Some fog machines are not designed to work with water, some do work. Adding a small amount of water to the fog machine will produce a thicker and more dense fog that hangs in the air longer than dry fog. Make sure to use distilled water and not mineral or tap water both have impurities that can damage the machine.

It is always advisable to mix the distilled water with a small volume of another fog machine fluid such as glycol or glycerin-based fog fluid. This ensures that the air in the room does not become too saturated with water and results in a reduction of visibility due to droplets forming on surfaces like walls, floors, dance floors, etc.

If you use water only, the fog may not last as long as it would using glycol or glycerin-based fog fluid. This is because water-based fog does not contain the same viscosity as glycol or glycerin.

The water particles will dissipate more quickly as the fog machine operates lighter than those of glycol or glycerin. So if you want the fog to linger in the air longer, consider mixing the water with glycerin or glycol.

How to Make Fog Fluid Using Water

The procedure of making fog fluid with water is not complicated. However, for the best results, you will have to get the proportions right.

To make a fog fluid mix, you will need:

  • A one-liter plastic bottle that’s in good condition
  • A measuring cup
  • Distilled Water
  • Vegetable-based glycerin

The fog fluid you will make should have 15% to 35% of glycerin. As mentioned earlier, the more glycerin you use, the thicker and denser the fog will be.

You can also make fog juice without glycerin.

However, don’t add too much glycerin. Otherwise, you may not get any fog at all.

Pour distilled water into the plastic water until it’s about 75% full. Fill it up with glycerin. This mixture will give sufficiently thick fog. If you want lighter, you can reduce the glycerin proportion to a third a cup.

For best results, you should shake the mixture for about 10 seconds. You will get an evenly cloudy mixture.

Pour a small amount of the fog fluid into your fog machine and switch the machine on. It will produce fog as dense and thick as you want it.

If you need to thin the mixture, add a small amount of water at a time until the desired density is reached.

How do you Make Heavy Fog with Water?

To make heavy fog with water, you will need to reduce the proportion of water and increase glycerin. For instance, if you used 20% glycerin and 80% water, you can now use 30%-35% glycerin.

The fog produced will be thick and last longer.

But remember, the more glycerin you use, the less water-based fog fluid will be left in your plastic bottle for future use. So if you want to make heavy fog with a lot of glycerin content, you should buy an extra bottle of distilled water and store it separately from your other supplies.

Will Water Damage my Fog Machine?

Using distilled water won’t damage your fog machine. However, you should be careful not to use mineral water or tap water since both have impurities that may clog and damage your machine.

Again, if you use mineral water or tap water, you will have to clean out your fog machine more often.

Is Water-glycerin Fog Fluid Safe to Breathe?

Yes, water-glycerin fog fluid is safe to breathe. But you should use a protective mask while working in the room where your machine has been operating for long periods and avoid breathing near the machine or any of its outlets.

Also, if you have asthma, you should consult a doctor before using the fog. This is because some people with asthma may get an allergic reaction to the fog machine’s fluid.

Can you Mix Water with Glycol?

Yes. You can mix water with glycol. In fact, glycol-based fog fluid is the most commonly used fog fluid because it creates the densest fog.

You can mix distilled water with glycol to create a good quality fog that will last long and won’t disappear quickly, as happens when you use just water-based fog fluid.

If your goal is to make less dense but still effective fog, go for a mixture of 15%-20% glycol and 80%-85% distilled water. Note, however, that glycol-based fog fluid may cause some side effects, especially to people with asthma and other breathing problems.

Some of the symptoms that result from too much exposure to glycol-based fog include coughing, sneezing, and the feeling of a tight chest.

Therefore, if you have an underlying breathing problem, you may want to take precautions when using this fog fluid.

Do I Need a Mask When using a Fog Machine?

Suppose you are working in an environment where there’s heavy use of a typical dry ice machine, then yes. In that case, it might be advisable to wear protective goggles (or even better – a full face shield) and have some form of respiratory protection like an N95 filtering respirator.

Otherwise, most people should be able to breathe safely while operating their machines at home or in an environment where the fog is not too deep.

However, suppose you have asthma or other breathing problems. In that case, it may be best to consult a doctor before using any dry ice machine because some people with these conditions are sensitive to certain chemicals in the fog and can get severe allergic reactions when they breathe them into their lungs.


You can use water in a fog machine. However, as discussed, you want to be careful about the type of water you use, so you don’t end up damaging your fog machine.

While you can use just water, you will get better fog if you mix the water with another fluid, preferably vegetable-based glycerin.

So go ahead and make your water-based fog fluid today and have some fun with your fog machine. Did you know there is a difference between haze and fog machines?
