An oxygen concentrator is essential equipment for patients who need supplemental oxygen at home due to conditions such as COPD, severe asthma, pulmonary fibrosis, heart failure, or recovery after serious illness. Unlike traditional oxygen cylinders, a concentrator draws in room air, filters out nitrogen using molecular sieve technology, and delivers a continuous supply of concentrated oxygen (typically 90–95% purity). This eliminates the need for repeated cylinder refills or exchanges and provides a more practical long-term solution for many households in Bangladesh.
This comprehensive guide explains how oxygen concentrators work, the differences between stationary and portable models, current price ranges in Bangladesh, key factors that influence cost, what to check before buying, running costs, and practical advice so you can choose the right device for your doctor’s prescription and daily needs.
How an Oxygen Concentrator Works
Room air contains about 21% oxygen and 78% nitrogen. Inside the concentrator, a compressor pushes air through zeolite molecular sieve beds that adsorb nitrogen. The remaining oxygen-enriched gas is delivered to the patient through a nasal cannula or mask at the prescribed flow rate (measured in litres per minute, or LPM).
Most home concentrators maintain oxygen purity of 90–95% at the rated flow. Performance can drop if filters are dirty, sieve beds are worn, or the unit is used above its designed capacity, so regular maintenance is important.
Stationary vs Portable Oxygen Concentrators
The right type depends on your prescribed flow rate, mobility needs, and how many hours per day you require oxygen.
Stationary (Home) Concentrators
- Designed for continuous use while plugged into a wall outlet
- Deliver continuous-flow oxygen (steady stream)
- Common capacities: 5 LPM or 10 LPM
- Heavier (usually 15–30+ kg) and intended to stay at home
- Can run 24 hours a day if needed
- Suitable for overnight use and higher flow requirements
- Generally more affordable for long-term home therapy
Portable Oxygen Concentrators (POCs)
- Lightweight and battery-powered for mobility
- Most use pulse-dose (demand) delivery — oxygen is released only when you inhale, which conserves battery
- Some higher-end models offer limited continuous flow
- Weigh typically 2–10 kg and can be carried or wheeled
- Ideal for going outside, travelling, or moving between rooms
- Battery life varies (often 2–8 hours depending on setting and battery size)
- Usually more expensive due to compact engineering and battery systems
Many patients benefit from a combination: a stationary unit for home and overnight use, plus a portable unit for outings. Always confirm with your doctor whether continuous flow or pulse dose is appropriate for your condition (especially during sleep).

- Premium international portable systems (e.g., certain Philips SimplyGo-type units) can reach ৳300,000 or higher when available
Rental options are widely available in Bangladesh (daily, weekly, or monthly packages), which can be a practical choice for short-term recovery or while deciding on a purchase.
Prices fluctuate with import costs, stock, and whether accessories (extra cannulas, filters, batteries, or carry bags) are included. Always confirm the exact model specifications and current pricing with the seller.
What Affects the Price of an Oxygen Concentrator?
- Maximum flow rate — 5 LPM units are the most common and affordable; 10 LPM models cost more and are used when higher flows or dual outlets are required.
- Delivery mode — Continuous-flow stationary units vs pulse-dose portables. Continuous flow generally costs less for equivalent capacity.
- Brand and build quality — Established brands (Philips, Longfian, Yuwell, Owgels, etc.) with proven reliability and local service command higher prices than lesser-known imports.
- Battery system (portables) — Longer runtime, extra batteries, and car chargers increase cost.
- Noise level — Quieter compressors (important for bedroom use) often cost more.
- Features — Dual flow outlets, nebulizer ports, oxygen purity displays, alarms, and remote monitoring add to the price.
- Warranty and after-sales support — Genuine units with local servicing and readily available spare parts (filters, sieve beds) are worth the premium in Bangladesh.
Key Factors to Check Before Buying
- Match the prescribed flow rate — Confirm the exact LPM required at rest and during activity with your doctor. An undersized machine will not meet clinical needs.
- Oxygen purity — Look for units that maintain ≥90% purity at the maximum rated flow.
- Noise level — Check decibel rating if the machine will run overnight in a bedroom (many good units operate around 40–50 dB).
- Power consumption — Important for electricity costs during continuous use.
- Filter and sieve bed maintenance — Ask about cleaning/replacement intervals and local availability of parts.
- Alarms and safety features — Low oxygen purity, power failure, and obstruction alarms are valuable.
- For portables — Real-world battery life at your prescribed setting, weight, carry options, and FAA/airline approval if you plan to fly.
- Local service network — Ensure filters, cannulas, and technical support are accessible in Dhaka or your city.
Running Costs and Maintenance
Beyond the purchase price, consider ongoing expenses:
- Electricity (stationary units run continuously for many patients)
- Replacement external filters (usually every few months)
- Internal sieve bed lifespan (can be several years depending on usage and model; replacement is a significant cost)
- Nasal cannulas and tubing (regular replacement for hygiene)
- For portables: battery degradation over time and possible replacement
Regular filter cleaning and proper placement (away from walls, curtains, or heat sources) help maintain performance and oxygen purity. Avoid using oil-based products near the device and keep the area well ventilated.
Stationary or Portable — Which Should You Choose?
| Need | Recommended Type | Reason |
|---|---|---|
| High continuous flow or overnight use | Stationary | Reliable continuous delivery and higher capacity |
| Mostly home-based, limited mobility | Stationary | Lower cost and simpler operation |
| Frequent outings or travel | Portable (or both) | Battery power and mobility |
| Power cuts common | Stationary + inverter or portable with battery | Continuity of supply |
| Higher prescribed flow (≥5–6 LPM) | Stationary (5L or 10L) | Portables often limited in continuous flow |
Many families start with a quality 5 L stationary concentrator and add a portable unit later if mobility becomes important.
Buying Tips for Bangladesh
- Obtain a clear prescription specifying the required flow rate and whether continuous or pulse dose is needed.
- Purchase from reputable medical equipment suppliers who provide genuine products, warranty cards, and after-sales support.
- Compare total package cost (machine + cannulas + filters + any batteries or carry case).
- Ask about demonstration, home delivery, and setup assistance.
- Verify warranty duration and what it covers (compressor, sieve beds, etc.).
- Consider rental first if the need is short-term (post-hospital recovery) or if you want to test a model.
- Check electricity backup options (IPS/inverter compatibility) for stationary units given power conditions in many areas.
