Key facts

48 CDSCO-licensed entities sell oxygen concentrators in India (manufacturers + importers, audit date 1 June 2026)

14 manufacture in India (Bucket A); the rest import or rebrand foreign-made units

Top 5 indigenous manufacturers by composite score: Medequip (Oxymed) — 90.8, Home Medix — 84.2, Medtechlife — 77.3, Helix — 72.6, Walnut Medical — 72.3

Philips EverFlo has been officially discontinued globally by Philips Respironics

BPL Oxy 5 Neo / Oxy 10 Neo are imported from Jiangsu Yuyue, China — not Indian-manufactured

Ez-Life 5 LPM is an imported Longfian JAY-5BW (China) sold under at least five different Indian-brand wrappers

Oxymed is manufactured in India by Medequip with subassemblies sourced from Shenyang Aerti, China — a kit-assembly transparency disclosure

Methodology: 70% documentation weight, 30% market presence; concentrator-specific evidence only

Audit cutoff: 1 June 2026

You bought an oxygen concentrator. Or you’re about to. The box says BPL, Oxymed, Ez-Life, or Philips. You assumed it was made in India by an Indian company — or, for the imports, that the international brand on the box reflects an active, supported product line. In several cases, neither assumption holds.

This article walks through the public CDSCO licence trail for every major oxygen concentrator brand sold in India in 2026 and shows you exactly where each one is manufactured — and what that means for warranty, spare parts, and how long your machine will be supportable after it leaves the dealer’s shelf.

Four findings before we start.

The BPL Oxy 5 Neo and BPL Oxy 10 Neo — among India’s most recognised concentrator brand names — are imported from Jiangsu Yuyue Medical Equipment & Supply Co. in China, under CDSCO import licence IMP/MD/2021/000700. BPL’s actual Indian manufacturing licence (MFG/MD/2022/000092) covers a different product (BPL OXYFLO 5D), and neither licence has been refreshed since early 2023.

The Ez-Life 5 LPM concentrator sold across Indian marketplaces is a Longfian Scitech JAY-5BW manufactured in China and imported by Swami Ortho Aids under CDSCO import licence IMP/MD/2025/000225. The same Longfian JAY-5BW is also sold under at least four other Indian licences — as LONGFIAN-branded by GVS Enterprises, and unbranded under Niscomed, Sachdeva Medline, and Kannu Impex.

The Philips EverFlo — a stationary 5L concentrator still widely listed on Indian e-commerce platforms in 2026 — has been officially discontinued globally by Philips Respironics. Philips India’s import licence covering EverFlo (IMP/MD/2022/000651) has not been refreshed since November 2022. Units still on Indian dealer shelves are clearance inventory with declining post-purchase support horizons.

The Oxymed 5L and 10L stationary models — sold by Medequip Healthcare Solutions out of Bengaluru, with the largest dealer network in the Indian concentrator market — are manufactured in India under CDSCO MFG/MD/2024/000436 (most recent re-issuance 3 February 2026). However, the same model designations (AR-5-N, MAOXY 05, AE-8-S) also appear on Medequip’s import licences for units manufactured at Shenyang Aerti Tech Co., China. This pattern indicates final-stage assembly in India of subassemblies sourced from China — a legitimate, CDSCO-recognised Indian manufacturing operation, but not a full indigenous build from raw components.

None of this is illegal. All four brands hold valid CDSCO licences and the products meet regulatory standards for sale in India. But knowing where your concentrator actually comes from — and how recently the licence trail has been refreshed — changes how you think about service life, spare parts, supply chain risk, and the company you’re trusting with a piece of equipment that may run eight hours a night for the next five years.

How to read where any concentrator comes from

Every oxygen concentrator sold legally in India falls into one of three categories. We’ve classified each major brand using its CDSCO licence record — the primary-source registry maintained by India’s Central Drugs Standard Control Organisation, the legal regulator for medical devices.

A simple rule: whichever CDSCO licence was most recently issued for an entity defines its current operating status. A 2025 manufacturing licence supersedes a 2020 import licence; a 2025 import licence supersedes a 2023 manufacturing licence. The classification reflects what the company is actually doing now, not what it has historically done.

(A Bucket B “hybrid” category exists in the underlying framework for entities holding both manufacturing and import licences. Under the most-recent-licence rule applied in this article, every such entity resolves to either A or C based on which licence was last issued, so Bucket B has no current occupants.)

A. Made in India — indigenous manufacture

Held by an Indian company whose most recent CDSCO licence is MFG/MD/..., with no active import licence for the same product. The unit is manufactured in India.

Fourteen CDSCO-licensed entities currently meet this standard for stationary oxygen concentrators. Examples include Medequip Healthcare Solutions (Bengaluru — Oxymed brand, with a kit-assembly transparency note explained below), Home Medix (Bengaluru — HM-KV and HM-KX), Medtechlife (Gujarat — OXYTEC line, 20+ years in the medical-equipment market), Helix Private Limited (Bengaluru, since 1994 — Inspiron series), Walnut Medical (Mohali — DST-funded indigenous design programme), Nareena Lifesciences (Greater Noida), Mann Electronics (Kota), and Ess Pee Enterprises (Mohali — Evox brand).

