Stationary Concentrator

Home oxygen concentrators are medical devices that deliver a concentrated flow of oxygen to an individual. In fact, an oxygen concentrator takes the ambient room air, concentrates it, and then delivers it to a person through a cannula. There are various reasons why an individual might need supplemental oxygen and it is best to check with your medical provider to see if you need to use a home oxygen concentrator.


Home oxygen concentrators are designed to be more stationary and deliver a continuous or flow of oxygen. Additionally, home oxygen concentrators are much safer than using an oxygen tank and is incredibly easy to operate.

Respironics EverFlo Oxygen Concentrator

Respironics EverFlo Oxygen Concentrator are unique Stationary Oxygen Concentrators for patients looking for something more from their home Oxygen Concentrator used for Respiratory Therapy. Unlike most home oxygen concentrators, the EverFlo is lightweight: only 31 pounds. The Respironics Oxygen Concentrator is compact and quiet, emitting less than 45 dBA. The design innovations of Respironics concentrators require less maintenance. The EverFlo Concentrator features a much more compact, ergonomic design that takes up much less space and produces less heat and uses less power without losing performance. EverFlo Oxygen is available with or without an oxygen purity indicator (OPI).


The patient-friendly design of the Respironics EverFlo Concentrator makes life simpler and easier for oxygen patients. The Respironics small, quiet design uses less electricity, saving oxygen therapy patients money.EverFlo features a compact, non-medical design that fits the patient's surroundings. Heavy and bulky oxygen tanks are not necessary so you can avoid coordinating and scheduling oxygen resupply.


The Respironics EverFlo is very low maintenance. The internal maintenance-free dual filtration system means that only filter changes are required by homecare providers every two years! The EverFlo features a recessed flow meter and a metal cannula connector to prevent any accidental breakage. The optional Oxygen Percentage Indicator accurately and precisely measures the concentration of oxygen being dispensed. This indicator can be vitally important to strict oxygen therapy dosage requirements. Respironics has also reengineered the humidifier bottle connection, making the EverFlo much simpler to use for all patients.
