Understanding Dehumidifier Energy Consumption
The amount of electricity a dehumidifier uses depends on its wattage and how long it remains operational. When considering energy consumption, it is important to understand the factors that contribute to power usage, as well as how to optimize energy efficiency.
Dehumidifiers generally have an average wattage of 483 watts, which can give an indication of their power consumption. However, it’s essential to note that the actual energy usage can vary based on the specific model and its settings.
One way to gauge energy efficiency is by looking at the energy efficiency rating of the dehumidifier. Energy Star certified models are the most energy-efficient, using approximately 15% less energy than non-certified models. By choosing an Energy Star rated dehumidifier, you can reduce electricity consumption and potentially lower your energy costs.
Another factor to consider is how long the dehumidifier remains operational. If left running for 24 hours, a dehumidifier with an average wattage of 483 watts can use around 11.59 kilowatt-hours (kWh) of electricity per day. It is worth noting that the actual energy consumption may be lower if the dehumidifier is used intermittently or at lower settings.
Optimizing Energy Efficiency
To optimize energy efficiency and minimize electricity usage, there are a few tips to keep in mind. Firstly, it is crucial to select a dehumidifier that is the right size for your space. A dehumidifier that is too small may struggle to effectively remove moisture, leading to longer running times and higher energy consumption. On the other hand, an oversized dehumidifier may use more power than necessary.
Additionally, upgrading to an Energy Star rated dehumidifier can significantly reduce energy usage. These models are designed to operate efficiently while still effectively removing excess moisture from the air. Running the dehumidifier only when necessary, such as during periods of higher humidity, can further help lower energy costs.
In conclusion, understanding dehumidifier energy consumption requires considering the wattage, energy efficiency, and duration of use. By selecting the right-sized dehumidifier and opting for an Energy Star certified model, you can reduce electricity usage and potentially save on energy costs.

Monthly Cost of Running a Dehumidifier
The monthly cost of running a dehumidifier can vary based on factors such as wattage, energy efficiency, and the price of electricity in your area. Understanding these factors can help you make an informed decision and manage your energy costs effectively.
Dehumidifiers typically have wattage ratings that range from 300 to 800 watts, with the average wattage being around 483 watts. To calculate the daily energy usage, multiply the wattage by the number of hours the dehumidifier is left on. If the dehumidifier is running for 24 hours, it can use up to 11.59 kilowatt-hours (kWh) per day.
The cost of electricity varies depending on your location, but on average, the price per kWh in the United States is around $0.13. Using this average price, the monthly cost of running a dehumidifier for 24 hours a day can range from $58.42 to $117. Keep in mind that these figures are estimates and can differ based on your specific situation.
To reduce energy costs, consider investing in an energy-efficient dehumidifier. Energy Star certified dehumidifiers are designed to consume less energy while still effectively removing excess moisture from the air. In fact, Energy Star models can use up to 15% less energy than conventional dehumidifiers. This energy-saving feature can significantly impact your monthly electricity bill.
In addition to choosing an energy-efficient dehumidifier, it’s important to right-size your unit. Selecting a dehumidifier that is appropriate for the size of your space will maximize its energy efficiency.
