10 Best Energy Efficient Dehumidifier

The Meaco MeacoDry Arete® Two 12L Dehumidifier & HEPA H13 Air Purifier is a versatile product designed for those who need both a dehumidifier and an air purifier in one unit. Its standout feature is its energy efficiency, consuming only 3p per hour, making it an economical choice for regular use. The 12-liter capacity is suitable for small to medium spaces, such as homes with up to two bedrooms, and its quiet operation at 38dB makes it a good fit for noise-sensitive environments. With smart control features, it can be operated via the Meaco app or voice commands through Alexa and others, adding convenience.

The device also excels in air purification, utilizing a H13 HEPA filter to remove 99.95% of nano particles, which is beneficial for allergy sufferers. For those interested in drying clothes indoors, the product offers a dedicated laundry mode, touted to save costs compared to a tumble dryer.

The coverage area is limited to 50 square meters, which may not be sufficient for larger homes. At 11 kilograms, its portability could be a concern for some, although it's manageable for most users. The product's design, including an adjustable speed control and an automatic shutoff feature, adds to its user-friendliness. With a 5-year warranty, it provides peace of mind, and customer feedback is positive, with a 4.7 out of 5 stars rating. This combination of features makes it an excellent choice for someone looking for a quiet, energy-efficient dehumidifier with added air purification capabilities in a small to medium-sized living space.

The Pro Breeze 20L OmniDry WiFi Dehumidifier is a strong choice for anyone looking to control dampness in a home with an energy-efficient, smart device. It can remove up to 20 liters of moisture daily, making it suitable for medium to large rooms such as living areas, bathrooms, or garages. Its energy-saving features, like the automatic humidity sensor and an auto shut-off system, help keep running costs low — reportedly around 7p per hour. The dehumidifier is also praised for being very quiet at under 38 decibels, so it won’t disturb your sleep or work.

Portability is another plus here: it’s compact for its capacity and comes with wheels, making it easy to move around. The 4-liter water tank is fairly large, reducing how often you need to empty it, and you also get a continuous drainage option via a removable hose if you prefer. The included digital LED display and 24-hour timer offer flexibility, letting you set it to run only when you want. Plus, the smart app and voice control compatibility add convenience, allowing you to manage settings from your phone or with Alexa and Google Home.

On the downside, the dehumidifier uses about 1000 watts, which is typical for this capacity but still something to consider if you want the absolute lowest power usage. Some users might find the water tank size a bit small for continuous use without the hose connected. Also, while it’s compact for a compressor model, it is taller than many smaller units, so space could be a concern in very tight spots. This model is well-suited for those who want an effective, energy-conscious dehumidifier with smart features and quiet operation, especially in medium-sized rooms. It balances performance and convenience well, though very small rooms or users seeking ultra-low power devices might look elsewhere.

The MeacoDry Arete One 10L is a smart choice for smaller homes or flats looking for an energy-efficient dehumidifier that also purifies air. It removes up to 10 liters of moisture per day, which is suitable for spaces up to 42 square meters, making it ideal for bedrooms, small living rooms, or damp-prone areas. One standout feature is its built-in medical-grade H13 HEPA filter, which helps clear dust, pollen, and allergens, improving overall air quality alongside humidity control.

Energy efficiency is a strong point here, with low power consumption translating to about 3p per hour of running costs. This makes it practical for daily use without worrying about high electricity bills. It also has a dedicated laundry mode that runs for six hours to help dry clothes indoors more effectively and cost-efficiently than tumble drying. The unit runs very quietly at 35 decibels, quieter than many similar devices, so it won’t disturb you during sleep or work. Portability is decent with hidden castors and a carry handle, though at around 10.7 kg, it’s not ultra-light but still manageable to move around.

The water tank holds 2.5 liters and is front-loading, which is convenient. The smart humidity mode and adjustable speed add helpful customization to suit different environments. A generous five-year warranty provides extra peace of mind, which is rare among domestic dehumidifiers. This model is excellent for anyone wanting an energy-saving, quiet, and multi-functional dehumidifier for smaller spaces, especially if air purification and laundry drying features are valued.