What this means for you: spare parts and service depend on an Indian supply chain you can reach directly. If the manufacturer continues in business, support continues. Warranty claims don’t route through international shipping or an importer’s clearance window.

Transparency footnote within Bucket A — the kit-assembly pattern. A small number of indigenous manufacturers hold CDSCO manufacturing licences whose model designations overlap with their own import licences. The clearest case is Medequip (Oxymed) — AR-5-N, MAOXY 05, and AE-8-S appear on both their manufacturing licence and their import licences from Shenyang Aerti Tech, China. This signals that the Indian manufacturing operation is final-stage assembly of subassemblies imported from a Chinese contract manufacturer, rather than full indigenous build from raw components. The manufacturing operation is real, CDSCO-recognised, and employs Indian workers — but the supply chain has a Chinese dependency that buyers should price into the purchase decision.

C. Imported and rebranded with an Indian-sounding name

Held by an Indian importer whose most recent CDSCO licence is IMP/MD/..., with the unit sold in India under an Indian-style brand name. The brand is Indian; the manufacturing is foreign (typically Chinese). Examples include BPL Oxy 5 Neo / Oxy 10 Neo (BPL Medical Technologies importing Yuyue, China), Ez-Life (Swami Ortho Aids importing Longfian, China), and Yuwell-branded units in India (Impact Distributors importing the same Yuyue family that supplies BPL — a striking overlap between two “heritage Indian” and “established Chinese” brand identities sourced from the same factory).

What this means for you: the brand will be unfamiliar to international service networks. If the importer changes brand strategy, exits the category, or fails to renew the import licence, your spare-parts chain has a single point of failure — the Indian importer who holds the licence.

D. Imported and sold under the international brand

Held by an Indian importer whose most recent CDSCO licence is IMP/MD/..., with the unit sold under the original foreign brand. Examples include Philips EverFlo / SimplyGo / SimplyGo Mini (Philips India importing from Flextronics Mexico and Respironics USA), Nidek Nuvo Lite / Nuvo 8 (Nidek Medical India importing from Nidek USA), CAIRE VisionAire / FreeStyle Comfort / NewLife Intensity (Ujjwal Medical Devices), DeVilbiss iGo2 / 525KS / 1025KS (Sanrai Med India), and the Inogen One G5 / Rove series (Sanrai Med, Asia Actual India, and Somno & Respiratory Healthcare each holding parallel import licences for different Inogen models).

What this means for you: international brand recognition; service depends on the Indian importer maintaining the foreign partnership and renewing their CDSCO import licence on schedule. Watch for licence-renewal recency: Philips’s two import licences for concentrators have not been refreshed since 2022 and 2023 respectively, and Philips EverFlo has been globally discontinued. Inogen’s One G5 is being phased out in favour of the Rove series.

Seven brands, exactly where they come from

We’ve profiled seven brands that together represent the bulk of the Indian concentrator market in 2026. Two rebrand imports (Bucket C), one foreign-brand import (Bucket D), and four indigenous manufacturers (Bucket A — one with the kit-assembly transparency note, three with clean indigenous build).

BPL Oxy 5 Neo / Oxy 10 Neo

Sold as: BPL-branded. Actually made by: Jiangsu Yuyue Medical Equipment & Supply Co., Ltd, China. Yuyue model codes: 7F-5E and 7F-5EW (5 LPM); 7F-10 and 7F-10W (10 LPM). Import licence: CDSCO IMP/MD/2021/000700, issued to BPL Medical Technologies Pvt Ltd (Palakkad, Kerala). Last refreshed 19 April 2023. Bucket: C — rebrand import. BPL separately holds CDSCO MFG/MD/2022/000092 for a different product (BPL OXYFLO 5D), but that licence has not been refreshed since January 2023 and the OXYFLO 5D appears to have minimal active market presence. Under the most-recent-licence rule, BPL’s current operating status is importer.

Verify directly at the CDSCO Medical Devices portal — search licence number IMP/MD/2021/000700. The record names Jiangsu Yuyue as the legal manufacturing site for the Oxy 5 Neo and Oxy 10 Neo series.

What this means for you: Yuyue is a major Chinese OEM. The “BPL” name on the box reflects heritage Indian brand equity wrapped around a Chinese-manufactured product. BPL has not refreshed either of its concentrator-related licences in 38 months, which is consistent with category wind-down. Service support may continue for existing warranty customers, but new-unit availability and spare-parts continuity over the next 3–5 years are at structural risk. Buyers currently considering a BPL Oxy unit should weigh the heritage brand reassurance against the licence-renewal signal.

