The EverFlo Q with OPI is an affordable, quiet and durable oxygen concentrator. The Q stands for Quiet, and this oxygen concentrator runs at an ultra-quiet 40 decibels. OPI stands for Oxygen Percentage Indicator. The OPI feature is a light on the machine that illuminates and an alarm that sounds when the OPI level deviates from the physicians's initial setting.

The EverFlo Q has all the same features as the original EverFlo, but the Q model is even quieter than the original!
