Where Is the Best Place to Buy an Inogen Oxygen Machine?
Fast Facts: Buying an Inogen from Main Clinic Supply
- What happened: In 2025, Inogen eliminated its independent dealer network and granted exclusive reseller rights to Oxygen Concentrator Store, a retailer owned by the same parent corporation as CAIRE Inc., another major POC manufacturer. Main Clinic Supply was among the independent dealers Inogen dropped.
- What we did next: Rather than pursue another manufacturer's reseller agreement, MCS dropped every remaining manufacturer agreement to achieve 100% independence. Our only loyalty is to the patient.
- Why it matters: Two of the largest POC manufacturers are now linked through a single corporate-owned retail channel. That reduces competitive pricing and independent choice for patients. MCS exists as a fully independent alternative.
- Factory repairs: MCS maintains factory repair certifications. Same technicians, same genuine parts, same Rochester, MN service lab. Repair certifications are completely separate from reseller agreements.
- Same-day service: Most Inogen repairs completed the same day we receive your unit, with overnight return shipping available.
- Gold-standard warranty: MCS warranty includes accidental drop protection, which no manufacturer warranty covers.
- Multi-brand expertise: Inogen, CAIRE, GCE, O2 Concepts, and Rhythm Healthcare. 14+ years, 10,000+ verified reviews.
- Prescription required: All portable oxygen concentrators require a prescription from your healthcare provider.
If you are searching for the best place to buy an Inogen oxygen machine, you have probably seen the phrase "authorized dealer" on a dozen websites. Until recently, we were one of them. For 14 years, Main Clinic Supply held an authorized reseller agreement with Inogen.
We want to be completely transparent about what happened and why it is actually better for you.
What Happened with Inogen
In 2025, Inogen restructured its reseller program. Inogen eliminated its network of independent authorized dealers and granted exclusive reseller rights to a single retailer: Oxygen Concentrator Store. Main Clinic Supply was among the independent dealers Inogen dropped. We are not going to pretend otherwise.
For 14 years, we built our Inogen business on honest advice, competitive pricing, and a factory-certified service lab that could turn repairs around the same day. We earned over 10,000 verified five-star reviews doing it that way. When Inogen chose to end that relationship, we had a decision to make about every other manufacturer agreement we held.
We dropped them all. Every one. Not because we were forced to, but because the Inogen situation made something clear that we had felt for years: authorized reseller agreements serve manufacturers, not patients. If those agreements can be restructured overnight to benefit a manufacturer's corporate strategy, they were never really about protecting patients in the first place.
So we went fully independent. No manufacturer owns us. No reseller agreement controls what we recommend, how we price, or what we tell you about competing products. Our only obligation is to the patient.
Two Manufacturers, One Retailer: Why This Matters
Here is the part of the story that deserves your attention.
Oxygen Concentrator Store, the retailer that now holds exclusive Inogen reseller rights, is operated by AMSR, LLC. AMSR, LLC is a subsidiary of Niterra Co., Ltd., a publicly traded Japanese conglomerate. Niterra also owns CAIRE Inc., one of the largest portable oxygen concentrator manufacturers in the world. This is documented in Niterra's own consolidated financial statements.
In plain terms: Inogen's exclusive retail partner is owned by the same corporation that owns a competing POC manufacturer. Two of the biggest names in portable oxygen are now connected through a single corporate-owned retail channel.
What does that mean for you as a patient?
- Fewer independent voices. The independent dealers who used to compete on price and offer unbiased multi-brand recommendations have been removed from Inogen's authorized network. The remaining authorized channel is owned by a manufacturer.
- Less pricing competition. Independent dealers drove competitive pricing. When retail distribution consolidates under a manufacturer-owned entity, the pressure that keeps prices fair for patients is reduced.
- Recommendations that may reflect corporate interests. When a retailer shares a parent corporation with a manufacturer, the device recommendations patients receive may reflect corporate priorities rather than individual medical needs.
Main Clinic Supply exists as the independent alternative. We are family-owned. No manufacturer has any ownership stake in our business. When our oxygen specialists recommend a device, the only thing influencing that recommendation is your prescription, your lifestyle, and your budget.
