Hiswelle HQ-JS2301 8L Humidifier Review: Can It Handle Your Whole Home in 2026?
A large-capacity cool mist humidifier with smart humidity control and aromatherapy at a fair price. Best for bedrooms and large rooms, but lacks WiFi and warm mist options.

How this humidifier scores for different use cases
The 35 dB sleep mode, 16-hour timer, auto shut-off, and ambient lighting make this a strong bedroom pick. The 8L tank provides long overnight runtime without refilling.
The 500 sq ft coverage and 8L tank are well-suited for large rooms. The 4 mist levels and 360-degree nozzle help distribute moisture across bigger spaces.
Cool mist only and auto shut-off are good safety features. However, no BPA-free certification is listed, and the large size may be oversized for a nursery.
At 13x17 inches and 5.68 lbs, this humidifier is too large for most desks. It is designed for floor or table placement in larger spaces, not personal desktop use.
No WiFi, no app control, and no voice assistant compatibility. The remote control and humidistat are the only smart-adjacent features available.
At nearly 6 pounds and 17 inches deep, this unit is far too large and heavy for travel. It requires a wall outlet and is not designed for portability.
Our Verdict
The Hiswelle HQ-JS2301 gives you a big 8-liter tank. That means you can run it up to 16 hours before adding water.
You get 500 square feet of coverage. That handles most bedrooms, living rooms, and home offices well.
The built-in humidistat is a standout feature at this price. It auto-adjusts mist output to keep your room between 40% and 90% RH.
Sleep mode drops noise to 35 dB and turns off the screen. The 7-color night light adds a soft glow if you want it.
You also get an essential oil tray for aromatherapy. The 16-hour timer and remote control add daily convenience.
The biggest gap is smart home connectivity. There is no WiFi, no app, and no Alexa or Google support.
It also lacks warm mist and easy-clean design features. Competitors at this price sometimes include those.
For $99.99, you get solid large-room humidification with good controls. It fits best in bedrooms and living rooms where smart features are not a priority.

How long can this humidifier run on a full tank?
The 8-liter tank can run up to 16 hours depending on your mist level setting. Lower mist levels will extend runtime beyond 16 hours.
How big of a room can this humidifier cover?
It covers up to 500 square feet. That works for most bedrooms, living rooms, and medium-to-large offices.
Can I use essential oils with this humidifier?
Yes. It has a dedicated essential oil tray for aromatherapy. You add oils to the tray, not directly into the water tank.
How loud is this humidifier during sleep mode?
Sleep mode operates at 35 dB, about the level of a quiet whisper. The screen also turns off so light does not disturb you.
Does this humidifier turn off automatically when the water runs out?
Yes. The auto shut-off feature turns the unit off when the water tank is empty. This protects the motor and prevents dry running.
