A: Hello CV, thank you for your question! We recommend using cool tap water when using your humidifier. While distilled water can be used without harm, it's especially helpful in preventing white dust, particularly if you suffer from respiratory issues or live in an area with high mineral content in the water. However, regular tap water is perfectly fine for most uses. We hope this helps! Let us know if you have any more questions. Bionaire Support Team

A: Hi Veronica! We hope you are healthy and staying safe. Cool Mist (Evaporate Wick) humidifiers gently disperse cool, invisible mist into the air. Dry air is pulled into the system, passing through a saturated wick filter. Moisture is fan-evaporated into the air while sediment, minerals and other impurities are trapped in the filter. The result is clean, pure, refreshing mist. These safe and effective humidifiers work well in larger rooms, and the cool refreshing mist is comforting in arid climates.
