It delivers pulse-dose oxygen across five settings — up to 1,050 mL per minute at setting 5 — with UltraSense breath detection and an autoDOSE safety feature that keeps oxygen flowing even if a breath isn't detected. Simple one-touch operation, a full-color LCD, and a glow-in-the-dark keypad make it easy to use day or night.\u003c\/p\u003e\n  \u003cp\u003eBuilt for an active, on-the-go lifestyle, it's FAA-approved for commercial air travel, runs and recharges on AC (wall) or DC (car) power, and uses user-replaceable batteries that snap onto the bottom of the unit. Choose the configuration that fits how far you roam: the standard 8-cell battery for the lightest everyday carry, two 8-cell batteries for hot-swapping on longer days, or the larger 16-cell battery for the most runtime from a single pack.

If a steady continuous flow is required (for example, for some overnight needs), a continuous-capable unit like the SeQual Eclipse is the better fit. Beyond that, the only real decision is the battery: the single 8-cell is the lightest everyday option, two 8-cell batteries let you carry a charged spare and hot-swap for a full day out, and the 16-cell gives the longest runtime from one pack for just about a pound more. All three are the same concentrator, so choose based on how long you're typically away from an outlet.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n  \u003cul class=\"enhdme-spec-list\"\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eType\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003ePortable oxygen concentrator\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBrand\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eCAIRE FreeStyle Comfort\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eDelivery Mode\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003ePulse dose (settings 1–5)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eMax Output\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eUp to 1,050 mL\/min (setting 5)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eOxygen Purity\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eUp to 95%\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBreath Detection\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eUltraSense + autoDOSE\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eWeight\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e~5 lbs (8-cell) \/ ~6 lbs (16-cell)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eDimensions\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e10.0\"H (8-cell) \/ 11.0\"H (16-cell) x 7.3\"W x 3.1\"D\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eSound Level\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e~40 dBA at setting 2\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003ePower\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eAC 100–240V; DC 11–18V; battery\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eStartup\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eUnder 2 minutes\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eAir Travel\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eFAA-approved\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eIncludes\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eConcentrator, battery, carry bag + strap, AC\/DC power supplies, manual\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eWarranty\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e3-year (unit + sieve), 1-year battery\u003c\/span\u003e\n\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cdiv class=\"enhdme-faq-section\"\u003e\n    \u003cdiv class=\"enhdme-faq-item\"\u003e\n      \u003cp\u003e\u003cstrong\u003eDoes it have a continuous flow setting?\u003c\/strong\u003e\u003c\/p\u003e\n      \u003cp\u003eNo — the FreeStyle Comfort is a pulse-dose concentrator.
