Frequently Asked Questions
Clear information on shipping, delivery times, warranty status, and return management.
how to choose the right resistance level
It is best to start at level one to check that the diaphragm works without tension in the neck or shoulders. The mechanical dial lets you move up a level once your breathing stays steady for ten consecutive minutes of gentle exercise.
what material is the mouthpiece made of
The part in contact with your lips and teeth is made of flexible medical-grade silicone without chemical additives. The inner body uses ABS polymer and a stainless steel spring resistant to constant moisture.