What Independence Means for You
When you call Main Clinic Supply at 1-800-775-0942, the conversation starts with your needs. Our oxygen specialists will ask about your prescription, your daily routine, your travel plans, and your budget. Then they will recommend the device that fits your life.
Sometimes that is an Inogen Rove 6. Sometimes it is a CAIRE FreeStyle Comfort. Sometimes it is a device you have never heard of from a manufacturer that does not spend $29.1 million per year on television advertising. Independence means we can tell you that.
- No manufacturer quotas. We are not required to push a specific brand to maintain an agreement.
- No pricing restrictions. We set our own prices based on value, not manufacturer-mandated minimums.
- Multi-brand expertise. We carry and service Inogen, CAIRE, GCE, O2 Concepts, and Rhythm Healthcare. Our specialists know every platform.
- Honest comparisons. We will tell you when a newer, less-advertised device outperforms a legacy brand on display technology, battery efficiency, noise reduction, or weight.
Factory-Certified Repairs: Same Expertise, No Middleman
This is the most important thing to understand: factory repair certifications are completely separate from reseller agreements. The end of our reseller relationship with Inogen changed nothing about our ability to service your equipment.
Our Rochester, Minnesota service lab is led by Mark Luther, Chief Technology Officer, who has spent 14+ years as a factory-trained portable oxygen concentrator technician. The same team. The same genuine manufacturer parts. The same diagnostic equipment. The same same-day repair capability with overnight return shipping.
- Factory-certified technicians trained on Inogen Rove 6, Rove 4, and legacy G-series platforms.
- Genuine manufacturer parts used in every repair.
- Same-day repairs on most Inogen units, completed the day we receive them.
- Overnight return shipping available so you can have your concentrator back as soon as the next business day.
- On-site service lab in Rochester, MN. No outsourcing. No third-party repair shops.
Compare that to buying directly from Inogen, where repairs require shipping your unit to their facility and waiting weeks for it to come back. Or buying from most online resellers who have no repair capability at all and will simply direct you to the manufacturer.
Our Gold-Standard Warranty vs. Manufacturer Warranties
One of the first questions patients ask is: "Will my warranty still be valid?" The answer is yes, and in most cases, our warranty is stronger than what you would get buying directly from the manufacturer.
| Warranty Feature | MCS Gold-Standard Warranty | Typical Manufacturer Warranty |
|---|---|---|
| Defect coverage | Yes | Yes |
| Accidental drop protection | Yes, included | No |
| Repair turnaround | Same-day repair, overnight return shipping available | Ship to manufacturer; often weeks |
| Where repairs happen | MCS on-site service lab, Rochester, MN | Manufacturer facility (location varies) |
| Parts used | Genuine manufacturer parts | Genuine manufacturer parts |
| Who handles your claim | Same team that sold you the device | Manufacturer call center |

The single biggest difference: accidental drop protection. Portable oxygen concentrators go everywhere with you. They get bumped in airport security. They slide off car seats. They get knocked over at family gatherings. No manufacturer warranty covers accidental drops. Ours does.
The Real Question: Who Should You Trust with Your Oxygen?
Forget "authorized" versus "independent" for a moment. The real question is simpler: who do you want on your side when something goes wrong at 8 PM on a Saturday and you need your oxygen concentrator working?
Here is what 14 years and 10,000+ verified customer reviews have taught us about what actually matters when choosing where to buy your portable oxygen concentrator:
- Can they fix it fast? Main Clinic Supply repairs most units the same day. Many competitors have no repair capability. Inogen direct can take weeks.
- Do they know all the options? We carry and service five major POC brands. A manufacturer-tied dealer can only show you what their corporate parent allows.
- Will they tell you the truth? Our oxygen specialists have no manufacturer quotas. If a $1,800 device fits your needs better than a $3,500 one, we will say so.
- Are they still there after the sale? We answer phones seven days a week. Monday 7 AM to 9 PM, Tuesday through Friday 7 AM to 8:30 PM, Saturday 8 AM to 5 PM, Sunday 9 AM to 5 PM. You will talk to a real person who knows oxygen equipment.
- Can you verify their reputation? 10,000+ verified reviews on Shopper Approved. A+ BBB rating. 14 years in business. Rochester, Minnesota, home of the Mayo Clinic.
