My Dad's Oxygen
Jeff, Thank you again for helping in getting the portable oxygen for my father’s needs. He absolutely LOVES the new equipment and the portability now, which has allowed him so much more freedom of activity! I appreciate your help, especially since it was a weekend. So grateful.

Great experience!
Jeff is a blessing. I wasn't aware, after my purchase, that my needs were so different. I'm a neck breather. He went above and beyond to make sure my purchase was exactly as needed. HE took the initiative to contact my Dr to find out exactly what my needs were. With today's challenges, he nailed it. I WILL DEFINITELY recommend Jeff and his company for all your needs with oxygen. He's giving me independence again. He could have just concentrated on a sale. Nope, he wanted everything to be right,instead of just a sale.Jeff, you rock !! Thank you for all your help.

Great Company!
We had been looking at portable oxygen for my husband for quite some time. He had the small green canisters but wanted something lighter and more aesthetically pleasing. I came upon Inspired Oxygen and made an inquiry. Todd, the owner, called us that night and introduced himself, the company and the product. It seems like all we had to do was sign for the UPS delivery and take the product out of the box. Great company to handle your needs and I would recommend them without hesitation.

The Oxlife Liberty 2 portable oxygen concentrator is built for people who need a true “all-day, all-settings” solution.
It’s one of the few portable systems that combines continuous flow and high-capacity pulse dose in a wearable design —
so you can stay mobile without giving up the oxygen delivery you rely on.

With continuous flow up to 2.0 LPM and pulse flow settings 1–10, the Liberty 2 is a strong choice for users who want a
single device that can support home use, travel, and everyday life with fewer compromises. :contentReference[oaicite:1]{index=1}

Why the Liberty 2 Is a Standout Portable Oxygen System

The Liberty 2 is designed for flexibility. Many portable oxygen concentrators are pulse-only.
The Liberty 2 gives you the freedom of portability while also offering continuous flow options when needed.

Key advantages:

  • Continuous flow settings up to 2.0 LPM (portable, wearable format)
  • Pulse flow settings 1–10 for higher pulse dose capability
  • Designed for 24/7 use as a portable + stationary solution
  • FDA cleared / medical-grade and FAA compliant for travel
  • Made in the USA

True Continuous Flow Portability (Up to 2.0 LPM)

The Liberty 2 is best known for delivering continuous flow oxygen up to 2.0 LPM while still being a portable, wearable system —
a major benefit for users who prefer or require continuous flow for certain situations. :contentReference[oaicite:2]{index=2}

Note: exact settings and usage should always match your prescription and clinician guidance.

High Pulse Dose Capacity (Settings 1–10)

In addition to continuous flow, the Liberty 2 offers pulse settings 1 through 10, giving you flexibility across a wider range of needs
— all in one device. :contentReference[oaicite:3]{index=3}

Battery Life and Daily Use

Battery runtime varies by mode and setting. Many users like the Liberty 2 because it supports both continuous and pulse delivery in one platform,
reducing the need to switch devices for different situations.

Typical continuous-flow runtimes (varies by setting):

  • 0.5 LPM: ~3.25 hours
  • 1.0 LPM: ~2 hours
  • 1.5 LPM: ~1.5 hours
  • 2.0 LPM: ~1 hour

These are commonly published estimates; real-world results vary by battery health, altitude, temperature, and usage. :contentReference[oaicite:4]{index=4}

Who the Liberty 2 Is Best For

This system is a great fit if you:

  • Want continuous flow in a portable wearable device
  • Also want higher-range pulse dose settings (1–10)
  • Need one device for home routines + getting out of the house
  • Travel and want an FAA-compliant option
  • Prefer a durable, single-source solution

Warranty & Peace of Mind

The Liberty 2 is commonly sold with a 3-year manufacturer warranty (confirm current coverage at time of purchase).
We carry new units only — no refurbished or used equipment. :contentReference[oaicite:5]{index=5}

Pricing & Personalized Configuration

Because battery and accessory configurations can vary, pricing depends on how you’ll use the system day to day.
Rather than pushing a generic package, we help you:

  • Confirm the correct mode (continuous vs pulse) for your routine
  • Match batteries and accessories to your typical day
  • Make sure your prescription and lifestyle align with the right settings
