Features

Antibacterial Tank Function

This humidifier does not specify an antibacterial tank. Without this feature, regular cleaning is crucial to prevent bacteria and mold growth, ensuring hygienic operation.

Essential Oil Diffuser Function

This humidifier lacks an essential oil diffuser function. Users cannot add essential oils directly to the water, which limits its aromatherapy capabilities and requires alternative methods for scent diffusion.

Night Light Function

The inclusion of a night light function provides a soft, ambient light, making it suitable for bedrooms and nurseries. This adds convenience and enhances the ambiance, offering a calming light source during the night.

Automatic Shut-Off Function

The automatic shut-off function enhances safety by turning off the humidifier when the water tank is empty. This prevents damage to the unit and provides peace of mind, especially when used overnight or unattended.

Adjustable Mist Output Function

The humidifier offers two spray modes: continuous and intermittent, allowing some customization of the mist output. This enables users to adjust the humidity level according to their preferences and the size of the room, providing flexibility for different environments.

Remote Control Function

The humidifier does not come with a remote control. Adjusting settings requires direct access to the unit, which may be inconvenient for some users, especially when placed in hard-to-reach locations.

Overall Rating

The Kiusiy Small Humidifier is a basic, low-cost option for personal humidification. Its small size and USB power make it convenient for travel and office use. However, the build quality and long-term durability may be limited. It's best suited for short-term or occasional use in small spaces.

Humidification Method (Ultrasonic, Evaporative, Steam)
4.0
The product information does not specify the humidification method, but given the price and features, it is likely an ultrasonic humidifier, which is generally quiet and energy-efficient.
Tank Capacity and Run Time
3.0
With a 400ml tank, the humidifier offers a limited runtime, likely suitable for overnight use in a small space, but requiring frequent refills for continuous operation.
Room Size Coverage
2.5
This humidifier is best suited for very small spaces, such as a desk or bedside table. It will not effectively humidify an entire room.
Noise Level
4.0
The product is advertised as quiet, making it suitable for use in bedrooms and offices where noise is a concern. User reviews confirm its quiet operation.
Maintenance and Cleaning
2.5
Maintenance may be more involved due to the recommendation against using distilled water, which can lead to mineral buildup. Regular cleaning is necessary to prevent clogging and maintain performance.
Features (Hygrostat, Timer, Auto Shut-Off)
3.0
The inclusion of an auto shut-off feature is a plus for safety and convenience. However, the absence of a hygrostat or timer limits its functionality compared to higher-end models.
Manufacturer Reliability and Warranty
2.0
Kiusiy is an emerging brand, so long-term reliability is uncertain. The lack of specific warranty information is a concern.
Cost Performance
4.0
At its low price point, this humidifier offers good value for basic personal humidification. However, potential durability issues should be considered.