Ez-Life 5 LPM

Sold as: Ez-Life-branded, typically listed as “Ez-Life Oxygen Concentrator 5L” without further attribution. Actually made by: Longfian Scitech Co., Ltd, China. Model JAY-5BW. Import licence: CDSCO IMP/MD/2025/000225, issued to Swami Ortho Aids on 22 April 2025. Bucket: C — rebrand import. The Indian importer holds no manufacturing licence; the Ez-Life name is a marketing wrapper on a Longfian unit.

Verify directly at the CDSCO Medical Devices portal — search licence number IMP/MD/2025/000225. The Longfian JAY-5BW model appears on five distinct CDSCO import licences held by different Indian entities — GVS Enterprises (IMP/MD/2025/000139, sold as LONGFIAN-branded), Swami Ortho Aids (IMP/MD/2025/000225, as Ez-Life), Sachdeva Medline (IMP/MD/2025/000509, unbranded), Niscomed Medical Devices (IMP/MD/2025/000614, unbranded), and Kannu Impex (IMP/MD/2025/000630, unbranded).

What this means for you: the same Chinese unit is sold across the Indian market under multiple Indian-sounding brand names at different price points. If you’ve bought an Ez-Life and want to verify what you actually own, search the CDSCO record for IMP/MD/2025/000225 — the JAY-5BW designation and Longfian Scitech named as the legal manufacturing site will appear directly. Service depends entirely on Swami Ortho Aids; the importer has no published service network outside its registered address, so warranty and spare-parts response is single-point.

Philips EverFlo (with a note on SimplyGo)

Sold as: Philips-branded. Actually made by: Flextronics Manufacturing Juarez, Mexico (for the EverFlo INTL OPI 230V variant sold in India). Import licence: CDSCO IMP/MD/2022/000651, issued to Philips India Limited. Last refreshed 29 November 2022. Not refreshed in 42 months as of audit. Status: Officially discontinued globally by Philips Respironics. The EverFlo product line has been retired by Philips. Units currently sold on Indian e-commerce platforms and through medical-equipment dealers represent clearance inventory.

Philips SimplyGo and SimplyGo Mini (portable concentrators) are imported under a separate Philips India licence IMP/MD/2023/000489 from Respironics Inc., Murrysville PA, USA. That licence was last refreshed in April 2023 (38 months ago) and has not been renewed since.

Bucket: D — foreign-brand import (aging — Philips India’s concentrator licences are not on an active renewal cycle).

Verify directly at the CDSCO Medical Devices portal — search licence numbers IMP/MD/2022/000651 (EverFlo) and IMP/MD/2023/000489 (SimplyGo).

What this means for you: buying an EverFlo in 2026 means buying into a discontinued product line. Philips’s commitment to long-term service continuity for EverFlo customers in India is undefined in publicly verifiable terms — the import licence aging without renewal suggests Philips India is not maintaining the same level of concentrator commitment it had during the 2020–2022 oxygen-surge period. Buyers paying Philips-tier prices on the assumption of long-term institutional support should be aware that the institutional support is shrinking. The SimplyGo portable line is similarly stale-licenced — viable for current purchase but with a weakening renewal signal.

Oxymed 5L / 10L (Medequip Healthcare Solutions)

Sold as: Oxymed-branded, marketed by Medequip Healthcare Solutions Pvt Ltd, Bengaluru. Substantial dealer footprint across Indian e-commerce and B2B platforms (DLI tier 5). Made by: Medequip Healthcare Solutions in Bengaluru, with subassemblies sourced from Shenyang Aerti Tech Co., China. Manufacturing licence: CDSCO MFG/MD/2024/000436, with the most recent re-issuance dated 3 February 2026 — the freshest CDSCO concentrator licence renewal in the entire dataset. New model variant MAOXY05-01 added in this re-issuance. Parallel import licences: Medequip also holds CDSCO IMP/MD/2024/000162 and IMP/MD/2025/000213 covering the same AR-5-N and MAOXY 05 model designations imported from Shenyang Aerti, plus IMP/MD/2024/000475 and IMP/MD/2025/000690 for the P2 portable line imported from Qingdao Kingon Medical. Bucket: A — indigenous manufacture, with kit-assembly transparency note. Under the most-recent-licence rule, Medequip’s February 2026 MFG re-issuance is more recent than their November 2025 IMP renewal, classifying them as a current manufacturer. The model designations appearing on both MFG and IMP licences are the transparency point: the Indian manufacturing operation is final-stage assembly of Chinese-sourced subassemblies, not full indigenous build.

Verify directly at the CDSCO Medical Devices portal — search licence number MFG/MD/2024/000436 (cross-reference with IMP/MD/2024/000162 and IMP/MD/2025/000213 to see the model-code overlap).

What this means for you: Oxymed has the broadest dealer footprint of any indigenous concentrator brand in India and an active manufacturing licence Medequip refreshes on schedule. Buyers prioritising dealer accessibility and service-network breadth will find Oxymed structurally hard to beat. The kit-assembly disclosure matters mainly for buyers prioritising indigenous-sourced supply chain — for buyers prioritising service density and post-purchase reachability, Medequip’s footprint is the strongest in the market.

