Dehumidifier improve the air quality, and make it a healthier environment for everyone in the home. However, a dehumidifier can be a very expensive investment, and it’s not one that everyone can afford.
Making your own homemade dehumidifier will save you money, and easy to make.Â
As a result, I have put this guide together to show you how to make your own dehumidifier that will actually work in your home.

The steps are simple, and hardly any tools are required to make it. Take a look and get started on the construction of your very own DIY dehumidifier.
What You Will Need
- Drill
- Screwdriver
- Hygrometer
- Two buckets
- Chicken wire / mesh
- Pens
- Wire cutters
- Salt
- A stand
- A fan
Step by Step Instructions for Making Your Own Homemade Dehumidifier
Step 1: Use The First Bucket To Create The Base of Your Dehumidifier
Take one of the buckets and drill a hole in the bottom of it. The hole itself should be at least a quarter of an inch in diameter. If you don’t have a drill, you can use a screwdriver to make the hole instead.
It may take longer using this method, however. Please note that for health and safety reasons, you should also be wearing safety goggles while performing this task.
Step 2: Now Use Mesh/Wire at The Botttom Of The DIY Dehumidifier
Now, take the chicken wire (or mesh) and place a piece at the bottom of the bucket to cover up the hole.
You can easily make it the correct size to fit by placing the mesh at the base of the bucket (underneath) and tracing the perimeter using a marker pen. You can then use the wire cutters to get the mesh down to the correct shape.

Step 3: Rock Salt Will Be Added to Allow Moisture to Drip Through
Now, fill the bucket with rock salt – this is the kind that is used to melt ice – and then place it on the stand.
It is very important that the stand you choose is resistant to being dried out or corroded by the rock salt, and it must be porous enough for moisture to drip through.
Ideally, your stand would be similar to a stack of plastic crates, like the ones that are used for milk. The stand can be any height you desire - it all depends on the space you have available.
Step 4: The Second Bucket Will Catch Excess Moitsure from The First BucketÂ
Of course, you need something that will be able to catch the excess moisture that drips out of the first bucket.
Take the second bucket and place it under the stand so that it can catch the moisture easily. This bucket does not require any alteration, it’s simply there to act as a basin.
Step 5: Be Patient when Getting Things Working - It May Take a Few DaysÂ
It can take a few days for it to start working, so make sure you give it time to get started.
Due to the fact that the salt is industrial strength, it should work to pull the moisture from the air, and then release it – dropping the moisture into the bucket under the stand.

Step 6: Be Sure To Do Regular Checks on Your New Dehumidifier
Now that your dehumidifier is up and running, you need to make sure you check it regularly so that you know it is functioning correctly.
You can test the relative humidity of a room by investing in a hygrometer, which is available at most DIY stores and garden centres. You can also increase the size of the dehumidifier, which will further increase its effectiveness.
To Conclude
Making your own homemade dehumidifier is actually a much easier process than people think. It takes hardly any tools, and there are very few components required to dehumidify a room.
I put this guide together so that those who find themselves on a strict budget, or those who don’t want to invest in a dehumidifier, can make one of their own at an incredibly low cost.
The great thing about this one is that it actually works. Just make sure you follow each step carefully, and repeat the sixth step as often as you can.
