How Long Does It Take For A Dehumidifier To Work?

On average, it could take up to 12 hours for a dehumidifier to work on the first attempt. But it really depends on the room size that you're in.

The smaller the room the faster the dehumidifier will work. 

Just remember to be patient and let it do its job and you feel a difference.  

What You Need To Know About Dehumidifying A Room

What does it actually mean to dehumidify a room? 

They remove humidity aka moisture from the air in your room.

Doing this also eliminates bacteria in the air and protects your home from mold and mildew.

Dampness is never something that you want. So Having a device that actively ‘dries’ the air, is definitely something you want for your household.

There are different ways of dehumidifying a room don’t involve an appliance. Natural ways of removing humidity include:

  • Create extra ventilation (keep windows open)
  • Don’t boil water or have long, steamy showers
  • Grow special humidity-wicking plants
  • Switch to dry heat sources

None of these are quite as effective as using a dehumidifier.

This way, you can leave your windows closed, have 1-hour showers, and grow whatever indoor plants you like, and excess moisture will not be an issue!

So now that we’ve have established that the importance of a dehumidifier, let's talk about how to make sure you are running your dehumidifier the most efficiently!

What Is The Best Time To Run A Dehumidifier?

The best time of day to run your dehumidifier is in the morning at 7 am and at night at 10 pm. This is because these are the most humid times during the day. 

The great part about dehumidifiers is that they can run 24/7. They don’t need to be turned on and off.

And they are usually quiet enough to have on at night and will not interrupt sleeping.

Best time to run a dehumidifier

You might not need to have your think about electricity prices especially for the larger dehumidifiers. 

So, if you are wanting to conserve energy and use your dehumidifier only when necessary, then afternoons and nighttime are the best times.

Other Factors For Quickly Dehumidifying A Room

There are many different factors to consider when using a dehumidifier to make sure that you are getting the best results. 

Size Of The Room

The size of the room is one of the biggest factors to how quickly the dehumidifier will work. The larger the room the more time it will take for the dehumidifier to work.

I know what you're probably thinking.

Why don't I buy a dehumidifier that's rated for a larger room? That should make the process go quicker, right?

Well, let me save you some money. It sounds like a great idea but using a dehumidifier meant for a large room would be complete overkill and a waste of energy.

My advice would be to match your dehumidifier to the room you're going to need it in the most. Then move it to other rooms as needed.

Capacity Of The Dehumidifier

Once the dehumidifier has removed the moisture in the air it's held in a water tank. The amount of water the tank holds depends on your dehumidifier.

The higher the capacity of dehumidifier, the more moisture it can store before it needs to be dumped.

Removing the captured moisture from your dehumidifier is an easy, but it is not something that you want to be doing constantly

So, the larger the tank, the less of a hassle it is. Also most dehumidifiers have an auto shut off feature when the water tank has reach capacity. Which is good because the water won't overflow.

It's bad if you leave and come back to humid house because it shut itself off. Ideally you should be emptying your dehumidifier every one to two days.

If you find yourself needing to do it more, then you may need a larger water tank. 

Make a note on what the capacity of your dehumidifier is. Make sure that it is large enough for your needs, especially if you are going to have it running in a room with high moisture.

Dampness Level Of Your Home

You may have found the perfect sized dehumidifier for your room, but it's not working?

It could be faulty.

It does happen.

Or more likely, the dampness level of your house may be more than you expected.

If you live in a high humidity area or have a lot of people in a small space, then your dampness level will  be higher.

And a standard sized dehumidifier likely will not cut it. So, you need to consider more than just square footage of the room.

If the room has a high dampness level, then you will need to get a higher capacity appliance for it to work effectively.

There are factors that can make one room of a house damper than others. Reasons for a room being damper than others could include:

  • Close to hot showers and other sources of wet heat (kitchens)
  • Types of plants
  • Number of people residing in the area
  • Ventilation levels (number of open windows and vents)

These reasons and more can attribute to your home having varying levels of dampness.

So, you will need to consider this when using dehumidifiers. The more damp your house, the higher capacity dehumidifier you will need regardless of the size of the room.

Design Of Your Room

Size is not the only factor you need to consider when looking at the capacity and size of the dehumidifier required.

The design of the room can also affect things. For example, an open, airy room with maximum ventilation will tend to be less damp and will require less power to dehumidify.

A more closed in room with many darker corners, and more areas that can attract dampness. For example, closed-in closets will attract dampness. So they will require more work to dehumidify.

A larger room that is better designed may be easier to dehumidify than a smaller room that is not as effectively designed. And what's easier - changing the design of a room, or adjusting your mode of dehumidification?

Placement Of Your Dehumidifier.

Placement of your dehumidifier can be just as important as the capacity and quality.

You can have the best rated dehumidifier on the market. But, if it is placed in the wrong spot, you might as well simply flap your arms for all the good it is going to do.

The best place is always going to be in the middle of the room. Sometimes that won't be possible. So, if it's not then second best is to make sure that the dehumidifier is placed in an open area.

The fans should be placed towards the main living area. 

While it may be tempting to place your dehumidifier out of the way against the wall, you will not be doing yourself any favors.

You will be making it work harder than necessary and won't get the best results.

If you must place it out of the way, rather than placing it flush against a wall, have it face sideways somewhat.

This will help the efficiency and you will see much better results.

Height Of Your Dehumidifier

Hot, moist air rises, so the design and height of your dehumidifier can make a difference.

The most effective dehumidifiers are going to be taller ones, as it will be able to capture the moisture from higher up in the room.

Putting your dehumidifier on a table is also a great idea if you have one that's a mini. 

So, if you are looking at two different dehumidifiers, and one is taller than the other, I would always advise on the taller one.

The general rule is the higher the better!

Wrapping It All Up

It can take a half a day before you start to feel a change in the humidity in your home.

There are so many other factors you have to put into the equation that could make it the time longer or shorter.

Remember to add the factors in that we talked about to get a better sense of how long it will actually take to work.

Be patient and you'll be living more comfortably in no time!