Home Medix HM-KV 5 LPM / HM-KX 10 LPM

Sold as: Home Medix-branded, manufactured by Home Medix India Pvt Ltd at No.27, KSSIDC Industrial Estate, Rajajinagar, Bengaluru. Made by: Home Medix India Pvt Ltd at the Bengaluru facility. HM-KV 5 LPM (13 kg, ≤40 dB, 320 VA, 93% ± 3% purity, 0.5–5 L/min flow) and HM-KX 10 LPM (25.6 kg, ≤48 dB, 550 VA, 93% ± 3% purity, 0.5–10 L/min flow). Both with a 3-year / 10,000 operating-hour warranty — the longest published warranty in the Indian indigenous concentrator segment. Manufacturing licence: CDSCO MFG/MD/2025/000522, issued 6 August 2025. Bucket: A — indigenous manufacture. Home Medix holds no CDSCO import licence under either related entity name. The HM-KV and HM-KX are not rebadged Chinese units. No model designations on the manufacturing licence overlap with any foreign manufacturer’s listings on any Indian import licence.

Verify directly at the CDSCO Medical Devices portal — search licence number MFG/MD/2025/000522. Single record, Karnataka SLA, models HM-KV - 5 LPM and HM-KX - 10 LPM. No corresponding IMP/MD/... record exists for the brand. Home Medix publishes a spares catalogue (zeolite sieve cartridges, HEPA filters, intake filters, compressors, control PCBs) with part numbers — the cleanest published parts-pipeline disclosure in the segment, and a structural difference from importers and kit-assemblers whose spares routing is mediated by an importer or contract manufacturer.

What this means for you: spare parts source from a Bengaluru factory reachable by phone. Service routing is direct; warranty claims don’t pass through an importer’s clearance process. The 3-year / 10,000-hour warranty is documented commitment, not marketing claim — it appears in Home Medix’s product brochures and the published service documentation linked from each product page. The dealer footprint (DLI tier 3) is more modest than mass-market top brands, but the supply-chain risk profile is structurally different from any Bucket C or D brand at the same price point — and, on the kit-assembly disclosure axis, from Oxymed at the indigenous-but-Chinese-subassembly end of Bucket A. For buyers prioritising indigenous manufacture with direct manufacturer reachability, published spares access, and the longest warranty in the category, this is one of the cleaner choices in the market.

Medtechlife OXYTEC

Sold as: Medtech / OXYTEC-branded. Manufactured by Medtechlife Pvt Ltd, Gujarat. Models OXYTEC Smart, OXYTEC Life, OXYTEC Classic, OXYTEC Pro. The company claims 20+ years in the Indian medical-equipment market. Made by: Medtechlife at their Indian facility. Manufacturing licence: CDSCO MFG/MD/2023/000525, issued 23 May 2023. Bucket: A — indigenous manufacture. No CDSCO import licence on record for oxygen concentrators.

Verify directly at the CDSCO Medical Devices portal — search licence number MFG/MD/2023/000525. Medtechlife also maintains a direct e-commerce stack with current pricing (typically around ₹22,000–₹26,000 for OXYTEC Smart), formal warranty terms, an explicit service-request workflow, and a published spares catalogue covering HEPA filters, cabinet filters, and small consumables — the most complete published parts pipeline alongside Home Medix in the indigenous concentrator cohort.

What this means for you: Medtechlife operates more as a direct-to-consumer manufacturer than a wide-dealer-network brand. Third-party dealer presence is thinner than Oxymed or Philips (DLI tier 2), but the manufacturer’s own e-commerce infrastructure compensates. Buyers comfortable purchasing through the manufacturer’s own channel get a tightly-integrated warranty-and-service relationship and clean published spares access.

Walnut Medical

Sold as: Walnut-branded. Manufactured by Walnut Medical Pvt Ltd, Mohali, Punjab. Models MS OC-05 SF/DF (5 LPM single and dual flow), MS OC-10 SF/DF (10 LPM single and dual flow). Made by: Walnut Medical at their Mohali facility. Manufacturing licence: CDSCO MFG/MD/2023/000272, issued 25 March 2023. Bucket: A — indigenous manufacture. No CDSCO import licence on record for oxygen concentrators.

Verify directly at the CDSCO Medical Devices portal — search licence number MFG/MD/2023/000272. Walnut’s origin is documented by the Department of Science & Technology (DST), Government of India — they were funded under the DST industrial-policy push for indigenous concentrator manufacturing during the COVID oxygen surge of 2020–2021. Currently visible on the Government e-Marketplace (GeM) with verified stock counts at audit date — the strongest institutional-channel evidence in the indigenous cohort.

