Best 5 Litre Home Oxygen Concentrators in India (2026)

A 5-litre oxygen concentrator is commonly used at home when continuous supplemental oxygen is required. Choosing the right device involves more than just oxygen flow rate and price.

In this guide, we compare five 5-litre oxygen concentrators based on key factors such as oxygen purity, flow consistency, noise, power consumption, weight, alarm features, and suitability for long-term home use.

Key Takeaways

• Oxymed Inteli 5 LPM delivered 95.6% purity at 1 LPM, with oxygen purity remaining above 92% even at the maximum 5 LPM flow.
• Oxysure Home 5 L maintained 93%±3% oxygen purity from 1 to 5 LPM, demonstrating stable oxygen output across different flow settings.
• Philips Oxygenate 5 offers a 93%±3% oxygen purity range, providing oxygen output across its 1–5 LPM operating range.
• DeVilbiss 525KS recorded 93%±3% oxygen purity across 1–5 LPM, showing consistent performance throughout the tested flow range.
• Oxysure Home 5 L provides an upfront oxygen purity display, allowing the reading to be monitored while the machine is running.
• Philips Oxygenate 5 also provides a 24×7 oxygen purity display, making continuous monitoring convenient.
• Philips Oxygenate 5 allows 0.1 LPM flow increments, offering finer control over oxygen flow compared with models that use larger increments.
• Oxysure Home 5 L combines consistent oxygen purity with features designed for convenient home use, including single-switch operation, an inbuilt humidifier, and a 20-layer filtration system.

How Were These Oxygen Concentrators Tested?

The oxygen concentrators were subjected to a 24×7 running test. Each machine was operated continuously for 8 days at a flow rate of 5 LPM.

During continuous operation, the machines were checked for :

• Overheating
• System failure
• Oxygen purity
• Flow consistency

The machines were operated under Indian environmental conditions.

Oxygen Purity Test

Oxygen purity was checked at flow rates ranging from 0.5 to 5 LPM. Only the machines that maintained an oxygen purity of 93%±3% passed this test.

Courier Transit Test

The oxygen concentrators were also subjected to a courier transit test covering a minimum distance of 3,000 km by surface transport. The test used Delhivery and Blue Dart to assess how the machines handled long-distance transportation.

Alarm Testing

The alarm systems were checked to confirm whether the manufacturer-declared alarms activated at their stated thresholds.

The following alarms were checked:

• Low oxygen purity alarm: Trigerred when purity drops below therapeutic level (82%)

• High-temperature alarm

• Power-failure alarm

• Flow-obstruction alarm

The time taken for an alarm to activate after introducing the relevant fault was also recorded.

Flow Output Verification

The actual flow output of the oxygen concentrators was verified using a third-party analyser.

The testing was conducted using a sample size of three units for each model.

Quick Comparison of 5 liter Oxygen Concentrators

1. Oxymed Inteli 5LPM

The Inteli is an advanced version of the Oxymed Mini. The brand gained its popularity  because it was the first brand product to have an oxygen purity display, making it easier to check the oxygen purity level while the machine is running.

Pros

• It uses a DC compressor, which consumes less power, with power consumption of around 160 W.
• It comes with coverage for 3 years (upto 15,000 hours).
• It can automatically adjust the oxygen flow based on SpO₂.
• It uses 100% Lithium sieve beds.
• It weighs approximately 15.5 kg.
• It has an oxygen purity display, patients can view oxygen purity by pressing combination of buttons.

Cons

• The DC compressor works at variable speeds, so the noise level can change during operation.
• After a power cut, the machine restarts at 3 LPM instead of remembering the previous flow setting.
• It does not have single-switch operation, which means multiple controls may be required to start and operate the machine.
• It does not come with a floating-ball flowmeter because it is considered to be gold standard.
• The flow starts at 1 LPM and increases in 1 LPM steps. Pulmonologists prefer smaller increments, such as 0.1 LPM or at least 0.5 LPM, for better flow control, especially for paediatric patients.
• A combination of buttons needs to be pressed to view the oxygen purity reading, unlike the Oxysure Home 5 L and Philips Oxygenate 5, which display the reading upfront on the screen without pressing any buttons.

2. Oxysure Home 5 L

It is designed with features that make oxygen monitoring and operation simple, along with filtration designed for high-dust conditions.

Pros

• It has a 24×7 live oxygen purity display and oxygen purity indicator, making it easy to monitor oxygen purity while the machine is running.
• The machine has excellent build quality.
• It uses single-switch operation, making it easy to access and operate.
• It comes with a gold-standard floating-ball flowmeter, which is highly preferred by healthcare professionals across the world.
• It has an inbuilt humidifier.
• It has an excellent service network across India.
• It uses a 20-layer filtration system, designed for high-dust conditions in India and the UAE.
• At around 13.9 kg, it is an ultra-lightweight oxygen concentrator.

Cons

• The nebuliser port is placed at the bottom of the machine on the rear side, so access to it could be better.
• It does not have a wheel lock.
• The display cannot be turned off.
