Why this concentrator

Light & remarkably efficient

At just 18 lb it’s one of the lightest 5L home concentrators, and one of the most energy-efficient — about 100 watts at setting 2. Quiet enough to sit beside you.

Brand-new, factory-warrantied

A genuine, new Inogen At Home backed by the full Inogen manufacturer warranty — no tanks, no refills, no prior use. Real 5-liter home oxygen, straight from the box.

O₂ purity

87–96% oxygen concentration across all five settings. The At Home pulls oxygen out of the room air and concentrates it to medical-grade purity, holding it steady from setting 1 through 5.

Frequently asked questions

Is this a new or used concentrator?

This is a brand-new, sealed Inogen At Home — a genuine, FDA-cleared 5L stationary concentrator that has never been used, backed by the full Inogen factory warranty (3-year concentrator). If you'd prefer to spend less, ask us about our Certified Pre-Owned At Home, which carries a 1-year American Oxygen warranty.

Do I need a prescription?

Oxygen concentrators are prescription medical devices. Have your prescription ready and follow the flow setting your physician prescribes. If you have questions about setup, our team is glad to help — but the therapy itself is directed by your doctor.

Can I travel or fly with it?

No — the At Home is a stationary home unit that plugs into the wall, not a portable, and it isn’t made for air travel. For oxygen on the go or on a plane, you’ll want a portable oxygen concentrator. We carry several and can help you choose.

Is it continuous flow or pulse dose?

Continuous flow — a steady, uninterrupted stream of oxygen from 1 to 5 LPM. That’s different from a portable’s pulse-dose delivery and is the type of therapy typically prescribed for higher-need and overnight use.

Can it run all day and overnight?

Yes. The At Home is built for continuous 24/7 use, including overnight, and it’s one of the most energy-efficient 5L concentrators — about 100 watts at setting 2.

What warranty comes with it?

The full Inogen factory warranty — 3 years on the concentrator and 1 year on sieve beds and accessories — on this brand-new, sealed unit. Our team is here for setup questions and local support, though your oxygen therapy itself is directed by your doctor.

Choosing between new and Certified Pre-Owned? We'll help.

A new Inogen At Home gives you brand-new 5-liter home oxygen with the full Inogen factory warranty. If you'd like to compare it with our Certified Pre-Owned At Home, call American Oxygen at (786) 755-8063 or message us and we'll help you choose.

Es el mejor concentrador de flujo continuo que pude encontrar para mi padre. Muchísimo más silencioso que otros modelos de Philips y Drive. Súper compacto. Lo recomiendo para aquel que pueda pagarlo.

The Inogen At Home is an amazing stationary oxygen concentrator! I’m so grateful to have found it because it has allowed me to keep my independence. I can’t say enough good things about it- it’s quiet, efficient, and very user friendly. The best part is that it has made such a big difference in my quality of life. I would highly recommend the Inogen At Home to anyone who is looking for a top-quality oxygen concentrator.
