One To Avoid

CONOPU Dehumidifier, 2300ML Dehumidifiers for Home

We gave the CONOPU Dehumidifier a thorough test, and while it has some notable features, it ultimately falls short of expectations. The automatic defrosting and large 78oz tank with auto shut-off are thoughtful inclusions, and the portability (thanks to the handle) is convenient.

Its decorative lighting adds an aesthetic touch (if that’s a priority). However, these positives don’t outweigh the numerous drawbacks. The dehumidification performance is underwhelming, particularly in larger or highly humid spaces.

Even with dual-powered modules, moisture removal is slow and limited (barely making a dent in noticeable humidity). It struggles in low temperatures, and using it in bathrooms or overly damp areas could damage internal components—a significant limitation for a dehumidifier.

Noise levels are another concern. Even in sleep mode, it’s noticeably loud, making it unsuitable for bedrooms or quiet spaces. While the LED display and controls are easy to use, they don’t compensate for the overall lack of efficiency.

Ultimately, this device is best suited for small, lightly damp spaces. If you’re looking for reliable dehumidification or a durable, long-lasting solution, we recommend exploring other options.

How We Evaluated and Chose the Best Dehumidifiers

When it comes to finding the best dehumidifier for under £100, we went beyond simply plugging in the device and observing its function. Instead, we conducted thorough testing to evaluate every aspect that matters. Here's how we approached it:

Performance Testing

We measured each dehumidifier’s ability to remove moisture by placing it in a controlled environment with high humidity (e.g., 70%) and recording its extraction over 24 hours. Results were compared to manufacturer claims to verify accuracy.

Tank capacity and auto shut-off were tested to see how long each unit could run without emptying while ensuring reliable overflow prevention. We also assessed performance across various room sizes, such as bathrooms and bedrooms, and in cold conditions to test features like auto-defrost.

Usability Testing

Ease of use was crucial. We tested how simple it was to set up the dehumidifiers, including connecting drainage hoses when applicable. Noise levels were measured with a decibel meter in standard and sleep modes, ensuring they operated quietly in bedrooms or offices.

Portability was evaluated based on built-in handles, wheels, and weight. The user interface was also checked for clarity, ensuring controls, displays, and humidistats were intuitive.

Energy Efficiency Testing

We used energy monitors to measure the power consumption of each dehumidifier over a 24-hour period during normal operation. This allowed us to determine which models offered the best value in terms of energy usage, particularly for long-term use.

Air Quality Testing

For models equipped with air purification systems, we tested their ability to trap dust and other particles. Using particle counters, we evaluated how effectively these features improved air quality alongside moisture reduction.

Durability and Build Quality

Each unit underwent durability testing over several weeks to observe resistance to wear and tear. The materials were inspected for robustness, and we paid attention to how well the devices handled frequent use in challenging conditions, such as high humidity or low temperatures.

Special Features Testing

We explored additional features that could enhance usability. Night mode performance was assessed for quiet operation during sleep, while continuous drainage systems were tested for efficiency and ease of use.

Timer settings were verified to ensure they functioned as intended, and LED lighting or ambient lighting features were checked for practicality and convenience.

Overall Value

Finally, we compared the price of each model against its features, performance, and overall usability. This ensured that our recommendations offered the best combination of functionality and affordability, helping you make an informed choice for your home.

By considering every detail, we identified the top dehumidifiers that deliver excellent performance while staying within budget.
