Introduction: Easy Homemade Ultrasonic Humidifier for Less Than 10$

About: I really like to experiment and build stuff. I also like to share the things I learned from these various projects. I hope you will find this information useful and that it will inspire you to build great thin…

While searching for a humidifier to use at home, I saw many cool mist ultrasonic humidifiers and wondered if I could build myself a cheap one. This is a homemade humidifier using an ultrasonic mist maker / fogger that I found online. It is an easy DIY humidifier project you can make for less than 10$. As you can see, it is very efficient!

Check the videos for a complete step-by-step guide for building this homemade humidifier or to see a quick test with the ultrasonic module. You can also visit my website for more information about this ultrasonic humidifier DIY project.

As you can see, these ultrasonic modules can make the perfect homemade fog machine. You can use these DIY humidifiers for your home. You can also use these mist makers to make a reptile fogger DIY or to add a smoke effect for your party and Halloween decorations. In addition, the same mist maker modules are used in ultrasonic essential oil diffusers. Finally, I think that one of the coolest utilization of the ultrasonic technology is to create a fake flame illusion for water vapor fireplaces.

Step 1: Preparation of the Plastic Bottle

Get a plastic bottle like the one I’m using. Cut a hole that is about the size of the computer fan, near the top of the bottle. You can now insert the ultrasonic module through this hole.

Step 2: Fix the Fan to the Bottle

Place the fan over the hole. I fixed it using tape, but feel free to use glue for a more permanent solution.

Step 3: Connect Everything to the Power Supply.

Cut and strip the wires near the end of the ultrasonic device. Connect the ultrasonic module and the fan to the LED connector. You are now ready to fill the bottle and plug the power supply to enjoy your homemade humidifier!

    You can also add humidity sensor and automate it! But you need to place sensor far away from humidifier for most accurate results (humidifier will create high humidity around itself so sensors there would be ineffective).


    Question 2 years ago on Step 3

    Any thoughts on adding an automatic fill-valve?
