With our expert insights and detailed comparisons, finding your ideal home oxygen solution is just a few clicks away.
What is a Stationary Oxygen Concentrator?
Stationary Oxygen Concentrators are medical-grade devices designed to deliver continuous oxygen therapy in the home. Unlike portable models, stationary units are plug-in systems that provide steady, high-volume oxygen output for patients who require around-the-clock support. They draw in room air, filter out nitrogen, and deliver purified oxygen through tubing connected to a nasal cannula or mask--all without the need for refills or tanks.
Stationary concentrators are ideal for users who spend most of their time at home, need higher oxygen flow rates, or prefer a consistent and maintenance-friendly setup.
Oxygen Flow Rate & Delivery
When selecting a stationary oxygen concentrator, one of the most important factors to consider is flow rate--measured in liters per minute (LPM). Most home concentrators provide up to 5 LPM, which meets the needs of most oxygen users, while high flow models can deliver up to 10 LPM for patients with greater oxygen requirements.
All stationary concentrators provide continuous flow oxygen, ensuring a steady, reliable stream that supports nighttime use, sleep therapy, and respiratory conditions that demand constant delivery. Your doctor’s prescription will indicate the specific flow rate you need.
Power Efficiency & Operation
Because stationary concentrators run continuously, energy efficiency and durability are key considerations. Modern models are engineered to operate quietly and use less power than older generations. Most include built-in alarms for low oxygen purity, power failure, or flow blockages--providing peace of mind for patients and caregivers alike.
Weight, Size & Placement
While portable concentrators are built for travel, stationary concentrators are designed for reliability and long-term performance. Most units weigh between 30–50 pounds, and come equipped with rolling casters and handles for easy movement between rooms. When choosing your model, consider where you’ll primarily use it--such as the bedroom or living area--and ensure the space has good ventilation and access to power.

NOTES: Dimensions and weight are approximations. Typical sound levels for portable oxygen concentrators are measured at a setting of 2. Typical sound levels for home oxygen concentrators are measured at the highest liter flow. Typical sound levels for sleep therapy devices are measured at average therapy settings with an overall accuracy of +/- 2dBA. In all cases an adapter or special tubing is required when using CPAP with an oxygen concentrator. FAA Approval indicated for use on all Commercial Flights departing from or arriving in the US. Contact your airline for any specific requirements. Review manufacturer's specifications and documentation for additional information on product specifications and features. |
