How this humidifier scores for different use cases
USB-powered and extremely compact, so it fits a desk physically. However, it requires DIY assembly into a functional humidifier before any actual use.
Ultra-compact and USB-powered, which suits portability. But it requires a DIY enclosure and water reservoir, making it impractical for most travelers.
This is a bare circuit board module, not a finished humidifier. It has no tank, no auto shut-off, and no runtime capacity for overnight bedroom use.
Completely unsuitable for nursery use. No safety features, no auto shut-off, no BPA-free certification, and exposed electrical components make this unsafe around children.
A tiny 1-inch atomization module cannot humidify any meaningful space. It has no tank, no coverage area rating, and minimal mist output.
No WiFi, no app control, no smart features of any kind. This is a raw electronic component with no connectivity options.
Our Verdict
This is not a humidifier. It is a pack of 4 raw circuit board modules for DIY projects.
You need electronics skills, a water container, and wiring knowledge to make this work. Beginners should look elsewhere.
The 5V USB power and ultra-fine 5-micrometer spray holes make these modules good building blocks. Each board measures just 1 inch across.
At $9.99 for four pieces, the price is fair for makers and hobbyists. You pay about $2.50 per module.
These modules lack every safety and convenience feature you expect from a finished humidifier. No tank, no auto shut-off, no controls.
Buy this only if you plan to build your own humidifier from scratch. For everyday home use, choose a complete unit instead.
What We Like
- You get 4 atomizer modules for just $9.99, costing about $2.50 each.
- USB 5V power works with any phone charger, power bank, or computer port.
- Ultra-fine 5-micrometer spray apertures create very fine mist particles.
- 740 dense spray holes on each atomization plate boost mist quality.
- Tiny 1-inch size fits inside almost any DIY humidifier project.
What Could Be Better
- No water tank included. You must build your own reservoir.
- No auto shut-off feature to prevent dry running or overheating.
- No variable mist control. The module runs at one fixed output level.
- No timer, no sleep mode, and no humidity display of any kind.
- Requires soldering or wiring skills. This is not a ready-to-use humidifier.

Frequently Asked Questions
Common questions about4Pcs USB Humidifier Module USB Spray Module Circuit Board Atomization Module 5V Atomization Plate Circuit Board Atomization Module Atomizer DIY Incubation Experimental Equipment
Is this a complete humidifier I can use right away?
No. This is a set of 4 bare atomizer circuit boards. You need to build a housing, add a water container, and wire the USB connection yourself.
What power source does this module need?
Each module runs on 5V USB power. You can use a phone charger, power bank, or computer USB port. Red wire is positive, black wire is negative.
How fine is the mist this module produces?
The atomization plate has 740 spray holes with 5-micrometer apertures. This creates ultra-fine mist particles that stay airborne and do not wet surfaces.
Does this module have auto shut-off when water runs out?
No. The module has no auto shut-off feature. You must monitor water levels yourself or add your own safety circuit to prevent dry operation.
Can I use this for aromatherapy or essential oils?
The manufacturer lists perfume atomizer and aromatherapy atomizer as intended uses. The ultrasonic technology can atomize liquid solutions beyond plain water.
