Stationary Oxygen Concentrators

A stationary oxygen concentrator is a home unit that pulls in room air and delivers a steady, continuous flow of concentrated oxygen. It is for people with low blood oxygen (hypoxemia) from conditions like COPD or pulmonary fibrosis, and it is prescribed by a doctor who sets your flow rate. Stationary oxygen is not a treatment for sleep apnea, which is treated with a CPAP or BiPAP machine. Always use your prescribed flow rate and talk to your doctor about the right setup for you. These units are FSA/HSA eligible.

Stationary vs portable

A stationary concentrator stays at home, plugs into the wall, and gives continuous flow at higher liter rates, which suits overnight and all-day use. A portable oxygen concentrator is lighter and battery-powered for leaving the house, and many deliver pulse-dose rather than continuous flow. Some people use both. For the full range, see all oxygen concentrators.

Shop by flow rate

  • 5 liters per minute (5 LPM): the most common home range, covering most prescriptions. Options include the Spirit 5L, the Phoenix 5L, the DeVilbiss 525DS, the Dynarex 5L, the OxyHome, the Rhythm Healthcare 5L, and the Inogen At Home and Inogen Voxi 5.
  • 10 liters per minute (10 LPM): for a higher prescribed flow, the Drive DeVilbiss 10 Liter delivers up to 10 LPM of continuous flow.

Shop by brand

We carry stationary concentrators from Inogen (the quiet, compact At Home and Voxi 5), Drive DeVilbiss (the 525DS and the high-flow 10 Liter), Rhythm Healthcare, OxyGo, Spirit, Dynarex, and our own Phoenix. Each delivers a steady, high concentration of oxygen, and your doctor sets the flow rate that is right for you.

FAQs

Do I need a prescription for a home oxygen concentrator?

Yes. In the US, home oxygen is a prescription medical therapy, so you need a prescription from your doctor, who also sets your flow rate. Our team can help once you have it.

What is the difference between a stationary and a portable oxygen concentrator?

A stationary concentrator stays at home, runs on wall power, and gives continuous flow at higher liter rates for overnight and all-day use. A portable concentrator is lighter and battery-powered for leaving the house, and many use pulse-dose delivery. Your doctor can advise which fits your needs.

Is a stationary oxygen concentrator used for sleep apnea?

No. Oxygen concentrators supply supplemental oxygen for people with low blood oxygen from conditions like COPD or pulmonary fibrosis. Sleep apnea is treated with a CPAP or BiPAP machine, not with oxygen. If you are unsure what you need, talk to your doctor.

What does 5 LPM or 10 LPM mean, and which do I need?

LPM is liters per minute, the rate of oxygen the unit delivers. Most home prescriptions fall within the 5 LPM range, while a 10 LPM unit covers higher prescribed flows. Use the flow rate your doctor prescribed, and do not change it on your own.

How does a stationary oxygen concentrator work?

It draws in room air, filters out nitrogen, and delivers a high concentration of oxygen through your tubing. It runs continuously on wall power, so there is no tank to refill, and you breathe it through a nasal cannula.

Are stationary oxygen concentrators FSA or HSA eligible?

Yes. With a prescription they are generally FSA and HSA eligible, so you can use pre-tax funds. Keep your itemized receipt and prescription for your account.

How loud is a home oxygen concentrator?

Stationary units make a steady, low hum while running, and quieter models are designed for bedroom use. Check each product page for its noise level.
