How this humidifier scores for different use cases
USB-powered 5V operation suits desktop use, and the tiny size fits any workspace. However, you must build your own enclosure and water reservoir, which limits practical desk use.
At 0.32 ounces per module with USB power, the components are ultra-lightweight and packable. But without a housing or tank, you cannot use it as a portable humidifier out of the box.
This is a bare DIY atomization module, not a complete humidifier. It has no tank, no housing, and no noise insulation, making it completely unsuitable for bedroom use without significant custom assembly.
A raw circuit board module with exposed wiring poses safety concerns around children. No BPA-free certification, no enclosed housing, and no child-safe design elements exist.
The 40-50 mL/h atomization rate per module is extremely low for any room coverage. Even using all four modules together would only produce 160-200 mL/h, far below large room requirements.
No WiFi, no app control, no voice assistant support. This is a basic analog circuit board with only a physical button for two spray modes.
Our Verdict
This is not a humidifier. It is a set of four raw atomization circuit boards for DIY projects.
You need to supply your own water tank, housing, and wicking system. Plan for a real building project before you buy.
Each module pushes out 40-50 mL/h of mist. That is about one-third of what a basic $15 mini humidifier produces.
The USB 5V power is handy. You can plug into a power bank or any USB port. The 300mA draw is very low.
Two spray modes offer some flexibility. Continuous mode runs 4 hours. Intermittent mode cycles 10 seconds on, 5 seconds off for up to 12 hours.
The 108KHz piezo ceramic creates very fine mist at 4-5 micrometers. That is good atomization quality for the price.
At $6.99 for four modules, the per-unit cost is excellent. You get cotton swabs, brackets, and atomizing films with each one.
Buy this only if you enjoy electronics projects. It works well as a component, not as a finished product.
What We Like
- You get four complete atomization modules for just $6.99, making each unit under $1.75
- USB 5V power works with any phone charger, power bank, or computer port
- Two spray modes give you continuous or intermittent mist with a single button press
- Auto shut-off activates after 4 hours in continuous mode and 12 hours in intermittent mode
- The 108KHz ultrasonic frequency produces fine 4-5 micrometer mist particles through 740 micro-holes
What Could Be Better
- No water tank or housing included, so you must build your own enclosure from scratch
- Each module only produces 40-50 mL/h of mist, far below the 150 mL/h budget humidifier average
- No quiet operation mode or noise level rating provided
- No WiFi, app control, or smart home features of any kind
- No BPA-free certification or safety housing to protect against water and electrical contact

Frequently Asked Questions
Common questions about4Pcs USB Humidifieration Atomization Disc Module USB Interface DC 5V Spray DIY Humidifier Control Drive Circuit Board
Can I use this as a humidifier right out of the box?
No. This is a DIY atomization module. You need to build or provide your own water container, housing, and water delivery system. It includes the circuit board, atomizing film, cotton swab, and bracket only.
How much mist does each module produce?
Each module produces 40-50 mL/h of mist. If you connect all four modules, you could get up to 160-200 mL/h total, which covers a very small area like a desktop.
What power source does this need?
It runs on USB 5V DC power at 300mA. Any standard USB port, phone charger, or power bank can run it. The low power draw means a 10,000mAh power bank could run one module for many hours.
How do the two spray modes work?
Press the button once for continuous spray with a steady LED light. It runs for 4 hours then shuts off. Press again for intermittent mode, which sprays 10 seconds and pauses 5 seconds. This mode runs up to 12 hours.
Do I need any special skills to use these modules?
You need basic electronics knowledge. You must connect the red wire to positive and black wire to negative. The white ceramic side faces up for spraying. You also need to design and build a water reservoir system.
