The POWERbreathe K-Series 'You and I' option provides additional members of your family the opportunity of hygienically experiencing the benefits of this intelligent breathing trainer, from the one POWERbreathe K-Series unit.

POWERbreathe K-Series valve heads (with mouthpiece) are available in three colors and are interchangeable, which means that you don't necessarily need to choose the same color of valve head originally supplied with your POWERbreathe K-Series unit; you can choose a different color for each member of your family.
