This oxygen concentrator takes in the  surrounding air and removes all air impurities. It then increases the Oxygen levels by 150% and supplies it for inhalation via a headset! 

How to use it?
Starting with morning to get those sluggish metabolic rates going, through out the day to stimulate brain activity and even eliminate hangovers and more importantly use at night to help improve sleeping patterns! 

This machine is ideal for regular daily use!  The user can inhale the oxygen via a head-set or leave the machine running to increase the general oxygen levels and purity in either a domestic or office environment.
