How Much Does it Cost to Run a Dehumidifier

Dehumidifiers are used to reduce excess humidity. Also, prevents problems like mold, mildew, and musty odors. You may also decide to use a dehumidifier to maintain a comfortable indoor environment. But before investing in a dehumidifier, it’s crucial to consider the potential operating costs. In this article, we will explore the factors that affect the cost of running a dehumidifier. After completing this article, you will be able to budget effectively. So, know how much does it cost to run a dehumidifier.

Cost to run a dehumidifier: Factors affecting dehumidifier energy consumption

  • Types
  • Capacity
  • Operating Conditions
  • Duration of use
  • Energy efficiency
  • User settings

Dehumidifiers come in many varieties, including desiccant and compressor-based units. Compressor-based dehumidifiers typically use more energy than desiccants. Also, the size of a dehumidifier determines its capacity. So it can understand how much moisture it can remove from the air in a given period. Comparatively larger capacity units consume more energy.

The energy consumption of a dehumidifier depends on the humidity level. And it is affected by the ambient temperature of the area in which it is operating. High humidity and temperature make the unit work harder and therefore consume more energy. How long you run the dehumidifier each day significantly affects its energy consumption. If it works for a long time, it will consume more energy. You can look for dehumidifiers with an Energy Star rating or other energy-efficient certification to save on energy costs. Having an Energy Star rating will enable better results and use less cost.

Some dehumidifiers are designed with adjustable settings such as fan speed and humidity level. Adjustable settings can affect energy consumption. The low fan speed and humidity settings are ideal for reducing energy use.

Important steps in estimating the cost of running a dehumidifier

  • Determine Power Rating
  • Daily Energy Consumption
  • Electricity Rate
  • Calculate Daily Cost
  • Monthly Cost

Find the dehumidifier’s power rating, typically measured in watts (W). This information can be found on the appliance’s label or in the user manual. Calculate the daily energy consumption in kilowatt-hours (kWh) using the formula:
Daily kWh = (Power rating in watts / 1000) x Operating hours per day.
Check your electricity bill for the cost per kWh. It is usually stated in cents or dollars. Multiply the daily energy consumption (kWh) by the electricity rate (per kWh) to find the daily operating cost.
Daily Cost = Daily kWh x Electricity Rate
To determine the monthly cost, multiply the daily cost by the number of days the dehumidifier will be used in a month.
Monthly Cost = Daily Cost x Number of days in a month


Q: Do dehumidifiers use a lot of electricity?

A: Electricity consumption of dehumidifiers varies depending on their size, capacity, and usage patterns. The power consumption of a dehumidifier is usually measured in watts (W) or kilowatts (kW). A dehumidifier for a single room typically consumes about 300-800 watts per hour. On the other hand, whole-house dehumidifiers can consume 1000 watts or more per hour. Such as Electricity Usage (in kWh) = Power Rating (in kW) x Operating Hours.

Q: Do dehumidifiers save money?

A: Dehumidifiers can potentially save money in certain situations. But it consumes energy depending on usage and humidity. But there are some situations where dehumidifiers can save money.

Q: How much does it cost to run a dehumidifier for 1 hour?

A: The power consumption is usually measured in watts (W) or kilowatts (kW). You can find this information on the dehumidifier’s label or in its user manual. Or Electricity rate: The cost of electricity varies based on your location and the provider. It is typically measured in cents per kilowatt-hour (kWh).

Q: How much does it cost to run a dehumidifier 24 hours a day?

To find the daily cost of running the dehumidifier, multiply the daily energy consumption (in kWh) by the electricity rate (in $/kWh). Using the $0.15 per kWh rate, the daily cost would be 12 kWh x $0.15/kWh = $1.80.

Q: How much does it cost to run a dehumidifier for a month?

A: Monthly cost = Monthly energy consumption (kWh) x Electricity rate (cost per kWh)
Monthly cost = 150 kWh x $0.15/kWh = $22.50. It’s just an example.

Final words

Now you know, how much does it cost to run a dehumidifier? So consider the right model to run a dehumidifier. The cost of running a dehumidifier depends on various factors so there is no need to worry about its cost. A good user can keep costs under control by choosing a dehumidifier with settings. By understanding the above and using the estimation guidelines provided, you can budget to manage energy costs. Remember, choosing an energy-efficient dehumidifier can help reduce your overall electricity costs in the long run.