What this means for you: Walnut is structurally aligned with institutional and government buyers — GeM channel, DST-supported origin, hospital procurement contracts. Their 1-year warranty is industry-default rather than premium. The published service network is less elaborated than Oxymed or Home Medix. For institutional buyers (hospitals, government health facilities, polyclinics procuring through GeM), Walnut is one of the cleanest documented choices. For retail home buyers prioritising depth of post-purchase support, the indigenous alternatives above (Oxymed for breadth, Home Medix for warranty depth, Medtechlife for spares) may be stronger fits.

Where the indigenous manufacturers actually rank

Of the approximately fifty CDSCO-licensed entities holding concentrator manufacturing or import licences in India, fourteen actively manufacture concentrators domestically without parallel imports. We’ve ranked them on two axes:

Documentation (70% weight) — regulatory licences, technical transparency, service infrastructure, spare-parts pipeline, concentrator-specific maturity
Market presence (30% weight) — dealer footprint, marketplace depth, service-centre geography

All criteria are evaluated on concentrator-specific evidence. Company-wide installations, broad CE / ISO certifications not specifically extending to the concentrator product, and corporate tenure outside the concentrator product category do not count toward the documentation score. A 1941-founded company that began selling concentrators in 2022 counts as four years of concentrator-specific maturity, not eighty-four.

Editorial notes per entry

1. Medequip Healthcare Solutions (Oxymed) — 90.8. Dominant consumer market presence. Transparency footnote: the same model codes (AR-5-N, MAOXY 05, AE-8-S) also appear on Medequip’s CDSCO import licences IMP/MD/2024/000162 and IMP/MD/2025/000213, indicating final-stage assembly in India of subassemblies sourced from Shenyang Aerti Tech Co., China. The Indian manufacturing operation is CDSCO-recognised; the build-stage detail is the disclosure point.

2. Home Medix — 84.2. Concentrator-focused indigenous manufacturer. Longest published warranty in the segment (3-year / 10,000 operating-hour). The brand’s manufacturing licence carries no parallel import licence, distinguishing the HM-KV/HM-KX line from several India-branded concentrators that are imported under separate CDSCO IMP/MD licences. Published spares catalogue and concentrator-specific R&D documentation. For buyers prioritising indigenous manufacture with direct manufacturer reachability, this is one of the cleaner choices in the market.

3. Medtechlife (OXYTEC) — 77.3. Direct-to-consumer manufacturer with the most complete published spares catalogue in the segment — HEPA filters, cabinet filters, and small consumables sold directly via their own commerce stack. Third-party dealer distribution thinner than the top two; the manufacturer-to-buyer relationship is the strongest published in the cohort.

4. Helix (Inspiron) — 72.6. Service-and-biomedical-engineering platform that also manufactures concentrators. Operating since 1994 as a company; concentrator-specific tenure shorter. Strongest filter and calibration support visibility in the cohort. Distribution is Bengaluru-centric — buyers outside Karnataka should confirm local service availability.

5. Walnut Medical — 72.3. DST-funded indigenous design programme (2020–2021 origin during the COVID oxygen surge). Strongest GeM presence with verified stock counts. 1-year warranty (industry default); no published service-network map. Strong for institutional and GeM-channel buyers; thinner post-purchase support for retail consumers.

6. Nareena Lifesciences — 69.3. Diversified medical equipment manufacturer (baby warmers, ECG, infusion pumps, air mattresses, concentrators). DLI tier 3. Concentrator is one product line among many — buyers should weigh diversification against the depth of concentrator-specific service one would get from a specialist.

7. Ess Pee Enterprises (Evox) — 61.5. Substantial Indian dealer presence (DLI tier 3). In-built oxygen purity analyzer is a published differentiator. The brand operates as a division of Ess Pee Enterprises (Mohali, Punjab). Listings from Chinese OEM suppliers reference an “Evox 5S” designation, which warrants additional verification of indigenous-build vs. component-sourcing depth. CDSCO record shows manufacturing licence only — no parallel import licence on record.

8. S. S. Medical Systems — 59.1. Long-established (1941) multi-line medical equipment company with concentrators as one product among ECG, ultrasound, monitors, infection-control, and infusion pumps. Concentrator-specific consumer infrastructure (dealer listings, marketplace presence, dedicated SS-OC service-centre map) is essentially absent from public sources. Institutional and GeM-channel buyers may find them through tendered procurement.

9. Accure Medical — 55.6. Newest CDSCO licence in the audit dataset (issued February 2026). Detailed product page documentation. Limited distribution and service network surface at audit. Worth monitoring as a newer entrant — score may rise as commercial channels develop.

10. Mann Electronics — 54.4. Kota-based manufacturer with own-site product pages and B2B presence. CDSCO, FDA, CE certifications claimed in marketing material. Distribution is Kota-centric — buyers in other regions should expect mail-order or distance support paths.

11. Biome Medtech (OxyBliss) — 54.1. OxyBliss Aura product page is among the more modern in the indigenous cohort, with explicit smart-monitoring and service-tracking language. However, public sources at the time of audit indicate no authorised service centres for the OxyBliss brand in India — a significant post-purchase risk. Buyers should confirm warranty fulfillment pathway directly with the manufacturer before purchase.

