Short answer
Choose by matching the prescribed continuous flow and oxygen concentration at that flow, then check monitoring, sound and power reporting, warranty, complete GST-inclusive price, package, and service where the machine will be used. The HM-KV has a current manufacturer-published price of ₹42,000 before GST (₹44,100 including 5% GST), with published specifications of 0.5–5 L/min, 93% ± 3%, 13 kg, and ≤40 dB(A). Its product page lists 320 W; the supplied brochure conflicts on power (320 W in the feature panel and 320 VA in the specification grid), so confirm the offered unit’s rating. Its stated warranty is 3 years or 10,000 operating hours, whichever comes first. Consider it only if its published range fits the prescription and its local service and quoted package are confirmed.
The models are compared against the same buying criteria, but the evidence is uneven: manufacturer documents cover core specifications for several models, while Indian price, stock, package, warranty, and service often depend on the exact seller and variant. Older market prices and scraped figures are not treated as current offers or verified specifications.

How to read the comparison
These are manufacturer-published specifications where a primary document is linked. They are not results from a shared bench test: noise measurement conditions, flow performance, and power reporting can differ between manufacturers. For that reason, a sound or wattage figure should be treated as a starting point for questions, not a universal ranking. Power is reported in watts only where the source reports watts; do not compare a VA figure with a W figure as if they were interchangeable.
An oxygen purity indicator or analyzer can alert the user to a concentration problem, but it does not replace prescribed-flow checks, maintenance, or service. Verify the indicator is included on the specific configuration, and ask the supplier how it signals a low reading and who services the unit.
What to confirm before buying in India
Ask the supplier to put these details on the quotation or invoice:
- Exact model and variant, continuous-flow range, and oxygen concentration specification across the prescribed flow.
- Total payable price, including GST, delivery, installation, and any accessories charged separately.
- Package contents by item and quantity. For the HM-KV, the current manufacturer page confirms a nebulizer kit, fitted filter, and one extra HEPA filter; confirm all remaining contents and quantities with the seller.
- Warranty duration and operating-hour limit, whichever comes first, plus exclusions and the party responsible for service.
- Nearest authorized service contact, expected response time, and how replacement filters and other consumables are obtained.
- Compatibility with local mains supply and any stabilizer or backup power requirements; check the manufacturer’s voltage range rather than relying on a generic claim.
- For hill-station use, altitude limits for the precise model and flow setting.
The prescribed flow and a credible local service plan should decide the purchase. HM-KV is the only model in this table with a current manufacturer-published India price captured in this update; other listed models need a current written seller quote and configuration check before total costs can be compared. This is an evidence-coverage difference, not a value or performance ranking. The HM-KV product page reports 320 W; the supplied brochure contains a 320 W feature-panel value and a separate 320 VA value in its specification grid, so check the specific unit documentation.
This is a specification and buying guide, not a substitute for the prescribing clinician’s oxygen plan. Confirm the required flow and use conditions with the clinician and the equipment supplier.
