Oxlife Independence review: 3 LPM portable oxygen

3 min read By HHZ Editorial Next review

The Oxlife Independence is a 16.7 lb wheeled portable concentrator with continuous flow from 0.5 to 3 LPM and pulse settings from 0.5 to 6.0. It's rated for 24/7 use, works up to 13,123 ft and is FAA-approved. Battery life is short at continuous flow: 2.25 h at 2 LPM with two batteries, per the manual. It cost $3,195 at The CPAP Shop on 13 October 2026, with a 5-year warranty. It suits people who need continuous flow away from home. This review is based on documents, not hands-on testing.

How we reviewed this: HHZ didn’t test this concentrator hands-on. This review is written from the manufacturer’s user manual, spec sheet and product page, linked below, plus a U.S. retail price checked on 13 October 2026. We don’t report comfort, noise or reliability impressions we haven’t measured. Your prescriber decides whether a pulse-dose or continuous-flow device meets your needs.

Verdict

From the documents, the Independence fills a gap that lightweight pulse-only POCs don’t: real continuous flow up to 3 LPM, 24/7 duty, a high altitude rating and a 5-year warranty. The costs are weight and short battery life at continuous settings. Plan around the manual’s battery table, not the marketing numbers.

Frequently asked questions

Does the Oxlife Independence have continuous flow?
Yes. It offers continuous flow from 0.5 to 3.0 LPM in 0.5 LPM steps, plus pulse dose from 0.5 to 6.0 (8–96 mL per breath), per O2 Concepts' manual (800-1097 Rev C).
How heavy is the Oxlife Independence?
16.7 lb for the device; the cart kit (wheels and pull handle) adds 2.17 lb and each battery weighs 1.4 lb, per the manual. It's a wheeled unit, not a shoulder-carry POC.
How long does the Independence battery last?
The manual's table, for two batteries at 20 breaths per minute, lists 4.75 h at 0.5 LPM continuous, 2.25 h at 2 LPM continuous and 1.5 h at 3 LPM. In pulse mode it lists 5 h at 0.5 and 3.75 h at setting 2. O2 Concepts' spec sheet gives higher figures (5.75 h at pulse 2 and 2.5 h at 2 LPM).
Can it be used with CPAP?
O2 Concepts' product page says it's compatible for use with CPAP and BiPAP. The user manual we read doesn't describe CPAP use, so follow your prescriber's and provider's setup instructions.
What's the warranty?
Five years from shipment for a new unit, two years for refurbished or demo units, two years on sieve tubes and one year on standard accessories including batteries, per O2 Concepts' warranty statement. It's not transferable.
