In case you haven't heard the buzz in the 'air', extra oxygen offers umpteen benefits — including increased alertness, infection-fighting ability and mental acuity (read: find your car keys faster).

This portable machine purifies the atmosphere with a negative ion generator, and emits 50% more oxygen than you'd find in clean mountain air (the percentage 'climbs' even higher for you city folks). Timer allows for 10, 20 or 30-minute sessions. Includes both headset and tabletop delivery devices, and aromatherapy option.
