How to Choose the Right Portable Oxygen Concentrator
Oxygen Delivery Method: Pulse vs. Continuous
Pulse Delivery: Delivers oxygen when you inhale. Uses less battery, smaller units, lighter weight. Works for most active users. Includes Inogen One G5, SeQual Eclipse 5, ResMed Portable O2.
Continuous Flow: Provides constant oxygen regardless of inhalation. Better for higher oxygen needs. Requires more power, heavier units. Includes Philips SimplyGo Mini, Caire AirSep Focus (hybrid).
Critical Factors to Consider
- Weight: If traveling or running errands, prioritize models under 3 lbs. Daily mobility improves dramatically with lighter units.
- Battery Life: Calculate daily needs. If you're out 8+ hours, you'll need 6+ hour battery or backup batteries.
- Oxygen Output (LPM): Your physician prescribes this. Ensure the unit covers your prescribed range (typically 1-3 LPM for mild cases, 4-6 for moderate).
- Noise Level: Most quality units run 30-45dB (quiet enough for conversation). Essential for work/social settings.
- FAA Approval: All reviewed models are FAA-approved for air travel. Essential if you fly.
