Top 5 Energy Efficient Dehumidifiers Review 2021


Frigidaire 50-Pint DehumidifierEditor's Choice

  • Coverage area: up to 4,500 sq. ft.
  • Dehumidification performance (pints per day): 50
  • Water tank capacity: 2 gal.
  • Dimensions: 12.2 x 16 x 24.3 inches
  • Warranty: 1-year limited; 4-year limited on the sealed system

More features: low-temperature operation; top handle, side handles, and caster wheels

If you are looking for the best energy-efficient, quiet dehumidifier, then this is the model for you. It has a large overall coverage area, though it isn’t quite as large as some other models. In fact, it is one of the most versatile models because of its size. It is small enough to go into a bedroom, yet has enough moisture removal power to handle a large wet space like a basement. The large capacity tank is perfect for anyone that doesn’t want to empty a tank all the time.

This dehumidifier is also one of the most portable models on the market today. This portability is due to two different factors. The first, obviously, is the easy-to-roll casters on the bottom. Secondly, this model has handles on both the sides and top, which make it easy to carry or pull into position.

Though it might not seem like such a portable and small dehumidifier would not have that high of a performance level that is not the case with this model. It can remove up to 50 pints of moisture from the air per day. While this isn’t the highest on the market, it is especially beneficial when it comes to energy efficiency. This 50 pint dehumidifier only uses about half the amount of electricity as a 70-pint model.

One thing that you will need to keep in mind with this unit is that its hygrometer is not always completely accurate. It tends to over dehumidify a space so that even if you set it for a humidity percentage of 50, it might actually keep running until it reaches 45%.

What stands out?

  • Very quiet
  • Large coverage area
  • Large capacity tank
  • Easy to move
  • Long warranty
  • High-performance level

What cons did we manage to find?

  • Inaccurate hygrometer

Haier has long been one of the leaders when it comes to dehumidifiers, and this model is no different. Its small size and impressive coverage area make it ideal for use in basements. Something else that makes this such a good choice for use in a basement is the fact that it has two different indicators to tell you that the tank is full.

Since basements usually have the highest humidity levels in a home, you will want to make sure that your dehumidifier is running as often as possible. This model has both an indicator light and an alarm that will go off every few minutes or so to let you know that it is full. These indicators are good attention-grabbing tactics that will help to remind you to empty the dehumidifier when needed, so that it can run as efficiently as possible. However, with its almost one-gallon water tank you won’t have to do it too often.

The other big thing that you need to look for in a dehumidifier for a basement is whether the filters are easy to remove and clean. This is because a dehumidifier in a basement is going to be used much more heavily than models in other parts of a house. The Hair 30-pint dehumidifier’s filters are incredibly easy to access, and also very simple to clean.

One negative factor that makes this dehumidifier better for use in a basement is its noise level. It is unfortunately relatively loud, which means that you will not want to have it around you all the time. Thankfully, if you get it for your basement, you won’t have to listen to it as much as you would in your living room or bedroom.

What stands out?

  • Portable
  • Easy-to-access filter
  • Full tank indicator light and alarm
  • Easy-to-read display
  • Large coverage area

What cons did we manage to find?

As you would expect from a model with such a high-performance level, this dehumidifier is perfect for larger spaces. This dehumidifier has an easy to read display, which is very easy to operate. It is a bit heavy, however, so you might pick a spot for it to stay once you have it in place. It is also a bit loud, so it probably is not the best option for use in a bedroom. Thankfully, it has such a large coverage area that as long as you leave the doors open in your home, it should be able to clear all of the air in your home of as much moisture as you need it to.

The air filters are very easy to access. This makes them simple to clean as well. The water tank, on the other hand, is much more difficult to remove. In fact, you will have to be really careful when you put it back in place, as it has a tendency to get stuck on the way in and out. Thankfully, as long as you keep this in mind, it shouldn’t be too big of an issue.

  • User-friendly display
  • Easy-to-clean filters

As you would expect with most home appliances, dehumidifiers are usually very expensive. This is because in most cases they are very large pieces of equipment that come with a price tag to match. Some models are so expensive that you might feel like you can’t find one that will fit your budget. Thankfully, this model from Pro Breeze is exceptionally budget-friendly. It is also quite small, so it’s an ideal dehumidifier for a bathroom, closet, crawl space, or even an RV. Since it is so cheap and compact, it is perfect for someone who wants to dehumidify a smaller space without having to spend a ton of money.

This dehumidifier is also one of the most portable that you could purchase. It is very lightweight and small enough that pretty much anyone could carry it anywhere, even if you want to take it upstairs. This dehumidifier is also very quiet. It is so quiet, in fact, that you could even use this dehumidifier for a bedroom without even noticing it.

Of course, as you would expect with a dehumidifier that is so small, it has a very small tank. It means that you will have to empty it a lot, which could be a bother. Thankfully, when it does fill up, this dehumidifier will shut down automatically. It also has a very low-performance level. Since it has such a low moisture removal ability, this dehumidifier would not be good for use in extremely moist environments and is better suited for light duty dehumidification.

What do we love it for?

  • Budget-friendly
  • Very compact
  • Easily portable
  • LED indicator for full tank
  • Extremely quiet

Things to Consider

In this section, we will guide you through everything you need to know to find the best energy efficient dehumidifier for your particular needs.

Features to consider while choosing an energy-efficient dehumidifier

As you can imagine, there are several different factors that you need to take into account when you are looking the best energy efficient dehumidifier. In this section, we will go through all of the key components you need to think about before you make your final purchase.