- Who owns them? Main Clinic Supply is family-owned. No manufacturer, no corporate conglomerate, and no parent company has any ownership stake in our business. Can every dealer you are considering say the same?
Authorization is a business arrangement between a manufacturer and a reseller. It tells you who has a contract. It does not tell you who will take the best care of you.
Important Reminders Before You Purchase
Buying a portable oxygen concentrator is a significant medical and financial decision. No matter where you choose to buy, keep these facts in mind:
- A prescription from your healthcare provider is required for all portable oxygen concentrators. This is a federal requirement for medical oxygen equipment.
- Medicare does not purchase portable Inogen systems for patients. Most private insurance companies take the same position. However, some plans will reimburse all or part of the cost after purchase if you submit the required claim forms.
- All Inogen portable oxygen concentrators meet FAA acceptance criteria for in-flight use. Check with your airline for any carrier-specific requirements before you travel.
- Ask any dealer about their repair capabilities. Can they fix your unit in-house, or will they send you to the manufacturer? This matters more than any badge on a website.
- Compare warranty terms carefully. Ask specifically about accidental damage coverage, repair turnaround times, and whether you will have a single point of contact for warranty claims.
- Ask who owns the dealer. A retailer owned by a manufacturer's parent corporation may not give you the same unbiased recommendation as a family-owned independent specialist.
Frequently Asked Questions
Is Main Clinic Supply an authorized Inogen dealer?
No. In 2025, Inogen eliminated its independent dealer network and granted exclusive reseller rights to Oxygen Concentrator Store, a retailer owned by the same parent corporation as CAIRE Inc. Main Clinic Supply was among the independent dealers Inogen dropped. After that, MCS dropped every remaining manufacturer reseller agreement to achieve total independence. Our oxygen specialists now recommend the best device for each patient across every brand, with no manufacturer influence. We remain factory-certified to repair all leading portable oxygen concentrator brands, including Inogen.
Can Main Clinic Supply still repair my Inogen concentrator?
Yes. Factory repair certifications are separate from reseller agreements. Our Rochester, Minnesota service lab is staffed by factory-trained technicians who perform same-day Inogen repairs using genuine manufacturer parts. Overnight return shipping is available, so you could have your concentrator back as soon as the next business day.
Is my warranty valid if I buy an Inogen from Main Clinic Supply?
Yes. Manufacturer warranties attach to the product, not the dealer. Every new Inogen purchased from Main Clinic Supply ships with the full factory warranty. MCS also provides its own gold-standard warranty that includes accidental drop protection, which no manufacturer warranty covers. All warranty repairs are performed in our own factory-certified service lab, which means faster turnaround than shipping your unit to the manufacturer.
Why is Main Clinic Supply no longer an authorized Inogen dealer?
Inogen eliminated its independent dealer network and established an exclusive reseller relationship with Oxygen Concentrator Store, a retailer owned by the same corporation that owns CAIRE Inc. That consolidation linked two of the largest POC manufacturers through a single corporate-owned retail channel. MCS then dropped every remaining manufacturer agreement to achieve complete independence, so that our only loyalty is to the patient's condition and lifestyle, not any manufacturer's business strategy.
Is Oxygen Concentrator Store owned by a manufacturer?
Yes. Oxygen Concentrator Store is operated by AMSR, LLC, a subsidiary of Niterra Co., Ltd. Niterra also owns CAIRE Inc., one of the largest portable oxygen concentrator manufacturers in the world. This means Oxygen Concentrator Store and CAIRE share the same corporate parent. This is documented in Niterra's publicly filed consolidated financial statements. When a retailer shares a parent corporation with a manufacturer and also holds exclusive reseller rights for a competing manufacturer like Inogen, two major manufacturers are effectively linked through one corporate-owned retail channel.
Does Medicare cover Inogen portable oxygen concentrators?
Medicare does not purchase Inogen portable oxygen concentrators for patients. Most private insurance companies take the same position. However, some insurance plans will reimburse all or part of the cost after purchase if you submit the required claim forms.

Our on-site service lab in Rochester, Minnesota can complete most Inogen repairs the same day we receive your unit. With overnight return shipping available, you could have your concentrator back as soon as the next business day. Compare that to shipping directly to Inogen, which can take weeks.
