Our Price:


The EverFlo Oxygen Concentrator is lightweight, low maintenance and quiet.

Our refurbished 31 pound Oxygen Concentrator is quieter than many other units and has a small size and an affordable price. These are refurbished units. Get the benefits of an oxygen concentrator that is ultra quiet without having to pay a premium price.  

Delivery: There may be a one to two week lead time prior to shipping of this unit.

The sound level is only 40 decibels, which significantly reduces noise complaints. It has only two filters so you will spend less money and time on repairs and maintenance. It produces less heat and doesn't require as much electricity to operate.  

Make sure to add on some oxygen tubing to use your new concentrator.

Using with Ozone Therapy

To use this for ozone therapy, which requires low flows of oxygen, you'll need to add on a Low Flow Oxygen Meter. This allows you to regulate air flow from a high output oxygen concentrator. Achieve flow rates from 1/16LPM to 3/4 LPM in 1/16 increments. Then you can use your O2 concentrator for multiple applications.
