How to Choose an Oxygen Concentrator? A Complete Guide

In the Philippines, demand for oxygen concentrators has grown rapidly due to rising cases of chronic respiratory diseases, elderly care needs, and home-based recovery solutions. Families and caregivers are increasingly turning to oxygen concentrators as a safer and more cost-effective alternative to traditional oxygen tanks. However, choosing the right unit requires a clear understanding of oxygen concentrator selection criteria and the types of oxygen concentrators available in the market.

Home vs. Portable Oxygen Concentrators: The Key Difference

At a glance, the difference between home and portable units is clear:

• Home Oxygen Concentrators are designed for continuous oxygen therapy. They are larger, heavier, and ideal for patients requiring steady oxygen support 24/7.

• Portable Oxygen Concentrators are lightweight, battery-powered devices that support mobility and active lifestyles. They are perfect for patients who want to maintain independence while traveling, working, or doing daily activities.

When making your oxygen concentrator selection, knowing whether the user needs stationary support at home or mobility-friendly features is the first step.

Types of Oxygen Concentrators

There are two main types of oxygen concentrators classified by their oxygen delivery mode:

1. Continuous Flow Oxygen Concentrators

   • Deliver oxygen at a steady, preset rate.

   • Suitable for patients with higher and consistent oxygen requirements.

   • Common in home models like the VARON Serene 5 and VARON VH-2 Pro.

2. Pulse Flow Oxygen Concentrators (Pulse Dose)

   • Deliver oxygen only when the patient inhales, conserving power and oxygen.

   • Smaller, lighter, and more energy-efficient.

   • Found in portable models like VARON VL-2 and VP-6.

Some advanced units, like the VARON VP-2, offer dual modes (pulse + continuous) for flexibility.

Key Considerations in Oxygen Concentrator Selection

When comparing different types of oxygen concentrators, these factors should guide your choice:

1. Oxygen Flow Rate – Check if the device can provide the prescribed liters per minute (L/min). Home models often range from 1–7 L/min, while portable models range from 1–5 L/min.

2. Oxygen Concentration – Reliable medical-grade devices, such as VARON units, maintain 90%±3% concentration across most flow levels.

3. Portability & Size – Consider weight, battery life, and noise levels. For example, the VL-2 is lightweight and designed for easy mobility.

4. Continuous Use Capability – Home concentrators like the Serene 5 support 24/7 operation, while portable units run for hours depending on battery capacity.

5. Special Features – Intelligent alarms, nebulizer functions, LED/LCD displays, and filtration systems improve usability and safety.

Frequently Asked Questions (FAQ)

1. What is the difference between an oxygen concentrator and an oxygen tank?
Oxygen tanks store a fixed supply of oxygen that eventually runs out, while concentrators filter oxygen from the air and provide an unlimited supply as long as they are powered.

2. Which type of oxygen concentrator is best for home use?
For home use, continuous flow units like the VARON Serene 5 or VH-2 Pro are ideal because they deliver stable oxygen levels and can run 24/7.

3. Can portable oxygen concentrators be used during travel?
Yes. Lightweight units such as the VARON VL-2 or VP-2 are designed for mobility. They come with rechargeable batteries, car chargers, and travel-friendly bags, making them suitable for trips and daily activities.

4. How do I know the right oxygen flow rate for my needs?
The correct flow rate should always be prescribed by a doctor. Most types of oxygen concentrators allow adjustable settings, ranging from 1–8 L/min depending on the model.

5. Are VARON oxygen concentrators available in the Philippines?
Yes. VARON provides both home and portable models in the Philippines, offering reliable oxygen therapy solutions tailored to the needs of Filipino patients and caregivers.
