Philips Respironics Everflo Home Oxygen Concentrator Review – Features, Benefits

Philips Respironics Everflo Oxygen Concentrator

The Philips Respironics Everflo Oxygen Concentrator is one of the quietest home oxygen units available. Compared to other units, the Everflo offers a lightweight, compact design and high-tech features making it one of the best home oxygen concentrators at an affordable price.

Note: This article is not about the Philips Respironics Everflo Q, which has been discontinued.

Benefits of Using the Everflo Oxygen Concentrator

The Philips Respironics Everflo uses an oxygen percentage indicator (OPI) to maintain consistent and accurate oxygen levels. Most models operate between 87-96% oxygen purity, but when oxygen purity dips below 82%, your unit will sound an alarm ensuring you stay notified.

Another benefit of the Everflo is the reduced power consumption than its predecessor, the Everflo Q. For users who require constant oxygen therapy, the Philips Respironics Everflo does not draw as much power as some other models. Additionally, the Everflo is quiet, operating at about the same volume as a refrigerator.
