Most Indian home-oxygen prescriptions can be served by a 5 LPM stationary concentrator, but the devices in this class are not interchangeable. The differences that matter are simple: rated purity at flow, sound level, weight, power draw, oxygen purity monitoring, voltage tolerance, warranty, and service access.
This page compares the common 5 LPM models in the HHZ product database. Prices are indicative sampled market prices, not fixed offers.

What the table says
The lightest units in this set are Home Medix HM-KV, Nidek Nuvo Lite, AirSep VisionAire, Oxymed Mini, and Philips EverFlo. If the device will stay in one bedroom, weight is secondary. If a caregiver will move it between rooms, a 13-14 kg unit is materially easier to handle than a 25 kg unit.
Noise is the second major separator. Nidek Nuvo Lite and Home Medix HM-KV publish around 40 dB class noise levels. Philips EverFlo and Oxymed Mini are in the mid-40s. BPL Oxy 5 Neo and Jumao are materially louder on published specs and are less attractive for bedside night use unless the unit can be placed outside the sleeping area.
Power draw also matters for long-duration users. A patient using oxygen 15-18 hours per day will see a real electricity cost difference between a 285-320 W unit and a 500+ W unit. Power draw also affects UPS and inverter sizing.
Oxygen purity indicator matters
OPI, OCI, or oxygen purity analyzer support is important for long-term users because sieve-bed degradation is often gradual. A concentrator can sound normal while delivered oxygen purity falls below its rated envelope. Devices without OPI can still be clinically usable, but they need periodic external oxygen-analyzer checks.
For long-term oxygen therapy, HHZ prefers an OPI-equipped unit unless the buyer has reliable access to service checks.
Who should shortlist which type
Choose a lower-noise 5 LPM unit if oxygen will be used overnight. Nidek Nuvo Lite, Home Medix HM-KV, Philips EverFlo, Oxymed Mini, and AirSep VisionAire are the natural shortlist from the data above.
Choose a lower-power unit if the patient uses oxygen most of the day or depends on inverter backup. Dr Diaz, Nidek, AirSep, GVS, S.Cure, and Home Medix are the lower-draw group by published specs.
Choose a heavier but cheaper unit only when the machine will remain fixed in one place and noise is not the primary constraint. Weight is not a clinical spec, but it does determine whether caregivers actually reposition the machine safely.
Bottom line
For a 5 LPM concentrator in India, do not rank by price alone. The practical spec stack is: rated purity, OPI, sound level, power draw, service access, warranty, and then price. A unit that saves INR 5,000 but is too loud for night use or lacks local service is not cheaper in practice.