12. Vertech Health Solutions (Perfecxa) — 53.9 — under review. Bucket classification is currently under verification. A public marketplace listing identifies the Perfecxa 5-litre product as “Perfecxa Oxygen Concentrator 5 Liter JAY-5BW Oxygen Concentrator” — JAY-5BW is Longfian Scitech’s (China) model designation, also imported into India by GVS Enterprises (IMP/MD/2025/000139), Swami Ortho Aids (IMP/MD/2025/000225), and three other Indian importers under various brand names. Vertech holds an Indian manufacturing licence but no parallel CDSCO import licence on record. The relationship between Vertech’s manufacturing operation and the JAY-5BW model designation requires clarification. We will update this entry when further evidence surfaces.

13. Infitron Medical Technology (Voitron / S.CURE) — 51.6. Better known as a ventilator / respiratory equipment brand. The Oxycure concentrator line has near-zero verifiable retail surface in Indian e-commerce. Company-level claims (21-state presence, 2–5 year warranty) appear in brochure material but are not concentrator-specific in any publicly verifiable form.

14. Hemant Surgical Industries (HSIL) — 51.2. Broad medical-equipment manufacturer operating since 1985. Concentrator-specific product pages, service infrastructure, and spare-parts pipeline are not surfaced in public sources. CDSCO licence is real but the model designation field is blank. Long company tenure does not translate to concentrator-specific evidence.

Why this matters to you

The CDSCO licence trail isn’t just a regulatory technicality. The licence type, model designation, renewal recency, and foreign-manufacturer linkage all map directly to four practical buyer questions.

1. Who fixes it when it breaks?

If you bought a Bucket A unit, your service path is direct: the Indian manufacturer or their authorised dealer is responsible, and you can reach them by phone in business hours. The relevant CDSCO licence (MFG/MD/...) names the legal entity directly.

If you bought a Bucket C or D unit, your service path is mediated by the importer who holds the IMP/MD/... licence. If that importer changes priorities, exits the category, or fails to renew their licence — as appears to be happening with Philips’s EverFlo (last licence refresh November 2022) and SimplyGo (April 2023) lines, with EverFlo now officially discontinued by Philips Respironics globally — your warranty backstop weakens.

2. Are spare parts available in three years?

Concentrators have consumables (HEPA filters, intake filters, humidifier bottles) and wear-out parts (zeolite sieve beds, compressors, control PCBs) that need replacement over a typical 5–8 year service life. Bucket A manufacturers typically maintain parts inventory in India. Importers depend on overseas supply — which means freight lead times, customs clearance, and inventory gaps for non-stocked items.

The Bucket A entries with the most-published spares pipeline are Medtechlife (own commerce stack catalogues filters and small consumables) and Home Medix (published spares catalogue covering zeolite cartridges, filters, and major service parts). Buying from a manufacturer with a published parts catalogue is structurally lower-risk than buying from one that handles parts as ad-hoc service tickets.

3. How long will the product be supported?

Discontinued products lose service coverage. Philips EverFlo has been globally discontinued by Philips Respironics — units still on Indian dealer shelves are clearance inventory with declining post-purchase support horizons. Inogen One G5 is similarly being replaced by the Rove series; G5 stock in India will eventually transition to legacy-support-only.

For currently-active products, the most reliable continuity signal is recent CDSCO licence activity. Recent re-issuances suggest the manufacturer is committed to regulatory compliance — implying ongoing market presence. The freshest Bucket A licence activity in this audit:

Accure Medical: 9 February 2026
Medequip (Oxymed): 3 February 2026 (manufacturing licence re-issue with new model variant added)
Helix: 5 November 2025
Home Medix: 6 August 2025
S. S. Medical Systems: 13 August 2025

4. Where does the supply chain depend on?

A concentrator with all components sourced and assembled in India has supply-chain risk concentrated in India — manageable, with domestic backup options. A concentrator with Chinese-sourced subassemblies (whether kit-assembled in India or imported finished) has supply-chain exposure to Chinese factory continuity, India–China shipping availability, customs and FDI policy shifts, and currency fluctuation. None of these are inherently disqualifying, but they’re factors a buyer should price into the purchase decision.

The cleanest CDSCO-derived signal is the absence of an import licence for the manufacturer of your concentrator. If the same legal entity holds only an MFG/MD/... licence and the model codes don’t appear on any IMP/MD/... record, the unit is — within the limits of CDSCO’s public registry — genuinely manufactured in India from indigenous or domestically-procured components.

Three questions to ask the dealer before purchase

What is the CDSCO licence number on the unit? Should appear on the box or in the product documentation. Cross-reference against the CDSCO public registry — see the next section.
Where is the manufacturer located? If the answer is China and the brand name on the box is Indian, ask which Indian importer holds the IMP/MD/... licence — and what their published service network looks like.
What is the warranty length and what’s the service path? Warranty length below one year, or service path described as “we’ll connect you with someone” rather than a named entity reachable by phone, are red flags.

