How to use?Step 1) Breathe through your mouth around the inhaler?s mouth piece to get a good breath of air. (Not too deep- don?t pass out.) Give yourself a good sized exhale with the inhaler about 10 or so times WITHOUT COUGHING UP ANYTHING to really loosen up the mucus first. (If you can.) The ball should vibrate enough you can feel it in your chest. If you can feel the vibration, angle it at 90 degrees and move upward until you can feel it vibrate the hardest for the longest time. That?s your sweet spot.Step 2) Next, give yourself a big strong breath in (through your mouth) and out (through the inhaler) to lead to some good productive coughs at the end to get it all out. Repeat the 2nd step until you get it all out! Material and Structure: Eco-friendly materials: Made of Food Grade PP,can use it safety.
