What humidity level should I target?

30-50% relative humidity is ideal for health and comfort. Below 30% causes dry skin, nosebleeds, and static. Above 50% encourages mold and dust mites.

Is distilled water necessary for humidifiers?

Not necessary for evaporative models, but strongly recommended for ultrasonic humidifiers. Tap water minerals in ultrasonic units create white dust that coats nearby surfaces.
