Many people ask, “Does a dehumidifier use a lot of electricity?” This is an important question. Dehumidifiers help remove moisture from the air. They make homes more comfortable and help stop mold and mildew. But, some worry about the cost of running them.
What Is a Dehumidifier?
A dehumidifier is a small machine. It takes moisture from the air. When the air is too wet, it can cause problems. Wet air can make your home feel sticky and cold. It can also cause bad smells and damage furniture.
Dehumidifiers help fix this by pulling water from the air. They collect the water in a tank or send it out through a drain. This makes the air dry and clean.
How Does a Dehumidifier Work?
A dehumidifier uses electricity to work. It has a fan that pulls air inside. Then, the air goes over cold coils. Water in the air turns into drops. The machine collects these drops in a tank.
After that, the dry air goes back into the room. The machine keeps doing this until the room is dry enough.
How Much Electricity Does a Dehumidifier Use?
The amount of electricity a dehumidifier uses depends on many things. Some important points are:
- The size of the dehumidifier: Bigger machines use more power.
- How often it runs: If it runs all day, it uses more electricity.
- The moisture level in the room: More moisture means the machine works harder.
- The temperature of the room: Cooler rooms make the dehumidifier work more.

Electricity Use Compared to Other Home Appliances
How much electricity does a dehumidifier use compared to other devices? Here is a simple table showing average power use:
| Appliance | Average Power Use (Watts) | Approx. Daily Use (kWh) |
|---|---|---|
| Dehumidifier (medium size) | 300-500 Watts | 1.2 – 3.6 kWh |
| Air Conditioner (small room) | 1000-1500 Watts | 6 – 9 kWh |
| Refrigerator | 100-200 Watts | 1 – 1.5 kWh |
| Microwave Oven | 600-1200 Watts | 0.1 – 0.2 kWh (short use) |
| Light Bulb (LED) | 10 Watts | 0.12 kWh |
As you see, a dehumidifier uses less power than an air conditioner. But, it uses more than a refrigerator or LED light. The exact cost depends on how long you run it.
How to Calculate Electricity Cost of a Dehumidifier
You can find out how much electricity a dehumidifier uses easily. Here is a simple way to calculate:
- Find the power in watts. (Look on the machine label.)
- Multiply watts by hours used per day.
- Divide by 1000 to get kilowatt-hours (kWh).
- Multiply kWh by your local electricity rate.
Example:
A dehumidifier uses 400 watts. You run it 5 hours a day. Your electricity rate is $0.12 per kWh.
Calculation: (400 watts × 5 hours) ÷ 1000 = 2 kWh
Cost: 2 kWh × $0.12 = $0.24 per day
This means you pay about 24 cents a day to run the dehumidifier.
Does a Dehumidifier Run All Day?
Not always. Dehumidifiers have sensors. They stop when the air is dry enough. They start again when moisture comes back.
So, a dehumidifier does not run all the time. It uses electricity only when needed.
Tips to Save Electricity When Using a Dehumidifier
You can save electricity while using a dehumidifier. Try these tips:
- Use the right size: Choose the right size for your room.
- Run it only when needed: Turn it off if the air feels dry.
- Keep doors and windows closed: This helps the machine work better.
- Clean the filter: A clean filter helps the machine use less power.
- Use a timer: Set the machine to run only at certain times.
- Place it well: Put the dehumidifier in the middle of the room.
Energy Efficiency and Dehumidifiers
Some dehumidifiers are more energy efficient than others. Look for models labeled “Energy Star.” These use less electricity to do the same job.
Energy-efficient models may cost more at first. But, they save money over time.

When Should You Use a Dehumidifier?
Use a dehumidifier if your home feels damp. It is good in basements, bathrooms, and kitchens. These areas often have more moisture.
Using a dehumidifier can stop mold growth. Mold can cause health problems and damage your home.
Summary
So, does a dehumidifier use a lot of electricity? The answer: it depends.
A medium dehumidifier uses about 300 to 500 watts. It usually costs less than air conditioning. It does not run all day, only when needed.
You can save electricity by choosing the right size and using it wisely. Energy Star models help save money too.
A dehumidifier helps keep your home healthy and dry. The electricity cost is worth the comfort and safety it brings.
Frequently Asked Questions
Does A Dehumidifier Use A Lot Of Electricity?
Dehumidifiers use moderate electricity depending on size and runtime. Smaller units consume less power than larger ones. Running it continuously will increase electricity use.
How Much Electricity Does A Dehumidifier Consume Daily?
A typical dehumidifier uses about 300 to 700 watts per hour. Running 8 hours a day can use 2. 4 to 5. 6 kWh. Electricity cost depends on local rates.
Can A Dehumidifier Raise My Electric Bill?
Yes, using a dehumidifier often can raise your electric bill. The increase depends on the unit’s power and usage hours. Energy-efficient models help reduce costs.
Do Bigger Dehumidifiers Use More Electricity?
Bigger dehumidifiers generally consume more electricity than smaller ones. They remove moisture faster but need more power. Choose size based on room needs.
