Choosing the wrong oxygen concentrator isn’t just inconvenient—it can delay care, worsen symptoms, and create unnecessary stress for patients and caregivers. When oxygen is needed today, the decision usually comes down to 5-liter (5L) vs 10-liter (10L) concentrators.
Here’s how to make the right call—fast.
Why Oxygen Flow Rate Matters
Oxygen concentrators are measured by liters per minute (LPM). That number determines how much oxygen the machine can deliver continuously. If the flow is too low, oxygen saturation may not improve. If it’s too high, you may be overpaying or using equipment you don’t need.
The goal is the right level of support, immediately.
5L Oxygen Concentrators (Up to 5 LPM)

Best for moderate oxygen needs and short-term use.
Ideal if you or your patient:
- Has a prescription for 1–5 LPM
- Needs oxygen after a recent discharge
- Uses oxygen mainly at rest or overnight
- Requires a temporary or transitional setup
Why choose 5L:
- Smaller footprint
- Lower power usage
- Faster setup for standard needs
- Most commonly prescribed starting point
Common scenarios
Post-hospital recovery • COPD maintenance • Short-term respiratory support
10L Oxygen Concentrators (Up to 10 LPM)

Required for higher oxygen demand and advanced respiratory needs.
Ideal if you or your patient:
- Has a prescription for 6–10 LPM
- Desaturates during movement or activity
- Uses high-flow masks or specialty interfaces
- Has advanced conditions like severe COPD, pulmonary fibrosis, or CHF
Why choose 10L:
- Supports higher and more stable oxygen delivery
- Prevents under-delivery during exertion
- Often avoids urgent equipment upgrades later
Common scenarios
Advanced respiratory care • High-flow prescriptions • Long-term oxygen therapy
5L vs 10L — Quick Comparison
| Feature | 5L Concentrator | 10L Concentrator |
|---|---|---|
| Max Output | Up to 5 LPM | Up to 10 LPM |
| Typical Use | Moderate / short-term | High-demand / advanced |
| Size | Smaller | Larger, heavier |
| Power Needs | Lower | Higher |
| Upgrade Risk | May need later | Usually avoids re-delivery |

Oxygen Delivered When Waiting Isn’t an Option
Whether you need a 5L or 10L oxygen concentrator, the most important thing is getting the right support immediately. When care can’t wait, neither should your equipment.
