Humidity can make your everyday living experience extremely uncomfortable. In such a case, a dehumidifier seems like a good purchase to make.

However, with all the heavy electronics installed in the house that massively contribute to the power bills, it makes more sense to purchase the most energy-efficient dehumidifier.   

These appliances have 15% low energy consumption, high coverage area, variable fan and temperature settings, and great performance. You can find models for extremely humid to mildly humid regions.

This review will help you determine the best models on the market that are worth your hard-earned money. Let’s start with the top models.

Important Features To Check Before Buying Energy Efficient Dehumidifier

How to Buy the Most Energy Efficient Dehumidifiers

1. Energy Consumption

While searching for the most energy-efficient dehumidifier, it is apparent that your prime focus is centered on its energy consumption. Well, the power consumption is based on the machine’s size and features.

The first rule of thumb is to go with eco-friendly dehumidifiers. The brands clearly mention on the product’s package whether it is eco-friendly or not.

You can also assimilate it from the energy consumption of the product. These appliances could consume from 300 – 500 watts of energy as they operate.

Moreover, finding a product labelled as an energy-efficient unit is not good enough. You need to verify the same. The Energy Star Program US EPA was commenced to determine if the product qualifies for the disposition of an Energy Star product or not.

A product that is tested and approved by EPA consumes 15% less energy than a standard product. You need to focus on models with less energy consumption to successfully get a product that saves you money.  

The Ivation IVALDH70PW comes with energy star certification, making it one of the best dehumidifiers in the league to save on energy costs.

2. Performance

The dehumidifier’s performance should directly relate to the humidity level of the house. If you live in an extremely humid temperature, you will need a product with high performance.

It is determined through pint/day. A model with 70 pints/day is extremely suitable for highly humid homes. Simultaneously, to freshen up your surroundings, 30 pints/day is an appropriate performance level to consider.

3. Coverage Area

The coverage area means the square feet area in which the humidifier delivers its best performance. You can find models with a maximum of 5,000 square feet coverage area to 1,000 square feet on the minimum side.

It should be according to your needs that you select the right model for purchase. For those with larger areas to target, the Vremi dehumidifier is an ideal product with a 4,500 square feet coverage area, and a 1.8-gals tank capacity.

4. Tank Capacity

The next important feature is the tank capacity. The tank helps in storing all the water that your dehumidifier collects from the air. If you live in extremely humid regions, the best decision is to pick a product with a large tank capacity.

You can find the tank capacity between 1 – 3 gals. If you have a small basement with less humidity, then an appliance with a small tank capacity will also suffice. However, the Frigidaire FFAP5033W1 with a 2-gals tank capacity will be perfect for highly humid areas.

Keep in mind, you can find dehumidifiers in different sizes, capacities, and performance levels. The selection should subject to the humidity level in your house for an ideal purchase.

5. Auto Shut-Off

The dehumidifier auto shut-off when the tank is full, to prevent water overflow. This feature comes in handy when you are too busy to constantly check the tank if it is full or not.

Also, these models come with a light that turns on as soon as the tank is full. This way, these appliances do not cause a mess for you to tackle afterwards.

6. Humidity Level Settings

One of the best things about the latest humidifiers is that they allow you to select the room’s humidity level.

These automated machines stop themselves as soon as the room’s humidity level is met. It helps you customize the environment of your room.

7. Warranty

Some brands are very specific in providing after-sale help to the buyers. As a customer, you should also look for products that come with a warranty.

An electronic appliance can get damaged or stop working at any point. With a warranty, you can ensure that company is taking all the charge repairing the damages or replacing the item if it stops working during the warranty period.

Make sure to pick a dehumidifier with a warranty.

Tips to Improve the Energy-Efficiency of your Dehumidifier

Tips to Improve the Energy-Efficiency of your Dehumidifier

There are other ways to improve the energy-efficiency of dehumidifiers:

Closed House Settings

Irrespective of your dehumidifier’s energy efficiency, it won’t work well if there is a constant source of more moisture pouring inside the room.

You can enhance its performance by keeping the windows and doors closed. This way, the dehumidifier will take less time to remove all the pending moisture from the air.

Air Leaks Repair

Window leaks are hidden sources of letting the air make its way inside the house. This will never seal the house to make a humidity-free.

You should check for the leaking windows and ensure that attic ventilation is not upsetting the house temperature.

Right Setting of the Dehumidifier

The appliance should be placed in the house’s most sanitized setting.

If it is exposed to dust and dirt, there is a possibility of clogging that can further reduce the dehumidifier’s efficiency. Therefore, the right placement is very important.

Improve Home Drainage

The drainage can also cause humidity in the house. You need to pay close emphasis on clogged gutters or overwatered gardens that are close to the foundation.

Once the water gets inside, it evaporates and causes humidity.

Sealing the Cracks

If you have foundation cracks, you can expect humidity in the house, especially the basement.

Fixing these cracks will eliminate the chances of moisture developing in the environment and hence prevent the humidity.


No one wants to live in a sticky environment. You can refer to our energy efficient dehumidifier review to find the best model on the list.

The Homelabs HME02003IN is the best overall product with the most resourceful features and stunning looks. This model will help you save a lot of money on energy bills.
