Frequently Asked Questions

What's the ideal humidity level?

30-50% humidity is ideal for health and comfort. Too low causes dry skin; too high promotes mold. A hygrometer helps monitor levels.

Should I use warm or cool mist?

Warm mist feels comforting and reduces bacteria. Cool mist is better for allergies and summer use. Both work; choose based on preference and season.

How often should I clean my humidifier?

Clean every 2-3 days during use. Mineral deposits and mold growth are common. Frequent cleaning ensures optimal performance and health.

Do humidifiers help with dry skin?

Yes, adding moisture to the air improves skin hydration. Combined with lotions, humidifiers significantly help dry skin conditions.

Can I use tap water in my humidifier?

Tap water works but leaves mineral deposits (white dust). Distilled water is recommended. Some humidifiers have demineralization cartridges.
