10 Best Energy Star Dehumidifiers

The MeacoDry Arete Two 10L is a 2-in-1 dehumidifier and air purifier designed for homes and flats up to around two bedrooms in size. It removes up to 10 liters of moisture per day, effectively tackling dampness, mold, and condensation. The unit runs on 151 watts with an estimated cost of just 3p per hour, making it economical for daily use. Noise-wise, it operates quietly at only 35 dB—about half as loud as many competing models—and a night mode further dims lights and reduces noise for undisturbed overnight operation.

The dehumidifier features a 10-liter tank, reducing the frequency of emptying. Smart controls are available through the Meaco app and voice assistants like Alexa and Google, enabling easy setting of target humidity levels and remote monitoring. It also includes a unique humidity display showing both current and target humidity at a glance, along with a laundry mode that efficiently dries indoor washing while saving energy compared to tumble drying.

Weighing around 10.7 kg and standing about 47 cm tall, the unit is somewhat bulky and may be less convenient to move frequently. It offers adjustable speed control and automatic shutoff but does not have advanced drainage options like continuous drainage, which could be a consideration for users seeking a fully hands-off experience. This model is well suited for those who want a multifunctional, energy-saving dehumidifier with smart features and quiet operation, ideal for everyday home use where air quality and moisture control are priorities.

The MeacoDry Arete® One 10L is a solid choice for smaller homes or flats needing a reliable dehumidifier that also purifies the air. It removes up to 10 liters of moisture daily, which suits spaces up to about 42 square meters. This model stands out with its energy-efficient design, using only 151 watts and costing roughly 3p per hour to run, making it economical for everyday use. A key plus is its quiet operation at just 35 decibels—much lower than many competitors—so it won’t disturb your living space. The 10-liter tank is reasonably sized and front-loading, with convenient options like an automatic shutoff to avoid spills and a smart laundry mode that aids indoor drying of clothes while saving energy.

It also features a medical-grade HEPA filter, improving air quality by capturing allergens and dust, which adds extra value beyond just dehumidifying. On the downside, the unit weighs about 10.7 kilograms and measures around 48 cm tall, so while it has hidden handles and castors for mobility, it’s not the lightest or most compact option available. The controls include adjustable speed and multiple modes, although some users might find the interface a bit basic compared to higher-end models.

The product offers an impressive five-year warranty, providing long-term peace of mind. For those seeking a quiet, energy-saving dehumidifier with air-purifying benefits and solid capacity for a small to medium room, the MeacoDry Arete One is a thoughtful, user-friendly pick with only minor trade-offs in size and weight.

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.
