How this humidifier scores for different use cases
Compact size, quiet 24dB operation, and top-fill convenience make it ideal for desktop use. The 0.5-gallon tank can last a full workday, and the aromatherapy feature adds a nice office perk.
BPA-free materials, cool mist only, 24dB whisper-quiet operation, and auto shut-off make it well-suited for nurseries. The small tank size is the main drawback for extended overnight use.
The 24dB noise level is excellent for sleep, and auto shut-off adds overnight safety. However, the 0.5-gallon tank limits runtime compared to larger bedroom humidifiers, potentially requiring mid-night refills.
At 1.48 pounds, it is lightweight and compact enough for travel. However, it is not USB-powered and lacks the ultra-portable form factor of dedicated travel humidifiers.
The 0.5-gallon tank and compact design are fundamentally inadequate for large rooms or whole-home coverage. This unit is designed for small personal spaces only.
No WiFi, no app control, no voice assistant compatibility, and no remote control. This product has zero smart home integration capabilities.
Our Verdict
The MEGAWISE SK7620 is a small, quiet humidifier built for personal spaces. Its 24dB noise level is one of the quietest you will find. That makes it great for your desk or nightstand.
The 0.5-gallon tank claims up to 24 hours of runtime. That is impressive for its size. Variable mist control lets you dial in the right output.
Top-fill design and essential oil compatibility add daily convenience. You can add water and scented oils without any hassle. Auto shut-off keeps things safe when the tank runs dry.
This unit falls short on smart features. You get no WiFi, no app, and no voice control. You also miss out on a humidistat, timer, and night light.
At $35.93, you pay a fair price for a basic personal humidifier. It does the simple things well. Skip it if you need large room coverage or smart home control.
What We Like
- Runs at just 24dB, quieter than a whisper, so it will not wake light sleepers
- Top-fill design lets you add water fast without flipping the unit upside down
- Works with essential oils so you can enjoy calming scents while you sleep
- Auto shut-off turns the unit off when water runs low for safe overnight use
- BPA-free, food-grade materials keep the mist clean and safe for babies
What Could Be Better
- The 0.5-gallon tank is small and may need refilling more than once a day
- No built-in humidistat to measure or control the room's humidity level
- No timer function to schedule automatic on and off times
- No night light feature, which many bedroom and nursery humidifiers include
- No warm mist option for cold and flu season comfort

How long does the MEGAWISE humidifier run on a full tank?
The manufacturer states up to 24 hours of continuous mist from the 0.5-gallon (1.9-liter) tank. Actual runtime depends on your mist setting. Higher mist output will drain the tank faster.

How loud is this humidifier?
It operates at 24dB, which is quieter than a whisper. This makes it suitable for bedrooms, nurseries, and offices where noise is a concern.
Does this humidifier turn off by itself when the water runs out?
Yes. The auto shut-off feature turns the unit off when the water level gets too low. This prevents dry running and adds safety for overnight use.
What size room can this humidifier cover?
The listing states a floor area of 25 square meters, which is about 269 square feet. This suits small to medium rooms like bedrooms, nurseries, and home offices.
