Im trying to understand whether the steam from a nebulizer should be hot or cold. I bought a Dr. Trust nebulizer, and it provides cold steam, but the medicine still evaporates and works as described in the instruction manual. Is this normal or should it be hot steam instead?

For a nebulizer like Dr. Trust, the steam provided should be a fine, cool mist, not hot steam, as cool mist is more comfortable to inhale and helps prevent irritation to the airways, so the cold steam produced by your nebulizer is appropriate and effective for delivering medication.
