Do Dehumidifiers Consume A Lot Of Electricity?

A dehumidifier helps in making you free from all the dust particles, bacteria, and also excessive humidity. Dehumidifiers are an optimal solution to the problem of moisture and dirtiness. But in addition to this, it is also believed these dehumidifiers consume a lot of electricity.

In this article, we are talking about whether it is correct or not that these dehumidifiers charge a sustainable amount of electricity or other energy sources. If that’s the case, then what kind of dehumidifiers should be considered?

Let us first focus on why do we require such dehumidifiers? Here we will be talking about some common reasons for the installation of these dehumidifiers.

  1. Allergy gets triggered: if you are living in a humid climate and also suffer from allergies, then you will better perceive it. In the humid climate, it gets worse. Allergy gets triggered in these extreme humidity situations. A good dehumidifier can help you to resolve your problem of triggering an allergy.
  2. Helps in reducing humidity: this helps in lowering thickness from the air as it condenses the moisture from the air. Humidity is a prime reason for multiple health issues. Only by getting a dehumidifier, you can save yourself from numerous health issues.
  3. Prevention from millipedes and other pests: getting a dehumidifier can help you to get prevention or shield from different millipedes and pests. It can help you to stay away from millipedes, which gets arisen due to excessive humidity.
  4. Preventing from rusting: it helps in prevention from rusting. Due to moisture, different steel and iron items get corroded. If you have a dehumidifier, then it can also help in the prevention of rusting for different iron materials.

So above, we mentioned multiple reasons why people tend to install dehumidifiers in their homes as they are reliable and can assist in various ways, as discussed above.

Now let us look into the concept of whether these dehumidifiers consume a considerable amount of electricity. Firstly let us see how much energy do they use or, in other words;

How Much Does It Cost To Run Dehumidifier?

The average cost to run a dehumidifier is between $0.03 and $0.16 per hour.

The conventional model of energy consumption of electrical dehumidifiers is 280 watts per hour. In simpler words, an electrical dehumidifier consumes up to 4 cents if the total use of power is 15 cents/KW.

The figures mentioned above are surely taken as an approximate ratio but still are charging a high rate of electricity.

Also, it more depends on the level of humidity level in your home. More humidity leads to more consumption of the power, and similar goes for the lesser humidity.

It can be said that the consumption of electricity for a dehumidifier varies over the humidity level in your particular space.

How Can I Make My Dehumidifier More Efficient?

Make use of open windows and fans: the best way to use a dehumidifier would be to make use of open windows and fans. Making more fresh air available for the damp places can help in removing the dampness in a specific manner making the dehumidifier function lesser.

The consumption of energy is more in basements. There is no way for fresh air in there, and as a result, it makes the water vapor along with moisture gets collected in the air.

Get calcium chloride: calcium chloride is best to absorb moisture from the air. It is convenient for saving up your energy in more damp places. This can assist you by absorbing more moisture and then result in lesser electricity consumption by the dehumidifier.

Get yourself an energy-efficient dehumidifier: to get the advantage of saving up your energy; then you can surely get an efficient dehumidifier for yourself. Getting an efficient one would help you in saving a large amount of electricity. Since efficient dehumidifier is likely designed in a certain way, which helps in saving a substantial amount of power. Also, make sure you use the right size dehumidifier.

Cut-off the running time: an appropriate option of energy-saving would be cutting off the running time of the electrical dehumidifier. Making them run for the whole day isn’t needed, so be sure to turn it up when you need it. This will also help optimally in saving up the electricity.

Proper maintenance of electrical dehumidifiers: similar to other electrical appliances, dehumidifiers also require maintenance. If you are thinking about the cost, then it will not cost you that high because dehumidifiers do not need much support.

Timely update of air filters: you will be required to change the air filters after a specific time. Usually, these are of a prolonged duration one can stay for a good enough time. However, you would still need to make a timely update.

Simple processing of these dehumidifiers: the process of maintenance is comparatively more straightforward than other tasks. All you will be needed to do is remove the water from the collection bin and changing of some funnels that are required, and your job is done.


In the above article, we have overlooked several things and facts related to the dehumidifiers electricity usage. It can be said that; YES – dehumidifiers use a lot of electricity, but this consumption can be reduced by opting for different pro tips mentioned in the above article.
