How much electricity does a dehumidifier use? Find out here (based on 573 models). Plus, get details on dehumidifier wattage and see which is the most energy efficient dehumidifier on the market. The following dehumidifier wattage, power consumption and energy efficiency details are based on 573 dehumidifiers.

Spoilers:

The average dehumidifier wattage is 483.24W .

. On average, dehumidifiers use 0.427 kWh of electricity per hour ( 10.24 kWh per day ). ). The most energy efficient dehumidifier (the Midea Cube – get details on Amazon, here , or see the same model with a Pump feature, here ) uses 12.031 kWh per day, while the lowest daily consumption is 5.24 kWh per day (the INNOVATIVE IW-25-4 – see details on Amazon, here ). Continue reading to see 14 of the most energy efficient dehumidifiers on the market along with their energy efficiency rating, daily water removal capacity, wattage, power consumption, square feet covered, and much more.

Dehumidifier wattage

Dehumidifier wattage ranges from 214W to 970W, with 483.24W being the average. The most common dehumidifier wattage is 600W.

This is based on research into the power consumption of 573 dehumidifiers.

The dehumidifier wattage range is quite substantial. There’s a 756W difference between the low and high end of the range. This is because there’s a considerable difference between the performance of modern energy efficient dehumidifiers and older models. Let’s break down the wattage range into low, medium and high, and take a brief look at each.

Low wattage dehumidifiers

Low wattage dehumidifiers use between 214W and 466W.

Low wattage dehumidifiers are more modern, energy efficient appliances. Many of these are ENERGY STAR certified. However, not all ENERGY STAR certified dehumidifiers fall within this low wattage range. Some ENERGY STAR certified dehumidifiers consume up to and above 540W. This is because “low wattage” does not mean “energy efficient” – I go into more details about this in the Dehumidifier Energy Efficiency section below. Note: these figures relate to portable dehumidifiers only. These are by far the most commonly used in households. Whole-home dehumidifiers (these require dedicated circuits and cannot be moved) and personal dehumidifiers (these are typically handheld and are not effective at removing moisture from air in a whole room) are not included in these figures.

Medium wattage dehumidifiers

Medium wattage dehumidifiers range between 467W and 700W.

The average wattage (483.24W) and the most common dehumidifier wattage (600W) falls within this category. Most modern dehumidifiers and some ENERGY STAR certified dehumidifiers also fall within this category, albeit at the lower end of the range.

Older dehumidifiers appear frequently in this category too.

High wattage dehumidifiers

High wattage dehumidifiers use between 701W and 970W.

Older household dehumidifiers and industrial units appear most in this category.

It’s also worth noting that, in many cases, medium wattage dehumidifiers can fall within this category too if the wattage is calculated from the voltage and amperage alone. Actual consumption, tested using an energy monitor, tends to be considerably lower than this calculation suggests. A dehumidifier with a high wattage is not always bad, although it’s likely in most cases. This is because wattage doesn’t always relate to energy efficiency. But before we jump into energy efficiency, let’s take a look at how much electricity dehumidifiers use over various durations.

How much electricity does a dehumidifier use?

On average, dehumidifiers use 0.427 kWh of electricity per hour.

The most common amount of electricity that dehumidifiers use per hour is 0.548 kWh. Overall, the amount of electricity that dehumidifiers use per hour ranges from 0.23 kWh to 0.983 kWh. ENERGY STAR certified dehumidifiers use between 0.23 kWh and 0.548 kWh of electricity per hour.

But how much electricity do duhumidifiers use over longer durations?

How much electricity dehumidifiers use per day

Dehumidifiers use 10.24 kWh of electricity per day, on average.

The amount of electricity that dehumidifiers use ranges from 5.52 kWh to 23.6 kWh per day, with 13.14 kWh being the most common. ENERGY STAR certified dehumidifiers use between 5.52 kWh and 13.14 kWh of electricity per day. These figures assume that the appliance runs continuously for a 24 hour period.

Dehumidifier electricity usage per month

Assuming 30 days of continuous usage, dehumidifiers use 307.2 kWh of electricity per month, on average. The most common amount of electricity used by a dehumidifier per month is 394.2 kWh. But is this a lot? Before we get to this let’s look at how / where dehumidifiers use electricity.

Dehumidifier energy use

Dehumidifiers use various amounts of energy when active. They cycle through different stages, activating different components, when removing moisture from the air. They may also enter standby mode when a certain moisture level is reached.

The refrigeration coil, fan, compressor and standby mode consume different amounts of energy. Humidity level of a room also impacts energy usage – the higher the humidity, the more power is used. In order to get accurate energy usage assessments, the hourly, daily and monthly electricity usage figures noted above assume continuous usage over a 24 hour period.

This captures the various energy usage levels over time.

The figures are based on the electricity usage of 573 dehumidifiers. IEF (L/kWh) and daily capacity (more on these below), for the majority of dehumidifiers, were sourced from ENERGY STAR. Older models and best selling models are also included. Now that we know where dehumidifiers use energy and how much electricity a dehumidifier uses, let’s put the consumption into perspective.

Do dehumidifiers use a lot of electricity?

Yes. Dehumidifiers use a lot of electricity.

While the wattage (483.24W is average) and the hourly electricity usage (0.427 kWh is average) are not substantial, the long duration of use results in dehumidifiers consuming a considerable amount of electricity. At up to 23.6 kWh per day, older dehumidifiers can use a substantial amount of electricity. Modern energy efficient dehumidifiers use a lot less electricity, consuming as little as 5.52 kWh per day.

However, this is still quite considerable.

