<b>Words we want to say to you:</b><br> 1. During that time, if you feel like coughing or sneezing, then turn off the compressor. Else, you will be wasting your medicine.<br> 2. Before you start using a nebulizer, make sure to wash your hand with soap and water. Then, dry up your hand.<br> 3. After nebulization, the temperature is a little high but safe. It is normal. Because air flow creates heat by friction. Feel relieved, please.<br> <br> We hope our 2-years' design can meet your requiry and relieve your trouble. <b>
