When is the best time to use my O2hi unit?
The best time to use your O2hi unit is when you feel tired: after work, studying, exercise or over-indulgences.

Isn’t there a risk of excessive oxygen inhalation?
There is no risk of harmful side effects to your health no matter how long you use your O2hi unit. The oxygen emitted from your unit has a concentration of about 30% which is deemed an extremely safe level for recreational use. Usage of up to 60 minutes a day is considered very safe.

Are there any problems regarding allergens?
Since HEPA filter and anti-bacterial filters are overlapped inside the outlet of the tabletop wand oxygen supplier, this product removes both dust and bacteria.

Are there any cautions when using?
Use in well ventilated area, especially in the presence of burning devices (ovens, fireplaces, etc.). In addition, do not use it if you detect bad odor or exhaust gas. (Dirty smell and gas elements may be concentrated). Keep away from flammables, exhaust gas and bad or unknown odors.

What is that sound I hear shortly after my oxygen session is over?
If humidity is high or your unit has been used for extended periods of time, moisture may be generated and trapped in the oxygen supply stand. Your unit will go into an automatic ventilation operation (see page 8) to clear the moisture. Avoid breathing oxygen during this process.
