Oxliv Portable Oxygen Concentrator Review: Is It Worth Buying?

A bigger model number can catch your eye. But it tells you very little about how a device actually delivers oxygen. Two machines can look almost alike and still work in completely different ways. One might send oxygen in pulses. Another provides a steady stream. That difference matters a lot when you’re comparing models for your own use.

Then there’s the battery and the weight you end up carrying. A small device body only tells part of the story. Add a battery and a bag, and the real number changes.

This Oxliv Portable Oxygen Concentrator review helps you make sense of those details before you buy. We compare all five models and explain what their features mean in plain words.

You’ll see how the output settings differ and what comes with each package. By the end, you’ll have a clearer view of the range. You’ll also know the questions worth asking before you choose.

First, let’s look at what Oxliv offers. Our range covers several sizes and delivery modes for you to choose from. We have a device for every need, you just need to find the one that fits you the best.

What Is Oxliv?

At oxliv.com, we offer portable oxygen devices and related accessories for buyers in the USA. Our range includes five models. They run from a compact continuous-flow machine to a ten-level concentrator with three delivery modes.

Our products are made for general wellness and comfort. They don’t replace prescribed oxygen equipment or professional medical care.

Each machine has its own controls and power setup. Before you compare the models, it helps to know what those output figures mean.

Understand the Output

A few terms can really change how you compare oxygen machines. Delivery mode explains how oxygen leaves the device. Concentration describes the gas itself. These details matter far more than the model name alone.

Three Delivery Modes

Pulse flow delivers oxygen in bursts when the device detects a breath. Fixed-frequency delivery sends bursts at a set pace instead. Continuous flow runs without any breaks.

On our eight-level machine, Constant Flow means 17 bursts per minute. Continuous Flow is a separate mode. It provides an uninterrupted stream.

Settings Versus Liters

Adjustable oxygen settings don’t always show liters per minute. Pulse settings use device-specific output levels. So the same number on two machines can mean different deliveries.

Take “1–8L” as an example. It refers to eight settings, not eight liters per minute. Always compare the actual output and delivery mode together.

Purity Versus SpO2

Oxygen purity describes the oxygen share in the gas a device delivers. Blood oxygen saturation, or SpO2, is different. It refers to oxygen in your blood, and it’s what a pulse oximeter estimates.

A machine’s concentration figure won’t predict your blood oxygen level. Keep that distinction in mind as you compare the range.

Compare the Five Models

A good comparison should cover more than price. This table brings the main features together, so you can weigh output against portability. Match the delivery mode to your intended use before you settle on a battery package.

Pulse output and continuous output describe different delivery patterns. Don’t treat their volume figures as direct substitutes.

Battery life shifts with the setting you choose and the battery’s condition. The weight figures use different bases too. So include the battery when you compare complete carry setups.

The table gives you the main differences at a glance. Next, look at the controls and accessories that come with each model.

A Closer Model Review

Our five machines differ in how they deliver oxygen and how you carry them. Some focus on a small body. Others add more delivery choices. Here’s how those features play out beyond the comparison table.

1–3L: Compact and Simple

The 1–3L continuous-flow device has two-button controls and three output settings. Its body measures 140 × 108 × 67 mm. That makes it the smallest machine in our range.

This compact unit provides 30% ±2% oxygen concentration. Its 3 L/min flow setting is worth a note, though. It doesn’t make the device equivalent to one that delivers a higher oxygen concentration.

• Controls: Two buttons for three output levels.

• Air processing: Dust filter and built-in anion function.

• Power: Built-in battery, wall power and car charging support.

• Included items: Oxygen hose, adjustable carry bag and user manual.

The built-in battery means there’s no detachable battery box to swap. For longer plans, check your access to a compatible power source.

1–5L: Pulse With Backup

Our 5-level concentrator delivers a pulse when it detects a breath. If breath detection stops, Active mode steps in with timed backup pulses.

Six filtration layers process the incoming air before delivery. A molecular sieve separates nitrogen from the air to produce concentrated oxygen.

• Output control: Five adjustable levels.

• Device alerts: Warnings for issues like battery and temperature.

• Power options: Wall power, compatible car power and battery use.

• Included accessories: Two nasal cannulas, shoulder strap and five filter pieces.

Oxygen purity reaches up to 95%. That’s not a guaranteed 95% at every setting, though. Contact our team if you need concentration details for a particular output level.

1–7L: Breath-Triggered Delivery

The 1–7L pulse machine has a digital screen that shows the selected level and battery information. Breath detection triggers its pulse delivery. When no breath is detected, fixed-frequency backup takes over.

Its detachable battery lets you swap a depleted pack for a charged spare. The device body weighs about three pounds before you add that battery.

• Battery design: Removable 6,400mAh battery box.

• Charging time: About four hours.

• Body dimensions: 195 × 85 × 175 mm.

• Included items: Car charging cable, two oxygen tubes, backpack and case.

The seven-level device provides 85–90% oxygen concentration. That figure varies with the selected level and your breath frequency.

1–8L: More Delivery Choices

Our 8-level concentrator offers three delivery modes across eight settings. Levels 1–6 use pulse delivery. Level 7 sends fixed-frequency bursts. And Level 8 provides continuous flow.

The device holds 90% ±3% oxygen concentration across all eight settings and three modes. Its maximum continuous output is 2,000 mL/min, equal to 2 L/min.

• Fixed-frequency mode: 17 bursts per minute.

• Warm-up time: About three minutes.

• Power inputs: 100–240V AC and 12V DC.

• Package options: One or two detachable 18-cell batteries.

• Included extras: Shoulder strap, nasal cannula and five replacement filters.

A two-battery package extends your total use through a swap. But both batteries don’t run at once. And an extra battery won’t increase oxygen output.

1–10L: A Wider Setting Range

The 10-level device uses a different pulse scale from the eight-level model. Pulse output starts at 150 mL/min. It then rises in 150 mL/min steps through Level 8.

Level 9 provides fixed-frequency delivery. Level 10 provides continuous flow. The maximum continuous output is 2 L/min. So ten settings don’t mean ten litres per minute.

• Battery weight: The detachable battery adds about 1.1 lb.

• Combined weight: About 4.8 lb before the bag and accessories.

• Power use: Below 100W.

• Charging time: About four hours.

• Included accessories: Carry bag, wall adapter, car charger and replacement filter pads.

This ten-setting machine provides 90% ±6% oxygen concentration across its operating levels. Its removable 18-cell battery supports use away from a wall outlet.

Battery and Daily Use

Your choice also depends on how long you’ll be away from power. Battery capacity matters, of course. But the mode you select affects runtime too. So compare the complete setup, not just the device body.

Plan Your Battery Use

The eight-level concentrator has an 18-cell rechargeable battery. It provides up to 12 hours in pulse mode. Actual battery life varies with the setting you choose and the battery’s condition.

Always use a battery made for your exact machine. And follow the model’s instructions when you remove or replace one.

Check the Full Setup

Include the installed battery and carry bag when you weigh the load. Use our experts recommended buying checklist to review the battery, output, weight, and accessories before you buy. Add any spare battery you plan to take. Then check these details before you leave:

• Charge the battery with the correct AC power adapter.

• Check car charger compatibility.

• Learn the controls and screen messages.

• Keep the air vents clear as the manual directs.

These checks help you plan for time away from an outlet. Next, compare what comes in the package and what support is available.
