Do these humidifiers leave white dust?

Reviewer consensus

Ultrasonic units (Levoit Classic 160, both Dreo models, Everlasting Comfort) can leave fine mineral dust if you use hard tap water — reviewers recommend distilled water or descaling regularly. Evaporative units like the Levoit Superior 6000S don't have this issue because the moisture is wicked rather than atomized.
