About this item

Product details

💧Large Capacity, Lasting Comfort
The 3.7L humidifier features a convenient top-fill design and delivers up to 35 hours of continuous mist with just one fill. It eliminates the need for frequent refills and creates a soothing environment for bedrooms, nurseries, or offices.

💧Fine Mist, Wide Coverage
Powered by ultrasonic technology, the humidifier releases ultra-fine 5μm mist that can rise up to 40" high. The 360° adjustable nozzle distributes moisture evenly, covering larger areas without leaving damp spots, ideal for large spaces.

💧Quiet Glow for Peaceful Nights
The humidifier operates as low as 28dB, running as quietly as a gentle whisper. Its soft tri-color indicator adjusts with humidity levels, providing a calming glow that won’t disturb your rest while creating a comfortable atmosphere.

💧Precise Humidity Control
With manual & auto modes and 3 mist levels, the humidifier uses a high-precision humidistat to maintain your ideal humidity within 5%. In auto mode, you can fine-tune the humidity in 5% increments for personalized comfort.

💧Safe & Worry-Free Use
Built with Hall sensor, the humidifier monitors water level changes and automatically shuts off on low water or tank removal to prevent dry burn. Made with BPA-free materials, it's safe and reliable for the whole family.

💧Easy to Clean, Hygienic Water Use
Wide top opening allows easy refills and cleaning. Includes a cleaning brush for dead-angle-free maintenance, reducing stagnant water and scale buildup for cleaner, healthier humidification.

💧Aromatherapy for a Soothing Atmosphere
This humidifier features a built-in aroma pad tray that lets you add essential oils for a gentle, calming scent. It helps create a relaxing environment for babies and family alike, supporting restful sleep.

Humidifier

Very good, I got this for my baby who was 2 months at the time. She was super congested and couldn't breathe. So I'm glad this was able to help. Lights up at night.
