Buying Guide for Oxygen Concentrators

An oxygen concentrator is a medical device that delivers oxygen-enriched air to patients with respiratory conditions. Unlike oxygen cylinders, it filters and concentrates oxygen from the surrounding air, providing a continuous supply.

Key Factors to Consider Before Buying

-  Flow Rate
Choose a model with a flow rate suitable for your prescribed oxygen requirement. Most concentrators offer between 1–5 LPM (liters per minute), while high-flow models can go up to 10 LPM.

-  Continuous vs. Pulse Flow

  • Continuous Flow: Provides a constant oxygen supply, ideal for severe cases.

  • Pulse Flow: Delivers oxygen on inhalation  better for portable use.

-  Portability
Consider whether you need a stationary unit for home use or a lightweight portable model for outdoor use and travel.

-  Power Source & Battery Life
Check for models with both AC and DC power options, and for portable units, battery backup is essential.

-  Noise Level
Some units operate more quietly than others  especially important if used overnight.

-  Maintenance & Warranty
Look for a device with low maintenance, reliable after-sales service, and a good warranty period.
