If the tube is not correctly attached, medicine will now flow through it. **Enjoy a soothing mist from your Nebuliser by ensuring that the tube is not kinked and that all parts are properly connected.** Make sure that your Nebuliser is turned on by checking that the ON/OFF switch is turned green and that you can hear a motor noise. If there is still no air coming out of the tube, unplug the tube and see if you can feel any air pushing out. If not, you may need to change the filter, which is located underneath the blue cap. You can view a tutorial on how to do this by scanning the QR code at the back of the box your Nebuliser came in.
