Among the various oxygen concentrator sizes sold in India, the 5-litre model has become something of a default choice for home care, and for good reason. It sits at the sweet spot between capacity and affordability, making it suitable for the majority of patients recovering from respiratory illness or managing a chronic condition like COPD at home. If you're trying to understand what a 5 LPM concentrator should actually cost and what separates a good one from an overpriced one, here's a clear breakdown.
What Does "5 Litre" Actually Mean?
The "5 litre" or "5 LPM" rating refers to the maximum continuous oxygen flow rate the machine can deliver per minute, not the size of a tank. Most home-care patients are prescribed anywhere from 1 to 4 LPM, so a 5 LPM machine gives enough headroom without straining the compressor, which in turn extends the machine's working life. This is different from portable pulse-dose units, which deliver oxygen in short bursts synced to your breathing rather than a continuous stream.
Typical Price Range in India
A standard 5-litre continuous-flow concentrator from a reputable manufacturer typically costs between ₹30,000 and ₹58,000 in India as of 2026, though prices shift depending on the city, GST changes, and import duty fluctuations on medical devices. Budget imported models can be found for less, but they often compromise on sieve-bed quality (the material that filters nitrogen out of ambient air), which affects long-term oxygen purity.
Factors That Push the Price Up or Down
- Oxygen purity consistency: Machines rated to maintain 90%+ purity even after thousands of hours of use cost more but save money on replacement sooner.
- Sound level: A concentrator running at 40 dB or below is noticeably more livable in a small home, and quieter designs usually cost a bit more.
- Warranty and local service: A 1-2 year warranty backed by an actual service centre in your state is worth paying extra for.
- Compressor type: Oil-free, sealed compressors last longer and are used in higher-priced units.
Where to Compare Machines
Because specifications like purity percentage, noise level, and power consumption vary so much between models, it helps to compare a few side by side before deciding. Retailers such as TCH Medical India publish detailed spec sheets for their 5 LPM range, which is useful when you want to check numbers like decibel rating and power draw rather than relying on a salesperson's word.
5L vs 10L: Which One Should You Buy?
| Requirement | Recommended Size |
|---|---|
| Doctor-prescribed flow of 1-4 LPM | 5 Litre |
| Flow requirement above 4 LPM or ICU-level support | 10 Litre |
| Two family members needing simultaneous use | 10 Litre or two separate 5L units |
Running Costs to Keep in Mind
- Electricity: a 5L concentrator typically draws 300-450 watts, adding roughly ₹300-₹600 a month to your bill if run for 12 hours daily.
- Filters: intake and HEPA filters usually need cleaning weekly and replacement every few months depending on usage and dust levels.
- Servicing: an annual check-up by a qualified technician helps catch compressor wear before it becomes a mid-night emergency.
Before finalising a purchase, always confirm the flow rate your doctor has actually prescribed — buying a larger, more expensive unit than you need is a common and avoidable mistake. For general guidance on oxygen therapy and respiratory care standards, resources from the NHS on home oxygen treatment are a useful independent reference point. With the right size and a reputable seller, a 5-litre concentrator can serve a household reliably for years.
