Can You Use a Fan and a Dehumidifier at the same time? [Pros & Cons]

Can I use a fan and a dehumidifier at the same time

The warm season is here again and, like everyone else, you’re looking for a way to keep humidity in check? Well, you’re not alone. Humidity can be such a hard nut to crack if you do not know what to do.

The discomfort and frustrating feeling you get in the heat of a disturbing humidity level is not an experience anyone should have. The most effective way to deal with excess indoor humidity is to deploy a dehumidifier. But what about a fan?

Fans are a very popular appliance found in most homes across the world. They are great at producing air and making us feel more comfortable during hot weather.

But, are fans effective at reducing humidity? Can a fan be used with a dehumidifier at the same time? You’ll get answers as you read on.

Do fans reduce humidity?

A fan is not designed to reduce humidity and it is not exactly great at it. If you truly want to reduce moisture content in your room, a fan is not the best choice.

However, by creating a good amount of breeze, a fan may help to evaporate excess moisture and results in you feeling cooler.

As a fan produces those currents of air, it is able to break down molecules of moisture particles in the air on a small scale and may take a few pints off the total relative humidity in your home.

To get back to the question, a fan will not reduce humidity at the rate that you want it to. This is because a fan blows the same humid and warm air back into the room over and again.

It may make you feel a little better, but if you really want to cut down moisture in your home, you’ll need something more than just a fan.

The amount of reaction a fan’s air circulation can get with water Vapor in the room is what determines how much humidity a fan can reduce.

1. Fans for Ventilation

One way a fan can actually reduce significant amounts of moisture in the room is if it is used as a ventilation fan. Here, it has to be placed by the window or an opening, so that it can introduce external air into the room.

Again, you have to be sure that the external climate is less humid than the internal air. Also, introducing cooler air from an external environment with a lower temperature can certainly have a positive effect as far as humidity is concerned.

You can place a box fan close to an open window to make this happen.

2. Fans as Exhaust

You’re certainly used to Kitchen and bathroom extractors. They are fans installed on openings at a top area of a room to move humid air from inside the room to the exterior.

These fans work constantly to reduce warm, humid indoor air by expelling it. If outdoor air is cooler and less humid, you should open the windows to replace what you’re taking out with cooler air.

You can also find box fans with intentional blade rotational features to vent interior air to the exterior.

Should I buy a fan or dehumidifier? Or both?

If you want to reduce the moisture content in your room air, you should buy a dehumidifier. If you simply want some cooling in your room, a fan would do the job.

However, if you want both cooling and reduced humidity, you should get a fan and a dehumidifier. Another important factor to note is that both appliances are complementary to each other.

A fan is regarded as an important component of a humidity reduction system. It can’t do all the work but it certainly has a role to play.

On the other hand, a dehumidifier is a great tool for reducing humidity in your room. Where you have relative humidity surpassing the recommended 60% limit, you need an appliance to bring it back to prescribed levels and a dehumidifier is just the right tool for the job.

However, a dehumidifier is not going to reduce the temperature of a room. So, if a room is warm and humid, it is best to use a fan and a dehumidifier together.

Besides, there’s no harm in buying a dehumidifier and a fan. There are no disadvantages for using them together, maybe except for energy costs.

Can you use a fan and dehumidifier at the same time?

The simple answer is Yes. You can use a fan and a dehumidifier at the same time. It is perfectly okay to run both appliances at the same time.

Whether it’s a box fan, stand fan, ceiling fan or even a portable fan, it is sure to complement the effort of a dehumidifier.

The fan creates a strong breeze, displaces the air in the room and helps to ensure the dehumidifier can collect more air from the room and drain them of moisture.

Also, you’ll not just have the dry air you desire, but a cool one as well. This will result in just the perfect atmosphere for comfort and health.

Important things to take care of when using a fan and dehumidifier at the same time

A fan is an overwhelming appliance and so is a dehumidifier. So, while using them together should do you a lot of good, you have to take caution. Here are a few things you need to be ready for;

1. You’ll need to adjust the settings

Having to run a fan and a dehumidifier at the same time can be overwhelming. To make them work in perfect sync, you’ll have to adjust the level of both appliances in a way that none overpowers the other. It may take time and practice to get used to these adjustments.

2. Consider electricity usage

For every appliance you buy, there’s a corresponding energy charge that comes with it. Using just a fan would cost you a bit, but using it with a dehumidifier will result in extra energy charges.

If you want to prevent this, you may need to alternate their operation. You can use the fan first and then use the dehumidifier afterwards. Bottom line, try and limit how frequently you use them simultaneously.

3. Noise can be a concern

If you’re concerned about noise, using both appliances at the same time can be unsettling. When blades continuously go round and round, there’s bound to be noise.

If you combine this with the dehumidifier motor and fan noise, then it may become disturbing, especially at night. Be sure to go for modern, low-noise appliances to beat the odds.

4. Increased Maintenance costs

Another factor to take note of is the fact that you’ll be maintaining two rather than just one appliance. That is more cost over time.

You should pay attention to personal maintenance like cleaning and unclogging to avoid major maintenance issues.

Benefits and Drawbacks of using a fan and dehumidifier at the same time

Using a fan and dehumidifier at the same time has its benefits as well as its drawbacks, and we’ll see some of them.


  • Humidity is reduced more quickly because the fan complements the job of the dehumidifier.
  • Beyond moisture reduction, cooling is also achieved.
  • There is less pressure on either appliance because they get support from each other.
  • Increased comfort and convenience.


  • There is increased electricity usage and energy charges.
  • Higher initial investment too.
  • If you do not have sufficient power supply to your home, having multiple appliances can put too much pressure on your home’s electricity.

Final Words:

Living in a comfortable home with the perfect temperature and weather is a necessity you should never ignore. It is a known fact that excess humidity can cause a lot of discomfort in your home and, as you have learned, you can use a dehumidifier and a fan at the same time.
