Home oxygen concentrators are powerful devices, and patients often worry about noise and energy costs. CAIRE addressed these concerns with built-in autoFLOW™ and ultraSILENT™ technologies. ultraSILENT™ produces the quietest air intake and exhaust cycles using a 2-chamber muffler for intake and a purge muffler that virtually eliminates all sound during exhaustion. autoFLOW™ technology features a variable valve timing switch that adjusts valve cycle timing based on your flow rate, resulting in a 20% reduction in power consumption (250W at 2.0 LPM). This also reduces sound levels, component strain, system pressures, and operating temperatures, meaning your Companion 5 will last longer without needing repairs.

Despite being one of the quietest and most energy-efficient home concentrators, the Companion 5 delivers impressive oxygen output from 0.5 to 5.0 LPM of continuous flow oxygen—enough for the vast majority of oxygen users. The user-friendly interface features LED lights and audible alarms to notify you of changes in oxygen output or concentration. The flow meter clearly shows exactly how much oxygen you're receiving, and a compartment on the side holds a humidifier bottle for added comfort. Operation is simple and hassle-free.

CAIRE Inc. has been a global leader in oxygen supply manufacturing for 50 years, refining and improving oxygen delivery equipment to help respiratory patients live more active lives. The Companion 5 continues this legacy with a lightweight and compact design that makes storage easy. The sturdy roller base allows you to effortlessly transfer the unit from room to room—from the living room to the bedroom and anywhere in between. With little maintenance needed before 2 years, you can focus on your health rather than equipment upkeep.
