10 Best Energy Star Dehumidifiers 2025 in the UK

The Pro Breeze 30L/Day Smart Dehumidifier is a noteworthy choice for those tackling serious dampness and condensation challenges. It can remove up to 30 liters of water per day, making it suitable for larger areas like basements or bathrooms. Its energy efficiency is a big plus, as it's been recommended by Which magazine for its low energy consumption, which is crucial for continuous use without hefty utility bills.

In terms of usability, the digital humidity display and smart app control offer convenient operation, letting you monitor and adjust settings remotely. This includes setting a target humidity level and scheduling operations, which can save energy by automating its functions. The inclusion of a continuous drainage option means you won't have to manually empty its 3-liter water tank frequently, though some may find the tank size on the smaller side given the maximum capacity.

Portability is another strength, thanks to its compact size and easy-glide wheels, making it simple to move between rooms. However, weighing 7.71 kg, it might be slightly cumbersome for some users when lifting. The noise level isn't explicitly mentioned, but its energy-efficient design suggests it's likely quieter than older models. An automatic humidity sensor and auto-defrost function provide further convenience, helping maintain consistent performance in varying conditions. This dehumidifier is well-suited for residential use, particularly in areas with significant moisture issues. Users who need a larger tank or specific noise-level requirements might need to consider additional options.

The Pro Breeze OmniDry WiFi 20L Dehumidifier is designed to handle moisture issues in homes, garages, and bathrooms efficiently, with a strong capacity of 20 liters per day. Its low energy consumption, with a cost as low as 7p per hour, makes it an economical choice for continuous use. The ultra-quiet operation (less than 38dB) ensures it won't disturb your daily activities or sleep.

The compact size and portability, enhanced by four wheels, make it easy to move and fit into smaller spaces. The dehumidifier features an automatic humidity sensor and a digital LED display, allowing users to set and monitor their desired humidity levels between 30-80%. This smart feature conserves energy by shutting off once the desired level is reached. The large 4-liter water tank and continuous drainage option mean less frequent emptying, which is convenient for long-term use.

Additionally, the device includes a 24-hour timer and three operation modes—auto, continuous, and sleep mode—catering to various needs. However, some might find the 13.6 kg weight somewhat cumbersome despite its portability features. Moreover, the device's reliance on a 1000-watt compressor could be a concern for those particularly sensitive to power usage. For those seeking a balance of energy efficiency, quiet operation, and smart functionality, this dehumidifier is a solid choice.

The MeacoDry Arete One 12L is a versatile dual-function dehumidifier and air purifier designed for regular-sized homes. It effectively removes up to 12 liters of moisture per day, which is helpful for preventing dampness and condensation. A key strength of this device is its energy efficiency, offering low running costs which makes it cheaper to operate, especially with features like the energy-saving laundry mode. This mode is particularly useful for drying clothes indoors more economically than using a tumble dryer.

Another prominent feature is its ultra-quiet operation at 35dB, making it suitable for night use without causing disturbances. This is complemented by its intelligent design that includes hidden castors for easy mobility, a cable tidy, and a straightforward front-loading 2.5-liter water tank that simplifies maintenance.

The integrated H13 HEPA filter significantly enhances indoor air quality by removing allergens and fine particles, which is a bonus for anyone with allergies or asthma. The unit's design is compact enough for easy placement in various areas around the home, and its size and portability make it practical for both residential and some commercial use. However, the 12-liter daily capacity might be on the lower side for larger homes or very damp environments where higher capacity dehumidifiers might be more efficient. Additionally, while the device is energy-efficient, the relatively small tank may require frequent emptying unless a continuous drainage option is available.

Its five-year warranty offers peace of mind, indicating confidence in durability from the manufacturer. This product is an excellent choice for someone seeking a quiet, efficient solution for maintaining optimal humidity and air quality in a moderately-sized space.
