimum weight is one of your highest priorities
- You want a smaller concentrator for errands, walking and everyday mobility
- You don't require the longer battery runtime available from the NEXT NG
Your prescribed oxygen needs should come first. A lighter concentrator is not necessarily the better choice if it cannot provide the setting or delivery your healthcare provider has prescribed.
OxyGo Battery Life: What to Know
Battery specifications are useful for comparing portable oxygen concentrators, but advertised maximum runtime should not be interpreted as guaranteed runtime in every situation. Actual battery life can vary based on the oxygen setting, breathing rate, battery condition, temperature and other operating conditions.
For users who routinely spend long periods away from electrical power, the NEXT NG has a significant advantage in maximum available battery runtime. For shorter outings where minimizing weight matters more, the FIT Plus may be more convenient.
Can You Travel With an OxyGo Portable Oxygen Concentrator?
OxyGo portable oxygen concentrators are designed for portable use and OxyGo identifies its portable systems for air-travel use. Airline policies and documentation requirements can vary, so travelers should always contact their airline before departure and confirm current requirements for traveling with a portable oxygen concentrator and lithium-ion batteries.
Can You Use OxyGo While Sleeping?
Both models are designed by the manufacturer for 24/7 use. However, whether a pulse-dose portable oxygen concentrator is appropriate for you during sleep depends on your individual oxygen requirements and prescription.
If you have been prescribed oxygen during sleep, confirm with your healthcare provider that your prescribed device and settings are appropriate for nighttime use.
OxyGo Warranty: NEXT vs FIT Plus
The current OxyGo NEXT NG carries a 5-year standard concentrator warranty. The OxyGo FIT Plus carries a 3-year concentrator warranty. Batteries, sieve columns and other components may have different warranty periods, so buyers should review the applicable warranty terms for the exact model and accessories purchased.
