Features Of 4L Cool Mist Humidifier
Whisper-Quiet Humidification
Using ultrasonic atomization technology, the HM311 reduces sound levels to just 28dB, making it a perfect choice for bedrooms, baby rooms, or workspaces. No gurgling, humming, or fan noise to interrupt your sleep or focus.
4L Large Capacity with 32-Hour Runtime
The extra-large 4-liter tank offers up to 32 hours of continuous mist output, drastically reducing the need for refills. It supports full-day or overnight use in medium to large-sized rooms without interruption.
Dual Intake and Oversized Mist Outlet
Powered by dual air inlets and a 4-inch wide mist outlet, this humidifier produces a supersized mist cloud that is 3x more effective in reducing dry air quickly. It's ideal for fast comfort during dry seasons or in heavily air-conditioned spaces.
Finer Mist Distribution
The high-frequency ultrasonic process produces lighter, finer mist particles, allowing for even air distribution without surface dampening. It creates a consistent humidity level throughout your space while protecting walls, furniture, and floors from excess moisture.
Top-Fill, Modular Design
No flipping or spilling—just lift the lid and pour. The top-fill design makes refilling and cleaning stress-free. Its modular components are easy to detach and clean, ensuring hygienic performance over time.
3-in-1 Functionality
This is not just a humidifier. It also serves as a light ambiance enhancer and an aromatherapy companion (essential oils not included). Add essential oils to enjoy a refreshing atmosphere while soothing your mood.
Adjustable Mist Levels and Nozzle
With three mist levels and a 30° tiltable nozzle, you have complete control over how much moisture is released and where it's directed. Easily adapt to your room size, seasonal climate, or personal comfort needs.
Auto Shut-Off for Safety
An intelligent shut-off system turns off the humidifier automatically when water runs low, helping avoid overheating or damage. This makes it safe to use in nurseries or when left unattended overnight.
Sleek and Portable Build
Designed to be functional and beautiful, the humidifier has a clean rectangular prism shape that fits neatly into any décor. Lightweight and compact, it's easy to move between rooms.
