New stationary oxygen concentrator

A dependable 5 LPM home concentrator that's lighter and easy to live with

The CAIRE Companion 5 is a brand-new, genuine stationary oxygen concentrator for everyday home therapy. It delivers continuous flow from 0.5 to 5 LPM at 90% oxygen purity, in a compact 36-lb cabinet that's easier to move room to room than most home units — and it's rated to work at altitudes up to 9,879 ft.

New unit with CAIRE factory warranty. Home-use concentrator — not intended for air travel. FDA-cleared device.

Why this concentrator

Steady continuous flow

Adjustable from 0.5 to 5 LPM with ±10% (or 200 mL/min) accuracy and 90% oxygen purity — reliable output for daily prescriptions up to 5 liters.

Lighter than most home units

At 36 lb it's a compact stationary concentrator, easier to reposition around the house than heavier cabinets.

Works at higher altitude

Rated for operation up to 9,879 ft (3,011 m), so it holds up in higher-elevation homes where some concentrators struggle.

Quiet enough to live with

Around 50 dB(A) at 2 LPM and 285 W typical draw — a calm, efficient machine for a bedroom or living room.

Genuine and new

A brand-new CAIRE Companion 5 backed by the factory warranty and American Oxygen support — not a refurbished unit.

Frequently asked questions

How much oxygen does the Companion 5 deliver?

Continuous flow from 0.5 to 5 LPM at 90% oxygen purity, with ±10% (or 200 mL/min) flow accuracy.

Is it pulse or continuous flow?

Continuous flow. It provides a steady oxygen stream across its 0.5–5 LPM range — it isn't a pulse-dose unit.

How heavy is it compared to other home concentrators?

36 lb, which is on the lighter side for a stationary 5 LPM unit — easier to move between rooms than many heavier cabinets.

Will it work at high altitude?

Yes. The Companion 5 is rated for operation up to 9,879 ft (3,011 m).

Can I take it on a plane?

No. It's a stationary, home-use concentrator and isn't intended for air travel. For flying, you'd want a portable oxygen concentrator — ask us and we'll help you pick one.

About the sieve columns — do they need service?

Over time, the internal sieve columns are replaced when oxygen purity drops or the unit indicates it, not on a fixed schedule. Our Doral service team can handle it if needed.

Ready for a reliable home concentrator?

The new Companion 5 is a solid, lighter 5 LPM choice for daily home therapy, backed by CAIRE's factory warranty and our Doral, FL team. Call or message us to confirm it matches your prescription and check availability.
