Our premium mask comes in four sizes. To get the best face mask size fit you should download our sizing guide.
- Length measurements are used to determine the size of the LiveO2 mask that will best fit you. for measurement, the individual facial muscles should be relaxed and jaw closed.
- Place the gauge tip to the deepest point of the nasal root depression (sellion) and note the size indication where the bottom of the chin exits the gauge.
If you are between sizes, we recommend you use the smaller size.