How to verify any concentrator yourself

Every claim in this article is verifiable. CDSCO publishes its medical-device licence registry publicly at the CDSCO Medical Devices portal. Here’s how to use it to verify any concentrator before purchase.

Step 1: Find the licence number

On the unit’s box, in the user manual, or on the manufacturer’s product page. The format is MFG/MD/YYYY/NNNNNN for manufacturing licences or IMP/MD/YYYY/NNNNNN for import licences. If the seller can’t produce a CDSCO licence number, that’s a red flag — Class B medical devices like concentrators legally require CDSCO licensing for sale in India.

Step 2: Search the CDSCO portal

Go to cdscomdonline.gov.in and use the licence search function. Enter the licence number in the format shown above. The portal returns the registered legal entity, address, issuing authority, device class, intended use, brand name(s), and authorised model designation(s).

Step 3: Read what’s on the licence

The licence record will tell you:

Legal entity that holds the licence — the company legally responsible for the unit
Brand name(s) registered against the licence
Model number(s) authorised — your unit’s model number should appear here
Device class (concentrators are Class B in the CDSCO classification)
Issuing authority — typically the SLA (State Licensing Authority) for the relevant region, or CLA – CDSCO for imports
For import licences: the legal manufacturing site, which names the foreign factory and country

Step 4: Cross-reference

Found only an IMP/MD/ licence, but the brand on the unit is Indian-sounding? You’ve identified a rebrand import (Bucket C).
Found both MFG/MD/ and IMP/MD/ licences from the same Indian entity covering the same model codes? You’ve identified a kit-assembly pattern.
Found only an MFG/MD/ licence with no IMP/MD/ companion for the same model? You’ve identified genuine indigenous manufacture (Bucket A).

Step 5: Check renewal recency

Note the “Issued on” date. CDSCO licences run on five-year cycles, so a licence issued more than four years ago is approaching renewal. A licence not re-issued in 36+ months in a category with active product evolution can signal declining manufacturer engagement with that product line.

Methodology

This article is based on a structured audit of public CDSCO licence records as of 1 June 2026, supplemented by manufacturer brochures and e-commerce product listings.

Scope

Forty-eight entities holding CDSCO oxygen concentrator licences (manufacturing or import) as of the audit cutoff. Brand-name and licensee-name alias mapping was performed where the brand differs from the licensee’s legal name on the CDSCO record (Oxymed → Medequip Healthcare Solutions; Evox → Ess Pee Enterprises; BPL Oxy Neo series → BPL Medical Technologies as importer of Jiangsu Yuyue; and so on).

Scoring rubric

Each licensed entity is scored on two 100-point axes. The composite score weights documentation at 70% and active market presence at 30%.

Documentation axis (70% weight in composite)

Criterion	Weight	What counts
Regulatory (R)	25	Current CDSCO licence with specific model designation
Technical (T)	15	Published technical specifications: purity, flow range, dB, VA, weight, warranty
Availability (A)	20	Published dealer / distribution channels
Service (S)	20	Published warranty terms, service workflow, named service infrastructure
Spare parts (P)	10	Published spares catalogue or parts inventory access
Maturity (M)	10	Concentrator-specific product tenure and R&D evidence

Market presence axis (30% weight in composite)

Combined Dealer-Listings Index (DLI, 45 weight) measuring unique seller / dealer listings across Indian e-commerce platforms and B2B portals, plus tenure (15), institutional presence (15), brand recall (15), and service geography (10).

Critical methodological constraint

All criteria are evaluated on concentrator-specific evidence. Company-wide installations, broad CE / ISO certifications not specifically extending to the concentrator product, and corporate tenure outside the concentrator product category do not count toward the documentation score. A 1941-founded company that began selling concentrators in 2022 counts as four years of concentrator-specific maturity, not eighty-four.

Bucket classification rule

Each licensed entity is classified by the type of its most recently issued CDSCO licence:

A (Indigenous): Most recent licence is MFG/MD; no IMP/MD on record
A with kit-assembly footnote: Most recent licence is MFG/MD, but model codes overlap with a same-entity IMP/MD licence — indicating final-stage assembly of imported subassemblies
C (rebrand import): Most recent licence is IMP/MD, brand is Indian-style wrapper on foreign manufacture
D (foreign-brand import): Most recent licence is IMP/MD, original international brand retained

A Bucket B “hybrid” category exists in the underlying framework for entities holding both licence types; under the most-recent-licence rule it has no current occupants because every such entity resolves to A or C.

Limitations

CDSCO portal data may have administrative delays of weeks to months between licence issuance and public-record appearance. Brand-name-to-licensee mapping requires inference where the licence record’s “Brand Name” field is blank or generic. Dealer-listing counts are approximations from public sources at audit date and may shift quarter-on-quarter. Market presence reflects English-language public sources accessible from India on the audit date. The methodology does not measure clinical performance, field failure rates, or user satisfaction — only the documentation footprint and market presence available to a careful buyer performing public-record research.

