The ultra-quiet, super-compact EverFlo Concentrator is ideal for home oxygen users who don't want to deal with a noisy, bulky machine or multiple oxygen tanks. The Everflo is one of the quietest stationary concentrators on the market - only 40 decibels!

  • Convenience: The Everflo is only 31 pounds and rolls around easily on extremely smooth, durable wheels. Plus, there are multiple storage systems like the velcro holding strap for your bubble humidifier and an internal cabinet to store extra tubing. 

  • Durability: The Everflo panel has a simple on/off switch and rotating Flow Meter Knob for easy control. The Flow Meter is recessed and has a metal cannula connector making it much less prone to accidents and repairs. 

  • Power & Cost Savings: The Everflo was exclusively made to reduce oxygen therapy costs. Its advanced motor provides up to 5 liters/minute of Continuous Flow Oxygen all while using less electricity and less heat than competitor models.

Important Notes & Precautions:

If you use a CPAP device: 

  • It is possible to port your oxygen tubing into your CPAP mask and get the benefit of both therapies while you sleep. Many masks were designed to allow both therapies; however, if your mask does not have a port, you may need to connect your oxygen tubing to your CPAP tubing with an Oxygen Enrichment Adapter instead. The Oxygen Enrichment Adapter allows you to feed oxygen into your CPAP tubing using a special adapter to connect your oxygen tubing, allowing you to receive the benefits of both therapies.

  • You should turn the Everflo ON after the CPAP machine is already running. (Do not start the Everflo and then start the CPAP; the CPAP should always start first).


  • There are other precautions you need to follow when using oxygen. For instance, you should not smoke around an oxygen supply device, and you should also keep your device away from heat. Please refer to the user manual for important instructions.

  • At this time, we cannot ship oxygen products to the following states: Idaho, Maine, Tennessee, Louisiana, Hawaii, and Rhode Island.
