Oxliv portable oxygen concentrators offer five portable formats with different output ranges. The collection includes the 1–3L, 1–5L, 1–7L, 1–8L, and 1–10L models. Each model uses electrical power to process air around the device.

Weight, output type, and battery details differ across the range. A product name alone does not explain those differences. The tables and reviews below put every model beside the same practical details.

Product pages show the current option, price, and package details. Read those details before selecting a battery bundle.

Compare the Five Models

At 1.1 pounds, the 1-3L has the lowest weight and noise figure. Five settings and six filtration layers define the 1-5L. Seven settings and a removable battery distinguish the 1-7L.

The 1-8L has eight settings and three delivery modes. The 1-10L expands the range to ten settings. Each model has a different strength. No single specification should decide the purchase alone.

Controls and Readouts

A 2-button layout controls the three 1-3L outflow settings. Digital displays appear on the 1-5L, 1-7L, 1-8L, and 1-10L.

Those screens show the selected level and battery status.

A display does not replace the written manual. The manual identifies each button and screen message. Product alerts and control steps can differ between models.

What Comes With Each Model

Accessories affect how a device travels, charges, and stores between uses. The box contents also differ across the five models. Review the selected product page before payment because bundle options can change battery quantity.

The packages include different charging, carrying, tubing, and replacement accessories depending on the model. The table identifies the supplied items named for each model.

Model Included accessories
1-3L Carry bag, wall charger, car charger, nasal cannulas, and a user manual.
1-5L Wall power adapter, car charging cable, two nasal cannulas, travel carry bag, adjustable shoulder strap, five filter cotton pieces, and user manual.

1-10L Carry bag, shoulder strap, one or two rechargeable batteries, AC power adapter, car charger cable, nasal cannula, and five replacement filters.

Battery count for the 1-8L and 1-10L depends on the chosen option. Two nasal cannulas come with the 1-5L. A backpack and separate case come with the 1-7L.

Keep the manual with the product and charger. It explains the correct setup for that device. Only use accessories that match the exact product model.

How Portable Concentrators Process Air

The 1-5L, 1-7L, 1-8L, and 1-10L use internal air-processing components. An intake filter removes dust before the air reaches oxygen-separation parts. A molecular sieve separates oxygen from other gases in applicable models.

The 1-3L uses a filter and anion function. Its operating system differs from the larger models. Each device must have open vents for air intake and heat release.

A nasal cannula connects the device outlet to the user. Tubing should remain free from tight bends and visible damage. The manual provides the correct tubing connection steps.

Using the Models in Different Places

Each model can run from a wall connection. The 1-5L, 1-7L, 1-8L, and 1-10L also support compatible car power. Battery power allows use away from a connected outlet.

For short carry periods, the 1-3L has the smallest body. Among larger models, the 1-5L lists lower operating noise.

A compact device body and removable battery distinguish the 1-7L.

The 1-8L and 1-10L list up to 12 hours of battery runtime under stated conditions. The 1-8L also lists operation at elevations up to 5,000 meters. Airline acceptance remains a separate issue for every portable concentrator.

Airline rules can apply to device labels and battery arrangements. Contact the carrier before booking with any portable oxygen product. Bring the current product details if the airline requests them.

What to Compare Before Buying

Start with the details that affect the intended use. Battery time, carry weight, and power sources shape where a unit can go. Delivery mode describes a separate part of the choice.

  • Output details: Compare each model’s listed range and delivery pattern.
  • Purity figure: Read the stated percentage beside the selected model.
  • Battery setup: Confirm the battery size and bundle quantity.
  • Carry weight: Include the installed battery when comparing models.
  • Power source: Review wall, vehicle, and battery compatibility.
  • Box contents: Confirm the supplied bag, charger, filters, and tubing.

Low weight may be the main priority for a 1-3L buyer. A higher listed purity figure distinguishes the 1-5L.

Seven settings in a compact body distinguish the 1-7L. The 1-8L adds continuous flow at Level 8, while the 1-10L expands the range to ten settings and continuous flow at Level 10.

A long listed runtime may affect the choice. The final selection should match the buyer’s product requirements, preferred delivery mode, power needs, and daily routine.

Getting Started With a New Unit

The instruction manual should be read before the first use. It identifies the correct power connection and device controls. A charged battery gives the clearest runtime reference during early use.

Place the device on a firm and level surface. Keep enough room around the housing for ventilation. Remove the carry bag before operating the unit.

  • Power connection: Use the charger supplied for that model.
  • Tubing: Inspect the cannula and tubing before attachment.
  • Vents: Keep the intake and exhaust openings uncovered.
  • Control panel: Select the setting described in the manual.
  • Battery level: Charge before leaving a power source.

Start with a short test period in a familiar location. Listen for unusual sounds and read any screen message. The manual explains the normal startup process for each model.

A device alert should receive the response named in the manual. Do not increase a setting to address a fault. Contact support if the problem continues.

Safety Steps for Every Model

Oxygen can make nearby materials burn more readily. Smoke, candles, stoves, and other ignition sources should remain away from oxygen equipment. A wall outlet and cable must remain dry.

The device should remain stable during operation. Tubing should not cross a path where someone may trip. Keep the product away from direct heat and water.

  • No flames: Keep smoking, candles, and open flames away.
  • No covered vents: Leave every intake and exhaust area open.
  • Dry equipment: Keep electrical ports and adapters away from liquids.
  • Safe tubing: Route tubing away from walking areas.
  • Correct charger: Use the charger supplied for the selected model.

The same basic precautions apply to all five models. Product-specific warnings appear in each manual. A warning icon or alarm deserves attention before further use.

Do not store the device inside a hot vehicle. Avoid placing it near a heater or stove. A dry, stable location protects the device and its accessories.

Care Between Uses

Care tasks cover batteries, vents, filters, and tubing. The manual identifies which filter parts can be cleaned. Some filter pieces require replacement instead of washing.

Look at the tubing before each use. Replace tubing that has splits, stiffness, or loose connections. Keep cleaning liquid away from the electrical ports.

  • Filter care: Follow the manual’s cleaning or replacement schedule.
  • Vent care: Remove dust from air openings as instructed.
  • Tubing care: Replace damaged cannulas and tubing.
  • Battery care: Recharge after portable use when appropriate.
  • Storage: Keep the unit and accessories in a cool, dry place.

Model-specific care applies to the 1-3L filter and anion function. Filter cotton for the 1-5L should match its housing.

Five replacement filters come with the 1-8L and 1-10L packages. Repeated alerts can indicate a fault or blocked airflow. Support can review the model and alert description.

Do not open internal components unless the manufacturer instructs it.
