AZEUS 2024 Humidifier: Can This 2.8L Cool Mist Unit Really Last 30 Hours in 2026?

How this humidifier scores for different use cases
The 28dB noise level and up to 30-hour runtime suit overnight use well. However, it lacks a night light, sleep mode, and humidistat for automatic humidity regulation.
BPA-free construction, cool mist only, auto shut-off, and 28dB quiet operation meet nursery safety basics. Missing night light and humidistat reduce its nursery-specific appeal.
Compact 3x3x5 inch dimensions and quiet 28dB operation make it a decent desktop option. The 2.8L tank provides a full workday of mist without refilling.
At 2.23 lbs and a very compact footprint, it could work for travel. However, it is not USB-powered and requires a standard outlet, limiting portability.
The 377 sq ft coverage and 250 mL/h mist output are moderate, but the 2.8L tank is too small for sustained large room use. No humidistat means manual humidity management.
No WiFi, no app control, no voice assistant integration, and no remote control. This product has zero smart home capabilities.
Our Verdict
The AZEUS 2.8L humidifier handles the basics well. It fills from the top, cleans easily, and runs quietly at 28dB.
You get up to 30 hours of cool mist from one tank fill. The dual 360-degree nozzles spread moisture across 377 sq ft.
Auto shut-off keeps you safe when water runs low. BPA-free materials make it suitable for baby rooms.
This unit lacks smart features entirely. No WiFi, no app, no voice control. You adjust everything with a manual dial knob.
It also skips a humidistat, timer, and night light. These missing features are common in competing models at this price.
At $44.99, you pay mid-range pricing for a basic humidifier. The ease of use and quiet operation deliver solid everyday value.
This humidifier fits you best if you want simple, quiet moisture for a bedroom or small room. Skip it if you need smart controls or large room coverage.
