If you are planning to buy an oxygen concentrator online, the most important thing is to choose a machine that matches the prescribed oxygen requirement and your intended use. Price matters, but it should not be the only deciding factor.
An oxygen concentrator is a medical device that takes in room air, separates oxygen from other gases, and delivers concentrated oxygen through a delivery system. Depending on the model, concentrators can offer different flow rates, oxygen concentration levels, sizes, power requirements and delivery methods.
Greenwell Healthcare provides oxygen concentrators from brands including Philips, Oxymed, Evox, Yuwell, Inogen and Devilbiss, with product information and technical support for customers looking for home oxygen equipment.
What Is an Oxygen Concentrator?
An oxygen concentrator is a medical device designed to provide concentrated oxygen from surrounding air.
Unlike an oxygen cylinder, a concentrator does not require routine cylinder refilling. It operates using an appropriate electrical power source and delivers oxygen through equipment such as a nasal cannula, depending on the model and prescribed therapy.
Oxygen concentrators are available in different configurations, including:
- Stationary oxygen concentrators
- Portable oxygen concentrators
- Continuous-flow oxygen concentrators
- Pulse-dose oxygen concentrators
- Higher-flow oxygen concentrators
The correct type depends on the user’s prescribed oxygen therapy and practical requirements.
Why Buy an Oxygen Concentrator Online?
Buying an oxygen concentrator online can make it easier to compare products, specifications and available support before making a purchase.
However, medical equipment should not be selected only because an online listing has a low price.
Before placing an order, compare:
- Oxygen flow rate
- Oxygen concentration
- Continuous or pulse-dose delivery
- Device weight and dimensions
- Power consumption
- Noise level
- Safety indicators and alarms
- Warranty
- Service availability
- Replacement parts and accessories
- Delivery and return policies
For home medical devices, the FDA also highlights the importance of considering the home environment, electrical safety, fire hazards and other practical risks.
How to Choose an Oxygen Concentrator Online
Choosing the right oxygen concentrator becomes easier when you compare the important specifications rather than focusing only on price.
1. Check the Prescribed Oxygen Flow Rate
Flow rate is one of the first specifications you should check before buying an oxygen concentrator.
It is usually expressed in litres per minute (LPM).
Common home oxygen concentrator categories include 5 LPM and higher-flow machines. Greenwell Healthcare, for example, lists several 5 LPM models, including Philips EverFlo, Evox 5 LPM, Oxymed Mini 5 LPM and Yuwell 7F-5.
However, do not select the flow rate based only on the maximum capacity of the machine.
If oxygen therapy has been prescribed, follow the healthcare professional’s instructions for the required flow and duration.
2. Understand Continuous Flow vs Pulse Dose
Oxygen concentrators can use different oxygen-delivery methods.
Continuous Flow
A continuous-flow oxygen concentrator provides oxygen continuously at the selected flow setting.
This type is commonly used for home oxygen therapy when continuous oxygen delivery has been prescribed.
Pulse Dose
A pulse-dose device delivers oxygen in response to inhalation.
This delivery method is often found in portable oxygen concentrators, but suitability depends on the user’s prescribed therapy and the specific device.
Do not choose pulse dose simply because the machine is smaller or more portable.
The delivery method should be appropriate for the prescribed oxygen therapy.
3. Compare Oxygen Purity
Oxygen concentration is another important specification when you compare oxygen concentrators online.
For example, Greenwell lists the Evox 5 LPM with a stated oxygen purity of 90–96%, while the Philips EverFlo page lists approximately 93 ± 3% oxygen concentration at 5 LPM.
Specifications can vary by model and operating conditions, so always check the manufacturer’s product documentation for the exact model you are considering.
4. Choose Between Stationary and Portable Oxygen Concentrators
Your intended use can help determine which type is appropriate.
Stationary Oxygen Concentrator
A stationary oxygen concentrator is designed primarily for home use.
It may be suitable when:
- The device will remain mainly at home
- Long-duration use is required
- Portability is not the primary requirement
- Continuous-flow oxygen has been prescribed
Portable Oxygen Concentrator
A portable oxygen concentrator is designed with mobility in mind.
When comparing portable models, check:
- Device weight
- Battery capacity
- Battery charging options
- Delivery method
- Flow settings
- AC/DC power options
- Operating time
Remember that portable does not automatically mean suitable for every oxygen-therapy requirement.
5. Check Power Consumption
An oxygen concentrator needs electricity to operate.
Power consumption becomes particularly relevant when the machine will be used for several hours each day.
Before you buy, check:
- Wattage
- Required voltage
- Power-source compatibility
- Backup power requirements
- Manufacturer operating instructions
For example, Greenwell lists the Philips EverFlo at approximately 350 W average power consumption and the Evox 5 LPM at approximately 350 W.
Actual requirements can vary by model and operating conditions, so use the manufacturer’s specifications for the final comparison.
6. Consider Noise Level
If an oxygen concentrator will operate in a bedroom or other quiet area, noise can be an important comfort consideration.
7. Look for Useful Safety Features
Safety features can differ between oxygen concentrator models.
Depending on the model, you may find:
- Power-failure alarms
- Oxygen-purity indicators
- System alerts
- Overheating protection
- Self-diagnostic systems
- Operating indicators
For example, Greenwell lists a power-loss alarm for the Evox 5 LPM and multiple safety alarms/self-diagnostic features for the Yuwell 7F-5.
Always read the product manual and follow the manufacturer’s safety instructions.
Oxygen also increases fire risk, so keep oxygen equipment away from smoking, flames and other ignition sources. The FDA specifically identifies fire hazards as an important consideration for home oxygen therapy.
Oxygen Concentrator Price in India
The price of an oxygen concentrator can vary considerably depending on:
- Flow capacity
- Stationary or portable design
- Brand
- Oxygen concentration specifications
- Battery features
- Display and monitoring features
- Warranty
- Service support
- Accessories
Greenwell Healthcare currently publishes an oxygen-concentrator price guide covering different categories and models. Because medical-device prices can change, buyers should check the current product page or contact Greenwell for the latest price rather than relying on an outdated article figure.
What Should You Compare Besides Price?
A lower purchase price does not necessarily mean lower overall cost.
Compare:
Purchase price + warranty + service + replacement parts + accessories + power requirements
This gives you a more realistic picture of the value of the equipment over its intended period of use.
