WARM & COOL MIST FUNCTIONS & QUIET AS A WHISPER: The gentle, warm mist provided by humidifiers is known to deter growth of harmful bacteria, dust mites, and mold; and relieves cough, irritated nasal passages, and throat. Cool mist keeps nasal passages, sinuses, and skin hydrated in hot, dry weather. And the ultrasonic air diffusion produces less than 28 dB for a quiet humidification that even babies cannot hear LARGE CAPACITY & HUMIDIFYING FASTER: Large capacity allows for up to 36 hours continuous use of the humidifier. Covers up to 60-70? in large room, bedroom, living room, or office. And with a super high mist output up to 450ml/hr, moisturizing the dry air faster.
