How this humidifier scores for different use cases
USB-powered and compact, which suits a desk setting. However, it requires DIY assembly into a functional humidifier before it can be used at a workstation.
At 1.6 ounces and USB-powered, the module is extremely lightweight and portable. However, it requires a separate container and assembly, making travel use impractical.
This is a DIY circuit board module, not a ready-to-use humidifier. It requires assembly and lacks a proper water tank, housing, or quiet-operation design for bedroom use.
Completely unsuitable for nursery use. Exposed electronic components pose safety hazards for children, and there is no BPA-free certification or child-safe enclosure.
The tiny 5V USB-powered atomizer module produces minimal mist output, far too little to humidify any room. It has no water tank or reservoir system.
No WiFi, no app control, no voice assistant integration. This is a bare electronics module with no smart connectivity features.
Our Verdict
This is not a humidifier. It is a pack of 6 bare circuit board modules for DIY electronics projects.
You must build your own humidifier around these atomizer plates. You need a water container, wiring, and basic electronics skills.
The 740 micro-aperture design creates fine 5-micrometer mist. That is impressive for a component at this price point.
Two spray modes give you continuous or intermittent misting. The auto shut-off timer adds a basic safety layer.
7-color LED lighting adds a fun touch to custom builds. You can set it to cycle colors or stay on one color.
At $11.96 for six modules, the per-unit cost is about $2 each. That makes this a strong value for makers and hobbyists.
Do not buy this expecting a plug-and-play humidifier. This product serves DIY builders who want to create custom misting devices.

Frequently Asked Questions
Common questions about6Pcs USB Humidifier Module 5V Humidifieration Atomizer Spray Circuit Ultrasonic Humidifier Board Atomization Plate Disc Drive Board DIY Home
Is this a complete humidifier ready to use out of the box?
No. This is a set of 6 bare atomizer circuit board modules. You need to supply your own water container, enclosure, and USB power source to build a working humidifier.
What power source does this module need?
Each module runs on 5V USB power. You can use any standard USB phone charger, power bank, or computer USB port to power it.
How do I install the spray disc correctly?
The side with the white piezoelectric ceramic ring must face up. That is the spray surface. The all-steel suction surface faces down into the liquid.
Can I use essential oils or concentrated solutions with this module?
The manufacturer warns against overly concentrated solutions because they may dissolve the plastic bracket. Light aroma solutions may work, but use caution.
What are the two spray modes?
Continuous mode runs the mist nonstop. Intermittent mode sprays for 10 seconds then pauses for 5 seconds. Both modes include an automatic shut-off timer.
