Oxygen Concentrator vs Oxygen Cylinder: Which Is Better?
When a family starts researching home oxygen therapy, one of the first questions that comes up is: oxygen concentrator or oxygen cylinder — which one should we get? The honest answer is that neither option is universally “better.” Which one fits your situation depends on the patient’s prescribed oxygen flow, how long therapy is needed, how reliable your electricity supply is, portability needs, and whether you need backup for emergencies.
This guide compares how each device actually works, what they cost, and where each one tends to make more sense — so you can have an informed conversation with your doctor and supplier rather than guessing.
How They Work
Oxygen Concentrator: draws in room air, separates out the nitrogen, and delivers the remaining concentrated oxygen to the patient continuously, as long as it has power.
Oxygen Cylinder: stores a fixed supply of already-compressed medical oxygen, which is delivered to the patient through a regulator and flow meter until the stored gas runs out.
In short, a concentrator produces oxygen on demand from the air around it, while a cylinder stores a limited quantity of oxygen that needs to be refilled or replaced once used up.
Portability
Oxygen Cylinder:
- Portable/mini cylinder options are available
- Standard cylinders can be fairly heavy
- A trolley is often needed to move them safely
- Transport and storage safety matter (see our oxygen cylinder safety guide for details)
Oxygen Concentrator:
- Standard home models usually come with wheels, making room-to-room movement relatively easy
- Battery-powered portable models also exist for travel or outings
- Portable concentrator models are generally more expensive than standard home units
Important: “portable” doesn’t mean the same thing for both devices. A standard home concentrator and a dedicated portable oxygen concentrator have quite different mobility, and the same is true for a standard versus a mini oxygen cylinder — don’t assume equivalent portability just because both are labeled “portable.”
Electricity Requirement
Oxygen Concentrator: requires electricity to operate. If the power goes out, the machine stops producing oxygen. Given how common load-shedding can be in parts of Bangladesh, it’s worth considering backup power (like an IPS or generator) and/or a backup oxygen cylinder alongside a concentrator.
Oxygen Cylinder: doesn’t require electricity at all. This is exactly why a cylinder is often kept as backup for emergencies or power outages, even by households that primarily use a concentrator.
Storage
Concentrator:
- Keep it in a dry, clean area
- Ensure adequate ventilation around the machine
- Don’t block the air inlet or outlet
- Protect it appropriately from heat and moisture
Cylinder:
- Keep it upright
- Secure it properly
- Keep it away from heat and fire
- No smoking nearby
- Keep it away from oil and grease
- Ensure adequate ventilation
- Protect the valve

Emergency Backup
This is one of the most important parts of the comparison. A concentrator’s key limitation is that it stops working without electricity — so in a power outage, it offers no oxygen supply on its own. A cylinder’s key advantage is that it can deliver oxygen without any electricity at all.
For this reason, many long-term home oxygen setups use a primary source plus a backup source — for example, a concentrator for daily use and a cylinder kept ready for outages or emergencies. That said, this isn’t automatically the right setup for every patient; whether a backup is medically necessary, and what kind, should be discussed with the patient’s doctor or care provider.
Long-Term Use
Concentrator, for long-term continuous therapy:
- Higher initial cost
- No refills needed
- Requires electricity
- Requires maintenance
- Power backup needs to be considered
Cylinder, for long-term use:
- Comparatively lower initial cost
- Refills needed repeatedly
- Delivery/refill logistics to manage
- May need multiple cylinders on hand
- Regulator and accessories required
Cost Consideration
Rather than asking simply “which is cheaper,” it helps to think in terms of total cost of use:
Oxygen Concentrator = Purchase/Rental + Electricity + Maintenance
Oxygen Cylinder = Purchase/Rental + Refills + Delivery + Accessories
How this plays out depends on your situation:
- A few days: consider rental cost for either device
- A few weeks: compare rental vs. purchase for your expected duration
- Several months or years: compare the full total operating cost, not just the upfront price
- Frequent power cuts: factor in the cost of backup power or a backup cylinder
- Emergency use: a ready-to-use cylinder has an advantage since it needs no power
- Continuous prescribed therapy: discuss concentrator suitability directly with your doctor or provider, since flow requirements and duration matter most here

| Best-suited for | Worth considering for long-term/home use | Worth considering for backup, emergency, or short-term use |
There’s intentionally no single “winner” in this table — the right choice depends on the patient’s prescribed flow, therapy duration, electricity reliability, mobility needs, and emergency requirements, which vary from one household to another.
Which One Is Right for You?
A few starting points, not hard rules:
- If oxygen is needed continuously for months or years, and electricity supply is reasonably reliable, a concentrator is often worth discussing with your doctor.
- If oxygen is needed only occasionally, for a short recovery period, or specifically as backup, a cylinder — bought or rented — is often the more practical starting point.
- If both continuous use and power reliability are concerns, many households use both: a concentrator as the primary source and a cylinder as backup.
None of this replaces medical advice — the prescribed flow rate and the choice of device should always be confirmed with the patient’s doctor or healthcare provider.

Frequently Asked Questions
1. What is the difference between an oxygen concentrator and an oxygen cylinder? A concentrator produces oxygen continuously from room air using electricity, while a cylinder stores a fixed, refillable supply of compressed medical oxygen that doesn’t need power.
2. Does an oxygen concentrator need electricity? Yes, a concentrator requires electricity to operate, and it stops producing oxygen if the power goes out.
3. Does an oxygen cylinder need electricity? No, a cylinder delivers oxygen without any electricity, which is why it’s often used as backup during power outages.
4. What happens to an oxygen concentrator during load shedding? It stops producing oxygen unless it has a battery backup or is connected to backup power such as an IPS or generator — this is why many households also keep a backup cylinder.
5. Which is better for long-term oxygen therapy? It depends on the patient’s needs — concentrators avoid recurring refills but need reliable electricity and maintenance, while cylinders need repeat refills but work independent of power. Discuss the right fit with your doctor.
6. Which is better for emergency oxygen? A cylinder is generally more practical for emergencies since it doesn’t depend on electricity and can be used immediately.
7. How portable is an oxygen concentrator? Standard home models typically have wheels for room-to-room movement, while dedicated portable, battery-powered models exist for travel — these are usually more expensive than standard units.
8. How portable is an oxygen cylinder? Standard cylinders are fairly heavy and usually need a trolley, though smaller portable/mini cylinders are also available.
9. How much does an oxygen concentrator cost in Bangladesh? Currently roughly ৳35,000 to ৳1,00,000+ depending on model and capacity, with many 5L models around ৳35,000–৳55,000. Prices can change, so confirm before ordering.
10. How much does an oxygen cylinder cost in Bangladesh? Currently around ৳8,000 for China, ৳9,000 for Islam, and ৳16,000 for Linde/BOC, with refills starting around ৳800. Prices can change, so confirm before ordering.
11. Should I keep a backup oxygen cylinder if I already have a concentrator? Many households do, specifically to cover power outages or emergencies, but whether this is necessary for a specific patient should be discussed with their doctor.
12. Can an oxygen concentrator replace an oxygen cylinder, or vice versa? They serve different roles rather than being direct substitutes — a concentrator suits continuous long-term use where power is reliable, while a cylinder suits short-term, emergency, or backup use. Many patients benefit from having access to both.
13. Where can I buy or rent an oxygen concentrator or cylinder in Dhaka? Medical Product BD supplies both, with sales, rental, refill, and home delivery options across Dhaka — call 01811122698 to confirm current models, stock, and pricing.
