How to Make DIY Mist Fan: Two Methods

Alright, I am pretty sure that you are willing to grab a brand new mist fan for your home. But, maybe the budget doesn’t allow the purchase of a quality misting fan, because they are not cheap like other fans types. 

Surely, a misting fan is the only low-budget solution when the temperature outside exceeds the 100°F mark. If you don’t have the budget to buy one then the best alternative option is making a DIY mist fan.

Today, in this article our expert will teach you how to make a DIY mist fan using normal household tools. Definitely, it will be far less expensive than the cost of a normal misting fan (around $200 for a good one).  Before we start let us discuss a bit more about misting fans.

The theory behind misting fans is, they force water through a pressure air pump into the tube then to the nozzle producing a fine mist which is then blown by the fan out with the normal airflow.

They use the principle of evaporative cooling, which is the same process used by our bodies when sweating, compared to air conditioners which use vapor-compression refrigeration. Lowering temperature is brought about by water vapor into the air, thus making a misting fan the best option.

You can use the misting fan for various purposes, for example, in the flowerbeds, on livestock, in veterinary clinics, etc. Moreover, misting fans are ideal for the festival, home, pool parties, and even for sports. Pretty much anywhere outside that, you might want to cool down.

Now, you got the basic mechanism and use of a misting fan. So how do we make a DIY misting fan of our own? Keep reading.

How To Make DIY Mist Fan

Method 1 – DIY Mist Fan Using Cheap Ultrasonic Mist Maker/Fogger.

Tools Need For This DIY Project:

  • Plastic bottle
  • Tape/Glue
  • Computer fan/ Dc motor fan
  • Ultrasonic mist module
  • Led adapter
  • Power supply

DIY Mist Fan Using Cheap Ultrasonic Mist Maker/Fogger

Step 1. Prepare your Container

Take a plastic bottle or jar. It should be tall enough to prevent the water from spilling out from the top.  

Cut a small hole using a cutter near the top of your bottle so that the dc motor fan can be placed outside on that hole. We suggest you use a pencil a mark in the bottle with it according to the size of the dc motor.

Step 2. Place the Mist Maker Inside the Bottle.

Cut the end wire of the mist maker with pliers since you have to connect it with a power source. After that task done, put the mist maker inside the bottom of the bottle. It will be even better if you fixed the mist maker’s bottom of the bottle with waterproof glue. The connecting wires should the outside.   

You don’t have any mist maker at your home, isn’t it right. Don’t worry at all. It’s cheap. It only cost 5-10$. There are many options available online but we suggest these two mist makers from Amazon, as they have proven to be the best through our research practically.

Key Features: LED lightings, best to use if you want to use your DIY mist fan outdoor.

Key Features- Without the LED version and best to use while sleeping because it has no lights.

Step 3. Fix the Fan to Your Bottle  

Proceed and fix the fan on the hole you have created on the bottle. You can use a tape to make it intact or stick firmly as well as you can use glue for a more permanent solution.

Step 4. Connect to the Power Supply

Connect everything, i.e., cut and strip wires near the end of your ultrasonic device. Then, connect your ultrasonic module and fan to the LED connector. And connect it to a power source.

Step 5. Testing If Mist Is Working

Put some water in the water bottle and switch on the power supply. Check the mist is working perfectly or not.

Step 6. Put the Humidifier on the Fan

Drop the water that you have to pour inside your humidifier. Because it will be hard for you to put it on the spot if it is filled with water. Put the handmade humidifier in the middle of your fan head. You should fix it on them with permanent glue. You can use this kind of mist maker on a box fan, wall-mounted fan, pedestal fan, and floor fan.

Step 7. Turn ON the Misting Fan

Next up, pour some water again and plug in the fan in the power outlet. You will feel the water droplet coming out from the fan. If not, then check what you have done wrong.


  • The reason why we’re using distilled water is that tap water, lake water, etc. contain mineral contents that can precipitate in the tank and also mist produced can deposit white dust layers around your handmade humidifier bottle. It will limit the bacterial growth in the jar or battle.
  • For proper functionality, you should not place your ultrasonic mister module too deep in the water. Always make sure it’s in the right depth.
  • You should also know that the misting fan works well with a 24 voltage adapter. Any less might cause the mist not to work.
  • The water sensor and ultrasonic mist will automatically shut off if not submerged in water. Therefore, your module is not going to be damaged in case al the water evaporates.

Method 2 – DIY Mist Fan using Aquarium Air Pump.

Tools You May Need:

  • Air pump
  • Valve
  • Plastic bottle
  • Nozzles
  • Tube

Video Instruction:

DIY Mist Fan using Aquarium Air Pump

Step 1. Take a Plastic Bottle

Take a plastic bottle. Make sure that the cap of the bottle is strong enough.

Step 2. Make a Hole On the Top

Make a hole on the cap of the bottle. The size of the hole will be measure according to the nozzle. So that the nozzle can fit into it.

Steps 3. Make a Hole on Bottom

Screw a hole at the bottom of your bottle enough to fit the size of your valve. Stick your valve there, making sure it’s intact. Ideally, it should be a one-way valve in that, and it allows water only to go in and not out. Therefore, your air pump won’t get destroyed or damaged easily.

Step 4. Put Water Inside the Bottle

Fill in your bottle, with water but not full to the brim to allow some air space and close your container with a spring nozzle.

Step 5. Connect the Pump

At this point, connect your tube inside your bottle through the nozzle and out to your fan.

Once done with the connection, that is connecting your air pump to the bottle specifically at the valve, and the container will start filling up with pressure, pushing the water to the tube and out to the fan.

Special Note:

>>We suggest these two aquarium air pumps, ideally for this project.

This one has one outlet, a lesser air pump, preferably ideal for a small size pedestal fan.

This one has two outlets meaning it pumps more air than the one with only one outlet. And thus, the more air pumped, the more droplets of water and mist. Ideally, this is useful for massive size pedestal fan or industrial fan.

>>If you choose the wrong air pump, then the misting will wet your body.

>>You should also be very careful when experimenting with this, be sure of what you’re doing or want to do.


So, you have learned how to make a DIY mist fan at your home using normal household method. Both of the methods are superb effective and easy. You can follow any method depending on the resources you have. 

As we told earlier, misting fans are an efficient and cheap way of cooling you off in most extreme temps. The big plus is you can use it while doing outdoor activities that you can’t use an air conditioner for.

They also have multiple uses like cooling workers doing their job outdoors like in a warehouse whom you hired for some special household task, ensure your children a chilled environment while playing outside, protecting your animals from the hot heatwave of summer and not forgetting the chill effect they bring to your house.
