How this humidifier scores for different use cases
The 28dB noise level is quieter than a whisper, and 30-hour max runtime covers a full night without refills. Auto shut-off adds overnight safety, though it lacks a dedicated sleep mode.
BPA-free construction and cool mist only make it safe for babies. The 28dB whisper-quiet operation and auto shut-off are ideal, but it lacks a nightlight or dedicated nursery features.
Compact rectangular design fits on a desk, and 28dB operation won't disturb coworkers. The 2.8L tank lasts a full workday, but 220V voltage limits portability to standard outlets.
The 377 sq ft coverage is decent for a single room but falls short for whole-home use. The 2.8L tank and 250ml/hr output are moderate, not suited for large open spaces.
At 1.5 lbs it is relatively light, but the 2.8L tank makes it bulky for travel. It requires a 220V outlet and is not USB-powered, limiting portability.
No WiFi, no app control, no voice assistant integration. This is a purely manual humidifier with a dial knob, offering zero smart home compatibility.
Our Verdict
The AZEUS GL6676 handles the basics well at a low price. You get 30 hours of cool mist from a 2.8L tank for just $20.39.
The 28dB noise level barely registers. You can sleep, work, or study without hearing it run.
Top-fill and easy-clean design save you time every day. The dual 360-degree nozzles push 250ml/hr of mist across 377 sq ft.
Auto shut-off and BPA-free materials give you peace of mind. These safety features matter most in bedrooms and nurseries.
This humidifier skips smart features entirely. You won't find WiFi, app control, timers, or a humidistat here.
It also lacks aromatherapy and warm mist options. If you want those extras, you need to spend more.
For a simple, quiet bedroom humidifier under $25, this AZEUS delivers solid value. It does the core job without extra complexity.
