F.W. Klever O Pur Medical Oxygen gas for inhalation 8lt - Swiss Oxygen Bottle 8lt

O-pur is pure oxygen without additives. It increases the oxygen content of your blood.

Ideal for use when you feel difficulty breathing, anxiety, lack of energy. It can also enhance endurance and ease recovery from mental and physical strain.

After 10 inhalations, the level of oxygen in your blood rises by up to 30%. Opur is pure oxygen in a compact portable container with an inhalation cup that releases oxygen, one breath at a time.

It is used by celebrities, professional sportsmen and women. Just a few puffs of pure oxygen can give you a natural revitalization that is much better than stimulants like caffeine.

Instructions for use
Detach the inhalation mask from the bottle.
Invert the mask and replace it in the bottle so that the bottom of the mask fits into the bottle's outlet valve.
Holding the bottle with one hand, place the inhalation mask in the mouth, in such a way that the indentation fits the nose. While inhaling, press the tab on the bottom of the mask with the other hand to release oxygen (flow is heard).
