How does a homemade ultrasonic humidifier work?
The science behind these ultrasonic mist makers is quite simple. They generate ultrasonic vibrations on a ceramic disk to create water droplets. The pulverized water then creates this fantastic cool mist! Therefore, the ultrasonic humidifiers don’t generate any heat in the process.

Efficiency of the ultrasonic mist maker module
As you can see in this short videos, these mist maker modules are a good way to produce cool mist. It is amazing to see the amount of fog and the effectiveness of this homemade ultrasonic humidifier. You should use distilled water in your DIY humidifier, as the ultrasounds pulverize the water and the particles it contains. If the water contains salts, metals or any contaminants, they will be suspended in the fog and you could see a white dust deposit near the mist fogger. For the same reason, make sure to keep the tank clean and to change the water frequently. You don’t want to breathe any bacteria growing in your humidifier!

How to build a homemade ultrasonic humidifier?
Let’s see how to accomplish this DIY humidifier project. I am using an old juice box as a reservoir for the homemade humidifier. I did cut a hole on the side to insert the mist maker module and placed a computer fan over the hole to cover it afterwards and fixed it with hot glue.
The computer fan should use 24V just like the mist maker. To plug everything together, I used a DC connector plugged to the power supply. I cut and stripped the wires of the fogger to plug them on the DC connector. The red wire should be connected to the positive end of the connector while the black wire should be connected to the negative end. You can connect the fan the same way, in parallel with the mist maker module. Please see the wiring diagram below for more information.