Frequently asked questions

Is BPL Oxy 5 Neo made in India?

No. The BPL Oxy 5 Neo and Oxy 10 Neo concentrators sold in India are manufactured by Jiangsu Yuyue Medical Equipment & Supply Co. in China and imported by BPL Medical Technologies Pvt Ltd under CDSCO import licence IMP/MD/2021/000700. The Yuyue model codes are 7F-5E / 7F-5EW (5 LPM) and 7F-10 / 7F-10W (10 LPM). BPL holds a separate manufacturing licence (MFG/MD/2022/000092) for a different product, BPL OXYFLO 5D, but neither licence has been refreshed since early 2023.

Where is the Philips EverFlo manufactured?

The EverFlo INTL OPI 230V variant sold in India is manufactured by Flextronics Manufacturing Juarez in Mexico (not the USA, which is the location of Respironics, Philips’s parent for the line). Philips India imports it under CDSCO licence IMP/MD/2022/000651. As of 2026, the EverFlo has been officially discontinued globally by Philips Respironics. The import licence has not been refreshed since November 2022. Units still on sale in India are clearance inventory.

Is Oxymed an Indian brand?

Oxymed is an Indian brand, marketed by Medequip Healthcare Solutions Pvt Ltd, Bengaluru. Medequip holds a current CDSCO manufacturing licence (MFG/MD/2024/000436, most recently re-issued 3 February 2026). However, the same model designations (AR-5-N, MAOXY 05, AE-8-S) also appear on Medequip’s import licences for units manufactured at Shenyang Aerti Tech Co., China. This means Oxymed concentrators are manufactured in India in a kit-assembly model — final-stage assembly of Chinese-sourced subassemblies — rather than full indigenous build from raw components.

How do I check if my oxygen concentrator is CDSCO-licensed?

Find the licence number on your unit’s box, in the user manual, or on the manufacturer’s product page. The format is MFG/MD/YYYY/NNNNNN (manufacturing licence) or IMP/MD/YYYY/NNNNNN (import licence). Search the number at the CDSCO Medical Devices portal. The portal will return the registered legal entity, model numbers covered, device class, and (for imports) the foreign manufacturer.

If the seller cannot produce a CDSCO licence number for the unit, do not buy it. Class B medical devices like oxygen concentrators legally require CDSCO licensing for sale in India.

What’s the difference between MFG/MD and IMP/MD licences?

MFG/MD/... is a manufacturing licence — issued to an Indian company that builds a medical device in India. IMP/MD/... is an import licence — issued to an Indian company that imports a finished or semi-finished medical device from a foreign manufacturer for sale in India. A company can hold both for different product lines (or, in the kit-assembly pattern, for the same model codes — indicating final-stage Indian assembly of imported subassemblies).

Which oxygen concentrator brands are actually made in India?

Fourteen CDSCO-licensed entities currently manufacture concentrators in India without parallel import licences for the same product. Top by composite score (June 2026): Medequip (Oxymed) with kit-assembly transparency note, Home Medix (HM-KV / HM-KX), Medtechlife (OXYTEC series), Helix (Inspiron), Walnut Medical (MS OC series), Nareena Lifesciences (NLS series), Ess Pee Enterprises (Evox brand), and several smaller manufacturers. See the full ranking earlier in this article.

Has Philips discontinued the EverFlo concentrator?

Yes. Philips Respironics has officially discontinued the EverFlo product line globally. The EverFlo has been Philips’s flagship stationary 5L concentrator since the early 2000s and is widely listed on Indian marketplaces in 2026, but those listings represent clearance inventory rather than active product supply. Philips India’s import licence for EverFlo (IMP/MD/2022/000651) has not been refreshed since November 2022, consistent with the global discontinuation. Buyers considering an EverFlo in 2026 should be aware that post-purchase parts and service support will be on legacy-support terms.

What is a kit-assembly concentrator?

A concentrator manufactured in India where the major subassemblies — typically the compressor, sieve bed assemblies, and control PCBs — are sourced from a foreign contract manufacturer (most commonly Chinese OEMs like Shenyang Aerti Tech or Jiangsu Yuyue) and final-stage assembled, tested, and labelled in India. The Indian operation may employ workers, hold inventory, and run quality assurance, but the core manufacturing is foreign. Identifiable when the same Indian legal entity holds both MFG/MD/ and IMP/MD/ CDSCO licences covering the same model designations. Kit-assembly is legal and CDSCO-recognised — the disclosure matters for buyers prioritising indigenous supply chain.

Compare specific models

Now that you know where your concentrator actually comes from, the next step is comparing specific models against each other on the things that matter: oxygen purity at rated flow, noise at typical bedside distance, power draw under load, warranty length, and the CDSCO licence trail behind every claim.
