We recommend an Air Separator that produces at least 70% oxygen.
Fortunately, this includes most refurbished, remanufactured units. If you notice your system does not bring your O2 saturation to at least 98% within 5 minutes, your Air Separator is probably not producing enough oxygen.
We have tested our system down to 50% purity and find that it still produces beneficial results.
Many Air Separators have built in low-oxygen sensors that trigger an alarm when the oxygen threshold falls below 80%. This indicator is very useful. Given the choice to purchase an Air Separator with this feature, or one without — choose the indicator.
