i bought a personal one because it gets pretty dry in my house and i figured a bit of extra water vapor would help my sinuses. i know from experience with family owning some that they don’t actually get hot, and i cant feel any warm spots on the diffuser. if i lift the reservoir lid up i just see vapor and a tiny jet of water. how tf does this thing make vapor?

The water is put on a small piezoelectric loudspeaker. It vibrates at an ultrasonic frequency throwing water into the air. The water cools down as it evaporates, so there no energy deficit.
