Top 5 LPM Oxygen Concentrators for Home Use in India (2026): Features Compared

A 5-litre oxygen concentrator helps people who need extra oxygen at home. These machines provide oxygen continuously, but different models may vary in oxygen purity, flow control, weight, power use, and extra features. 

In this guide, we compare four 5 LPM oxygen concentrators available in India: Oxysure Home 5L, Oxymed Mini, Philips Respironics EverFlo and DeVilbiss 5 LPM. We look at their important specifications and practical features to make the comparison easier for patients and caregivers.

What Actually Differs Between 5 LPM Oxygen Concentrators?

• Oxysure Home 5L offers live oxygen purity monitoring, 0.1 LPM flow adjustment, and single-switch operation for home use.
• Oxymed Mini offers a compact 13.9 kg design, in-built oxygen purity analyzer, digital display and built-in nebulizer.
• Philips EverFlo is a well-known home oxygen concentrator with a 0.5–5 LPM flow range and 93% ±3% oxygen concentration.
• DeVilbiss 5 LPM is a heavier stationary option with a 1–5 LPM flow range and 93% ±3% oxygen concentration.
• The right oxygen concentrator depends on the prescribed oxygen flow, monitoring features, noise, portability, power consumption, warranty and local service support.

• Oxysure, Philips Respironics, and Oxymed have strong service networks across India, with reasonably priced spare parts and clear after-sales support, without hidden or excessive service charges.

How We Compared These Oxygen Concentrators

All five oxygen concentrators were tested under the same conditions, running at 5 LPM for 24 hours a day over 6 days.

We compared:

• Oxygen purity across different flow settings
• Flow consistency
• Heat generation
• Alarm performance
• Overall operating stability

Oxygen purity was checked from 0.5 to 5 LPM using a calibrated third-party oxygen analyser.

We also tested 2 units of each model after at least 2,500 km of surface courier transportation to check whether shipping affected oxygen output or machine performance.
