Selecting the best dehumidifiers isn't just about turning them on and seeing how much water they collect. We conducted in-depth evaluations under real-world conditions, focusing on what truly matters to consumers. Here's how we approached our testing:
To assess performance, we measured how effectively each dehumidifier removed moisture from the air in controlled environments with varying humidity levels and temperatures.
By monitoring the amount of water extracted over specific timeframes, we determined their suitability for different room sizes and conditions. Models were tested for their ability to maintain efficiency in both high and low humidity settings, ensuring versatility.
Accuracy was key, so we used hygrometers to verify how well each dehumidifier maintained its set humidity levels. This allowed us to determine consistency and performance in fluctuating conditions, such as seasonal changes or sudden shifts in indoor climate.
Reliable humidity control can make all the difference in comfort and air quality, and our tests prioritised this factor.
Energy consumption was measured during full-capacity operation over 24 hours to understand cost-effectiveness. We compared these findings to energy efficiency ratings, ensuring the units balanced performance with affordability.
Models with energy-saving features, such as auto-shutoff and eco-modes, scored higher for their ability to keep running costs low.
We tested noise output across different fan speeds and modes using decibel meters, recording sound levels at various distances. This helped determine whether the units were quiet enough for use in bedrooms, offices, or other noise-sensitive environments.
Models with whisper-quiet modes or low-noise operations stood out for their unobtrusive performance.
To evaluate usability, we explored how intuitive the controls were, the simplicity of setup, and the convenience of features like tank removal and continuous drainage. We also examined the clarity of the manuals, checking for clear instructions and troubleshooting support.
Products that prioritised user-friendly designs were highly rated for their accessibility.
Mobility and design were tested by examining the weight, size, and inclusion of features like wheels and handles. We evaluated their adaptability across various room sizes and layouts, ensuring practicality for everyday use.
A compact yet sturdy design was often a deciding factor in our rankings, especially for smaller living spaces.
Durability and ease of maintenance were assessed by inspecting tank removal, cleaning processes, and filter accessibility. We tested how well each model resisted wear and tear over time, particularly in environments prone to dust, pet hair, or heavy usage.
Regular maintenance shouldn't be a hassle, and the best models make this process straightforward.
For units with extra features like drying laundry modes, timers, smart connectivity, or air purification, we thoroughly tested their functionality. Smart features, including app connectivity and remote control, were evaluated for practicality and user-friendliness.
Added benefits like HEPA filters or eco-friendly refrigerants provided bonus points for enhancing the overall experience.

UK homes frequently benefit from dehumidifiers due to the country's damp climate, which leads to excess moisture, condensation, and mould growth. A dehumidifier helps maintain healthy humidity levels (typically 40-60%), preventing structural damage, protecting furnishings, and improving indoor air quality. They are especially valuable in poorly ventilated spaces like basements, bathrooms, and older properties prone to dampness.
Modern dehumidifiers in the UK are generally energy-efficient, with running costs varying by model. Budget-friendly compressor models like the Devola 12L cost approximately 4-5p per hour, while higher-capacity units like the Honeywell 20L cost around 8-9p per hour (based on 24p/kWh electricity rates). Energy-efficient features like auto shut-off, adjustable humidistats, and eco-mode significantly reduce overall consumption. Compared to managing mould damage or running tumble dryers, dehumidifiers offer cost-effective moisture control.
Dehumidifier size depends on room dimensions and moisture severity. For small rooms (up to 15m²) like bedrooms or bathrooms, 10-12L/day capacity is sufficient. Medium spaces (15-30m²) such as living rooms benefit from 12-16L/day models. Large areas (30-50m²) or multi-room coverage require 20L/day capacity or higher. Consider factors like dampness severity, ventilation quality, and whether you'll use continuous drainage for optimal sizing.
Using a dehumidifier during UK winters is highly worthwhile. Colder weather increases condensation on windows and walls as heating systems raise indoor temperatures while outdoor cold prevents natural ventilation. This creates ideal conditions for mould and dampness. Quality dehumidifiers like the Devola and Honeywell models operate effectively down to 5°C, making them suitable for year-round use including unheated spaces. Winter operation prevents condensation damage and maintains comfortable humidity levels despite reduced ventilation.
Drying clothes with a dehumidifier is significantly cheaper than using a tumble dryer in the UK. Dehumidifiers consume 170-355W compared to tumble dryers using 2,000-3,000W. Running a dehumidifier costs 4-9p per hour versus 48-72p per hour for tumble dryers. Models with dedicated laundry modes (like the Honeywell, Devola, and Innvitop) optimize moisture extraction for faster drying. This approach also prevents excess moisture buildup in living spaces, reducing condensation and dampness while saving energy costs.
Hopefully, our guide to the best dehumidifiers in the UK has helped you find the right model for your needs. With so many options, it's not an easy decision, but our top pick is the Hangsun 12L Dehumidifier.
Its efficient moisture removal, adjustable settings, and user-friendly features make it an excellent choice for compact spaces. For larger needs, the Honeywell 20L/Day Dehumidifier and Air Purifier offers great capacity and energy efficiency, while the Devola 12L/day Low Energy Dehumidifier is ideal for those on a budget.
One model to avoid is the CONOPU 1000ml Dehumidifier. While compact, its performance falters in larger or cooler spaces, with durability and noise issues that limit its reliability.
