How to use


Customer Care    09/03/2019

After exhaling slowly through pursed lips, secure the Breather in your hand and inhale deeply and forcefully for approximately two to three seconds. Notice your stomach and rib cage and the muscles in your neck as you breathe in against resistance. Be sure to relax your upper chest and shoulders.

Sometimes upon inhalation, this product vibrates and makes a noise like it is allowing more air to enter than intended as the interior "stopper" slips. Is this a flaw or by design?