Coverage area

Depending on how large of a space you want to remove the moisture from will help you to choose the right dehumidifier. If you have a large space to work with, then you will need a bigger model, like the LG Energy Star PuriCare 70-Pint Dehumidifier. On the other hand, if you are only thinking about a small space, like your bedroom, then you can probably save some money and get the Pro Breeze Electric Mini Dehumidifier.

Dehumidification performance

The performance level of your dehumidifier should be based on how humid your home is. If you have a very humid house, then you will need a model that can take out tons of moisture each day, like the Ivation 70 Pint Energy Star Dehumidifier. Just be sure that you don’t get the performance and tank capacity mixed up, as most machines will fill their tanks more than once during the day, especially if they are being used in a really humid place.

Energy Star certification

Since we are talking about energy efficiency, we need to mention the Energy Star certification. This certification shows that an appliance, in this case, a dehumidifier, fits the government standards for energy efficiency. The models that have met these specifications are guaranteed to save you money, and, fortunately, all the models listed here are Energy Star certified, apart from the Pro Breeze Electric Mini Dehumidifier which instead boasts an energy efficient 25W ETL-certified adapter.

Water tank capacity

1397836122922The capacity of the tank on your dehumidifier is going to be one of the most significant factors in determining how much moisture you can remove from the air each day. Since most tanks are smaller than the performance level of the dehumidifier, the tank will need to be emptied several times a day. If you don’t want to empty all that often, you can go for a larger tank size, like the two-gallon tank you get with the Frigidaire model.


The number of modes or speeds that you can utilize on your dehumidifier will have a direct effect on how energy efficient it can be. Faster speeds will use more electricity, but they will also remove more moisture. Slower speeds are better at saving money since they don’t work quite as hard.

Timers are an excellent setting to look for since it will give you the ability to decide when and for how long your appliance will run. This will help to make operating your dehumidifier much more efficient. The Ivation 70 Pint Energy Star Dehumidifier, for instance, has this handy feature.

Continuous drain option

By getting a dehumidifier that can be drained continuously, you can get around the issue of having to empty the tank all the time. Of course, this will only work if you have a drain nearby to let the dehumidifier drain into. The last thing you want is a mess on your floor because your model isn’t properly draining.

Dimensions and weight

Unfortunately, the larger the space you want to dehumidify, the larger your dehumidifier is going to have to be. Of course, if you are looking to dehumidify a smaller space, you can usually get by with a smaller model like the Pro Breeze Electric Mini Dehumidifier. Before you make your final decision for your dehumidifier, you should make sure you have a spot large enough to accommodate the model you want, since you cannot have it against the wall.


No matter what kind of an appliance you are buying, you need to look for a good warranty. That way, if some part should fail, you will be covered without having to spend any extra money.

Just be careful, as lots of companies will say that they offer a long warranty, but it will only cover certain parts.

Extra features

There are two key features that are really useful to have when it comes to an energy efficient dehumidifier. The first is an auto shut-off system. That will help to make sure that your dehumidifier doesn’t overflow when the tank is full. The second is an indicator light to tell you when the tank is full. That way, you won’t think your unit is still working when it is in fact full.

Tips on how to reduce energy bills when using a dehumidifier

Most of the time, you are going to be running a dehumidifier during the warmer months. This is when humidity is at an all-time high for the year. Since this excess moisture can raise the temperature by quite a bit, it can put an extra strain on your home cooling system. By adding a dehumidifier, you can help your air conditioner to run more efficiently, which will help to reduce your overall energy costs.

Another way to save money when using a dehumidifier would be to make sure that it doesn’t run all the time. Though you want to reduce the humidity in your home, you don’t need it to be zero to start getting some relief. Instead, set your dehumidifier at about 50 or 60%. This will be enough to make your home more comfortable, without overtaxing your appliance. You should also make sure to clean the filter and tank out regularly, as this will help your dehumidifier to run smoothly and prevent overheating.


Usually, yes, the higher the dehumidification rate, the bulkier the appliance is. However, some models are much more compact than others featuring the same dehumidification performance. For instance, the Ivation 70 Pint Energy Star Dehumidifier is a relatively small model overall, but it has a large internal coil section to remove up to 70 pints of moisture per day.

At a minimum, the filter on your dehumidifier should be cleaned at least once a month. If, however, your model runs almost continuously because you are operating it in a really moist environment, then you will want to clean the filter more often.

The biggest benefit that the most energy efficient dehumidifier will bring to the table is the reduction of allergens in your home. Since dust mites, mold, and mildew need moisture to survive, you can cut down on these by reducing the humidity in your home. Dehumidifiers also make the air much cooler, which helps to limit the spread and growth of germs.

Our Verdict

If you are looking for the best energy efficient dehumidifier, then you need to check out the Frigidaire 50-pint Dehumidifier. It has a large coverage area, high-performance level, is extremely energy efficient and easy to use. It is a perfect choice for anyone that wants to save as much money as possible on their energy prices while still removing a ton of moisture from their air. We highly recommend that you give it a try.

Basements are one of the toughest places to get to the right humidity level since they are underground. The Haier HEN30ET is an excellent option to dehumidify a basement, thanks to its full tank indicators and high-performance level.

While most 70 pint dehumidifiers are not that energy efficient, the Ivation 70 Pint Energy Star Dehumidifier, is an exception. If you are looking to remove a lot of moisture from your home while still saving money on your energy bills, this is a great option.
