Can You Use The Caire Companion 5 Oxygen Concentrator All The Time?

Yes. It is safe to use the Caire Companion 5 continuously for longer than 24 hours. This is due to the fact that it uses AC power and does not need to be refilled. By filtering other gases like nitrogen, carbon dioxide, and others, it draws air from the room and purifies it, removing up to 90% of the oxygen. Additionally, it only generates 50 decibels, which is not particularly loud or disturbing even at night.
