If you're considering a portable oxygen concentrator (POC) for yourself or a loved one, it's natural to have a lot of questions. Whether you're concerned about travel, battery life, or insurance coverage, this FAQ blog covers the most common (and important) things buyers want to know.
Let’s dive into the top questions people ask before buying a portable oxygen machine.
A portable oxygen concentrator (POC) is a medical device that filters air, removes nitrogen, and delivers high-purity oxygen to the user. Unlike traditional oxygen tanks, it doesn’t store oxygen—it produces it on demand.
People with chronic respiratory conditions like:
COPD (Chronic Obstructive Pulmonary Disease)
Pulmonary fibrosis
Emphysema
Post-COVID or pneumonia recovery
Sleep apnea (in certain cases)
Patients recovering from surgery
… may be prescribed oxygen therapy. A POC is especially helpful for people who want to remain active or travel while receiving oxygen.
Yes. In most countries (including the U.S., UK, Canada, and EU nations), you need a doctor’s prescription to legally purchase a portable oxygen concentrator. The prescription ensures the device is tailored to your required oxygen flow rate.
Pulse Dose (On-Demand): Delivers oxygen only when you inhale. It conserves battery and is great for active use.
Continuous Flow: Delivers a steady stream of oxygen, ideal for people who need oxygen during sleep or use CPAP machines.
Tip: Not all portable models offer continuous flow. Choose based on your doctor's recommendation.
Yes—if it's FAA-approved. Most major brands like Inogen, Philips Respironics, and CAIRE produce models certified for in-flight use.
🛫 Checklist:
Confirm FAA approval
Inform your airline in advance
Carry extra batteries (2x flight duration is often required)
Battery life depends on the model and oxygen flow setting. On average:
Pulse dose models: 4 to 8+ hours
Continuous flow models: 2 to 5 hours
Most units allow battery swapping or external battery packs for longer use.
Portable models typically weigh between 2.5 to 7 kg (5 to 16 lbs), including the battery. Some ultra-light models are even lighter than a laptop.
That depends on the model and your breathing pattern:
Continuous flow units are better for sleep.
Some pulse dose models have sleep modes but may not be suitable for everyone.
💡 Always consult your doctor to determine if your machine supports safe overnight use.
Most POCs operate at around 40–45 decibels, similar to a soft hum or quiet conversation. They’re generally quiet enough for home, travel, or public use.
Most models require minimal maintenance:
Wipe down the machine regularly
Clean or replace air filters as directed
Avoid water exposure and extreme temperatures
Store in a ventilated space
A high-quality unit can last 5–7 years or more with proper care. GOYOJO come with 3 year warranties, and replacement parts (like batteries and filters) are widely available.
Choosing a portable oxygen concentrator is a big step toward regaining freedom and improving quality of life. By understanding how these devices work and which features matter most, you can make a confident, informed choice that supports your health and lifestyle.
If you still have questions, reach out to your doctor or oxygen supplier—they can help you find the perfect match.
