My unit experiences an annoying whistling noise – is this normal?

"I have a vapexhale & hydrabomb. I’m really happy with the vape, but it makes a really obnoxious whistling noise when I’m drawing. Is this indicative of a defect in the glass, or is this expected?"

ya mine did that at the beginning too, i also questioned it. over time it either lessened or i got used to it.
if you want less whistling, dont inhale as hard.


The whistling is caused by turbulence in the airflow. This helps the user know they are maximizing extraction. The sound may go away over time, but what I do is I cover the intake on the bottom of the EVO with some medical gauze. It is inert and also helps muffle the whistling.
