Frequently bought together:


Until now, oxygen concentrators have been very similar - heavy, bulky, noisy, or require frequent maintenance. But EverFlo from Respironics is a unique stationary concentrator that delivers the features homecare providers want and patients deserve. EverFlo reduces operating costs with a design that is:

  • Lightweight - only 31 lbs
  • Smaller and sleeker
  • Easy to store and transport
  • Low maintenance
  • Quiet
  • Simpler for patients to use and maintain

The Right Fit

EverFlo is part of the Right Fit, a complete portfolio of oxygen products and programs inspired by patients and built for business.


Until now, most oxygen concentrators have been bulky, heavy, and require ongoing maintenance by patients and homecare providers. But the 5-liter per minute EverFlo stationary concentrator from Respironics has been designed with a unique set of features to lower the costs of providing oxygen therapy while maintaining ease of use for patients.

Lightweight and easy to transport at 31 pounds

Compact, ergonomic design takes up less space, looks less like a medical device

One of the quietest mainstream concentrators

No homecare provider filter change for an entire year (or 8,000 hours)

Uses less power and produces less heat, so it’s more patient-friendly


A recessed flow meter helps reduce the chance of accidental breakage.


EverFlo’s durable metal cannula connection is less likely to break.



Humidifier Bottle Platform is designed to be compatible with all bottle styles and features an easy-to-use velcro closure.

    NoInsurance had unit well packaged and delivered in just a couple days. Unit was clean and tested as if it was new. Have unit in place for backup or main concentrator.

    First I was surprised that I was able to purchased the night time oxygen concentrator for $450.00. I had been renting when I visit my son for $150.00 per visit, my husband and I decided it was worth purchasing my own, When it came it was like new, better than the one at home that I'm renting. I'm so glad that we decided to buy.