To put dehumidifier electricity usage into perspective, let’s compare the amount of electricity that a dehumidifier uses per day with other household appliances.

Running the most energy efficient dehumidifier for 1 day is equivalent to:

For more context, according to the U.S. Energy Information Administration, the average amount of electricity consumed per month by residential US customers is 877 kWh. Dehumidifiers can account for 19% to a whopping 81% of electricity consumed per month by US households. This assumes 24/7 usage throughout the month. If we assume 8 hours of use per day, dehumidifiers can account for 6.3% to 27% of electricity consumed per month by a typical US household. So, now that we know that dehumidifiers use a lot of electricity, let’s take a look at dehumidifier energy efficiency and identify which dehumidifiers are the most efficient.

Dehumidifier energy efficiency

Energy efficient dehumidifier wattage ranges from 214W to 540W.

However, wattage shouldn’t be used as the sole energy efficiency consideration. This is because wattage doesn’t take into account how effective a dehumidifier is at removing moisture from the air. Energy efficient dehumidifiers remove more moisture from the air per watt compared to standard dehumidifiers.

Energy efficient dehumidifiers use efficient compressors, refrigeration coils and fans.

They’re usually ENERGY STAR certified, which typically consume close to 15% less energy than standard dehumidifiers, while still achieving the same or better results. ENERGY STAR certified dehumidifiers use from 5.52 kWh to 13.14 kWh of electricity per day. Integrated Energy Factor and Capacity are key energy efficiency factors. Let’s take a look at these in more detail.

Energy efficient dehumidifier IEF (L/kWh)

Integrated Energy Factor, IEF for short, is a key performance metric for dehumidifiers. Reported in liters per kWh (L/kWh) consumed, IEF is a measurement of dehumidifier energy efficiency.

L/kWh is commonly used instead of IEF.

Dehumidifiers with a higher IEF or L/kWh are more efficient.

The higher the IEF or L/kWh, the more moisture is removed from the air per watt consumed.

So now for the figures, sourced from 502 ENERGY STAR certified dehumidifiers.

Energy efficient dehumidifiers have an IEF (or L/kWh) that ranges from 1.57 to 1.95, with the average being 1.79.

The most common IEF (or L/kWh) is 1.8 for energy efficient dehumidifiers.

Now let’s take a look at Capacity.

Daily moisture removal capacity for energy efficient dehumidifiers

Dehumidifier Capacity is another energy efficiency factor.

This is a measurement, in pints, of how much moisture can be removed from the air over a 24 hour period.

The higher the capacity, the more effective the appliance.

Capacity, often referred to as Product Capacity or Moisture Removal Capacity, is not to be confused with bucket or tank capacity, which simply refer to how much water the dehumidifier can hold before it needs to be emptied. Let’s take a look at the figures for Capacity (again sourced from 502 ENERGY STAR certified dehumidifiers). To rephrase this:

How much water should a dehumidifier remove in a day?

Energy efficient dehumidifiers remove between 20.04 pints and 50 pints of water from the air per day. On average, per day, energy efficient dehumidifiers remove 39.09 pints of moisture from the air, however, 50 pints is most common. Combining Capacity and IEF (or L/kWh), identified under standardized test conditions, helps identify the most energy efficient dehumidifiers.

This is more effective than using wattage as the sole energy efficiency factor.

So which dehumidifiers are the most efficient?

Energy efficient dehumidifiers

More than 117 ENERGY STAR certified portable dehumidifiers have an IEF (L/kWh) of 1.9 or higher – 1.95 is the highest. However, whole-home dehumidifiers can achieve an IEF (L/kWh) of up to 2.35. These require professional installation and cannot be moved. When referring to dehumidifiers, most people are referring to portable dehumidifiers, which can be easily moved from room to room. For this reason, let’s focus on portable dehumidifiers. There are over 50 dehumidifiers that received the coveted “ENERGY STAR Most Efficient” label. Within these, there are some stand out performers. However, a key energy efficiency factor is matching the right product to your needs. Using unnecessarily powerful appliances results in electricity wastage. So, even the most energy efficient appliance may result in wastage if it’s not suited to your needs. For this reason, I’ll list standout performers that are suitable for various room sizes, which have varying IEF, capacity and power consumption levels. This should help those in the market for an energy efficient dehumidifier to choose the most appropriate model to suit their needs. The table below is a shortlist of 14 of the most energy efficient dehumidifiers. The table is arranged from low to high IEF (the higher the IEF, the better). Again, various IEF ratings, daily capacity, wattage, square footage, etc. are included in this shortlist so you can choose the most energy efficient dehumidifier for your circumstances. For example, if you have a small room then a more powerful dehumidifier, even if it has a better IEF, will be unnecessarily powerful. This, however, can be managed efficiently if the dehumidifier has the ability to automatically maintain humidity levels in a room. This is because a more powerful dehumidifier can reach the appropriate humidity level quicker than less powerful models, and then enter inactive mode. Ultimately, a similar level of power consumption can be achieved by dehumidifiers that have high electricity usage on paper compared to models that consume less electricity.

Final thoughts

Dehumidifiers can use a lot of electricity if you’re not careful.

Running an older dehumidifier all day can, in extreme cases, nearly double the amount of electricity that you use in your home. As a result, it’s important to consider the energy efficiency of your dehumidifier. Reducing the amount of electricity that your dehumidifier uses has the obvious benefit of reducing your electricity bills, while also reducing your carbon footprint. I hope the details above give you some context on the power consumption of dehumidifiers and enables you to make more informed purchasing and usage decisions.
