If you want to buy oxygen concentrator online India has no shortage of sellers, but not all of them are trustworthy — and a wrong purchase for a family member on home oxygen therapy can be dangerous, not just expensive. Before you pay for any concentrator online, there are nine practical checks that separate a safe, warrantied purchase from a risky one. This guide walks through each check so you know exactly what to verify before you click "buy."
Why It's Risky to Buy Oxygen Concentrator Online Without Checking
Oxygen concentrators are medical devices, not general electronics. A concentrator that has been poorly refurbished, run past its rated hours, or shipped without proper testing can deliver oxygen below the purity a patient needs, which is a serious safety issue for COPD, ILD, or post-COVID patients. Online marketplaces mix genuine sellers with resellers offering unverified or grey-market stock, so due diligence before payment matters as much as the price itself.
9 Checks Before You Buy an Oxygen Concentrator Online
1. Confirm the Seller Is an Authorised Dealer
Check whether the website or marketplace listing is an authorised dealer for the brand (Philips, ResMed, Yuwell, Inogen, Oxymed, etc.). Authorised dealers can provide manufacturer warranty registration; unauthorised resellers often cannot.
2. Verify GST Invoice and Business Registration
A legitimate medical equipment seller will issue a proper GST invoice with their GSTIN, business address, and contact details. Avoid sellers who only accept UPI to a personal account with no formal billing.
3. Check the Oxygen Purity Specification
Look for the stated oxygen concentration (usually 90–96% at rated flow) in the listing. If a listing has no purity specification at all, that's a red flag — it usually means the seller doesn't have proper technical documentation.
4. Match Flow Rate (LPM) to Your Prescription
Your doctor's prescription will specify a required flow rate in litres per minute (LPM), commonly 1–5 LPM for home patients and up to 10 LPM for more severe cases. Buying the wrong capacity — too low — can be medically unsafe.
5. Ask About Warranty Terms in Writing
Get the warranty period (ideally 1–3 years), what it covers (compressor, sieve beds, electronics), and whether service visits are included or chargeable, before you pay — not after delivery.
6. Confirm Whether It's New or Refurbished
Refurbished units are cheaper but should be clearly labelled as such, with running-hours disclosed and a shorter but real warranty. A "new" unit sold at an unusually low price compared to market rate is worth questioning.
7. Check Delivery, Installation, and Demo Support
Reliable sellers offer home delivery with a basic functional demo — showing the flow meter, humidifier setup, and nasal cannula fitting — so the first-time user isn't left guessing. Confirm this is included before ordering.
8. Look for After-Sales Service Coverage in Your City
Ask whether the seller has service technicians or authorised service centers in your city or state. A machine that runs 24 hours a day for months will eventually need filter changes or minor servicing — a seller with only a call-center number and no local service presence can leave you stuck.
9. Read Verified Reviews, Not Just Star Ratings
Star ratings can be inflated. Read a handful of detailed reviews mentioning delivery speed, machine noise level, and how the seller handled any complaints — these tell you far more than an aggregate score.
Typical Price Ranges to Sanity-Check Against
| Concentrator type | Flow (LPM) | ₹ Price range (India, 2026) | Best for |
|---|---|---|---|
| Entry 5L concentrator | 1–5 LPM | ₹28,000 – ₹45,000 | Standard home therapy |
| Premium branded 5L (Philips/ResMed) | 1–5 LPM | ₹42,000 – ₹55,000 | Long-term daily use, reliability priority |
| 10L high-flow concentrator | 1–10 LPM | ₹60,000 – ₹95,000 | Severe respiratory cases, hospital-style use at home |
| Portable oxygen concentrator | 1–3 LPM (pulse) | ₹1,20,000 – ₹2,50,000 | Mobile/travelling patients |
If a listing is priced far below these bands with no explanation, treat it as a warning sign rather than a bargain. See our full oxygen concentrator price in India breakdown for a deeper city-wise and brand-wise comparison.
What to Do After You Receive the Concentrator
- Test it immediately with the nasal cannula and check the flow meter matches the prescribed LPM
- Keep the invoice, warranty card, and seller contact details in one folder
- Set a reminder for filter cleaning (weekly) and professional servicing (annually)
- Ask your home-care nurse or pulmonologist to check the setup on the first day of use

Frequently Asked Questions
Is it safe to buy an oxygen concentrator online in India?
Yes, provided you buy from an authorised, GST-registered dealer who discloses purity specifications, warranty terms, and offers local after-sales service. Verifying these nine checks before payment significantly reduces risk.
What documents should I ask for when I buy oxygen concentrator online?
Always ask for a GST invoice, warranty card, and — where applicable — the manufacturer's serial number so you can verify authenticity and register the warranty if needed.
How do I know if an online price is too good to be true?
Compare the quoted price against typical 2026 India market bands for that brand and flow rate. If it's dramatically lower with no clear reason (clearance sale, damaged packaging, refurbished disclosure), question it before paying.
Can I return an oxygen concentrator if it doesn't work properly?
Reputable sellers offer a replacement or repair window (commonly 7–15 days) for manufacturing defects found on first use. Confirm this return/replacement policy in writing before you complete the purchase.
