How Many Amps Does a Dehumidifier Use

When you use a dehumidifier in your home, you might wonder about the electricity it uses, especially the amps.

Amps measure how much electric current flows through the dehumidifier. This number helps you understand if the dehumidifier uses a lot of electricity and if it’s okay for your home’s electric system.

In this article, we will look at:

  • Does a dehumidifier use a lot of electricity?
  • How many amps does a dehumidifier use?
  • How to find the amps a dehumidifier uses

What is Amps?

Amps is short for amperes and it’s a way to measure how much electricity goes through something. Amps is like seeing how much water goes through that pipe but for electricity instead. When you plug in something like a dehumidifier, it uses electricity and the amount it uses is measured in amps.

Every electrical device needs a certain amount of electricity to work right. This amount is its amps. Knowing the amps helps you make sure you don’t use too much electricity at once, which keeps your home safe and your bills lower.

Does a dehumidifier use a lot of electricity?

A dehumidifier does use electricity to pull water from the air. How much it uses can depend on the size of the dehumidifier and how long it runs. Some people worry that it might make the electricity bill go up a lot. It’s true that a dehumidifier needs power to work, but how much it affects your bill depends on how often you use it and how powerful it is.

For example, if you have a small dehumidifier and you use it just a few hours a day, it won’t use a lot of electricity. But if you have a big one and run it all day and night, it will use more power.

How many amps does a dehumidifier use?

The amps a dehumidifier uses can change based on its size and how strong it is. On average, a dehumidifier uses between 3 to 7 amps when it’s running. This amount can be more for bigger models designed to dry out larger spaces. The power it needs connects to how much water it can pull from the air in a day.

For a regular home dehumidifier, the kind you might use in a damp room or basement, it often uses about 5 amps. But, if you’re using a very big one for a big space, it could use up to 7 amps or more. This is because it has to work harder to clean more air.

Let’s compare this to other things in your house. A light bulb might use about 0.5 to 1 amp, while a big appliance like a fridge can use around 6 to 8 amps. So, a dehumidifier’s power use is somewhere in the middle. It’s not as low as a light bulb but not as high as the biggest appliances

How to find the amps a dehumidifier uses?

To find out how many amps your dehumidifier uses, you can look at its label or manual. It often says there. But if you want to figure it out yourself, you can use a simple formula. Remember the formula we talked about before? Amps equals Watts divided by Volts. Most homes in places like the United States have outlets that are 120 volts.

So, let’s say your dehumidifier’s power is 240 watts. You’d do the math like this: 240 watts divided by 120 volts equals 2 amps. This means your dehumidifier uses 2 amps of electricity.

Here’s a step-by-step way to do it:

  1. Find the watts your dehumidifier uses. It’s usually on the back or bottom of the dehumidifier.
  2. Know your home’s voltage. It’s usually 120 volts in many countries.
  3. Use the formula: Amps = Watts / Volts.

For example, if you have a dehumidifier that uses 480 watts, and your home voltage is 120 volts, the math would be like this: 480 watts / 120 volts = 4 amps. So, this dehumidifier uses 4 amps.

How much power does a 50-pint dehumidifier use?

A 50 pint dehumidifier typically uses about 550 watts of power. Using the formula Amps = Watts / Volts, and assuming the standard home voltage is 120 volts, you can calculate the amperage.

So, it would be 550 watts divided by 120 volts, equaling approximately 4.58 amps. This means a 50 pint dehumidifier uses around 4.58 amps of electricity when running.


What is the average amp usage for most home dehumidifiers?
Most home dehumidifiers use between 3 to 7 amps, depending on their size and how much moisture they remove from the air.

Can I plug a dehumidifier into a standard outlet?
Yes, you can plug a dehumidifier into a standard outlet. Most dehumidifiers are designed for standard 120-volt outlets and have amp usage within safe limits for household circuits.

Does the amp usage of a dehumidifier affect my electricity bill?
Yes, the amp usage indicates how much electricity the dehumidifier consumes. Higher amp usage can lead to higher electricity bills, especially if the dehumidifier runs frequently.

How can I reduce the amp usage of my dehumidifier?
To reduce amp usage, select a dehumidifier with an Energy Star rating for efficiency, use it only when necessary, and maintain it regularly to keep it running efficiently.

Will using a dehumidifier with higher amp usage dry the air faster?
Not necessarily. The drying speed depends on the dehumidifier’s capacity and the room’s humidity level, not just the amp usage. Higher capacity dehumidifiers can remove moisture more quickly but may use more amps.
