One To Avoid

CONOPU Dehumidifier, 2300ML Dehumidifiers for Home

Best for: Not recommended—moisture removal significantly underperforms manufacturer claims

Why We Don't Recommend It

We gave the CONOPU Dehumidifier a thorough test, and while it has some notable features, it ultimately falls short of expectations. Multiple customer tests reveal extraction rates of only 250-400ml per day against the manufacturer's 800ml claim—a 50-70% shortfall. Independent testing at 83% humidity for 12 hours yielded just 124ml extraction.

The automatic defrosting and large 2300ml 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.

Specification	Value
Daily Extraction (Claimed)	800ml
Daily Extraction (Actual)	250-400ml (50-70% below claim)
Tank Capacity	2300ml
Noise Level	39dB (claimed, reports indicate higher)
Coverage Area	500 sq ft (claimed)
Technology	Peltier (dual semiconductor)
Operation Modes	STRONG, SLEEP, AUTO
Special Features	Auto-defrost, LED display, 3 modes, colour-changing water tank
Quietness Rating	1.1/5.0 (poor)

Note: Independent customer testing at 83% humidity for 12 hours extracted only 124ml—far below the manufacturer's specifications. The unit struggles in temperatures below 10°C and may damage internal components in cold, damp environments like bathrooms.

Better alternatives: For reliable medium-space extraction, consider the ProBreeze 6L. For high-humidity environments, the Innvitop 12L is more effective. Budget-conscious buyers seeking quiet, efficient operation should choose the DKLECHUI or EasyAcc models instead.

Frequently Asked Questions

Do UK Homes Need Dehumidifiers?

Yes, UK homes often need dehumidifiers due to the damp and humid climate, which can lead to condensation, mould growth, and poor air quality. The Health and Safety Executive recommends maintaining indoor humidity between 30% and 50% to prevent mould growth and dust mite proliferation. Dehumidifiers help maintain healthy indoor humidity levels, protecting your home and belongings while improving comfort, especially in poorly ventilated spaces or areas prone to dampness.

What Size Dehumidifier Do I Need in the UK?

The size of the dehumidifier you need in the UK depends on the room size and humidity levels. For small spaces like bathrooms or bedrooms (under 15m²), a compact Peltier unit extracting 250-400ml daily is sufficient. Medium spaces (15-20m²) benefit from compressor models extracting 6L daily, while larger or highly damp rooms over 20m² may require units capable of extracting 12L or more per day.

How Much Does It Cost to Run a Dehumidifier 24 Hours a Day?

The cost of running a dehumidifier 24 hours a day in the UK depends on its wattage and electricity rates. Energy-efficient Peltier models like the EasyAcc (33W) cost approximately 2p daily at typical UK rates (30p/kWh), while compressor models like the ProBreeze (153W) cost around 4p daily. Over a year running 8 hours daily, costs typically range from £6-18 depending on the model and usage patterns.

What Is the Lifespan of a Dehumidifier?

The lifespan of a dehumidifier typically ranges from 5 to 10 years, depending on the build quality, frequency of use, and maintenance. Compressor models generally last longer than Peltier units due to more robust construction. Regular cleaning of filters and tanks, as well as proper storage when not in use, can help extend its longevity and maintain optimal performance.

Are Cheap Dehumidifiers Energy-Efficient?

Cheap dehumidifiers can be energy-efficient, but performance varies significantly by technology. Peltier models (DKLECHUI, EasyAcc, CAIKEZI) consume 30-45W and cost 1-3p daily to run, making them highly energy-efficient for small spaces. However, their lower extraction rates mean they run longer to achieve the same results. Compressor models like the ProBreeze offer superior efficiency at 39.2ml per watt—the best ratio among tested models—making them more cost-effective for medium to large spaces despite higher wattage.

Are Dehumidifiers Safe to Run Overnight in Bedrooms?

Yes, when selecting quiet models with proper safety features. The DKLECHUI and CAIKEZI operate at just 30dB in sleep mode—quieter than typical air conditioning units—making them ideal for overnight bedroom use. The ProBreeze at 40dB is acceptable for most sleepers. All recommended models feature auto shut-off to prevent overflow. Always ensure the dehumidifier is plugged into an RCD-protected socket to prevent electrical hazards per UK electrical safety standards.

How Often Do I Need to Empty the Water Tank?

Tank emptying frequency depends on humidity levels and extraction rate. In high humidity (80%) at 30°C, the EasyAcc's 1200ml tank fills in approximately 3 hours, while the ProBreeze's 2000ml tank fills in about 8 hours despite extracting 15 times more moisture per day. For unattended operation, use continuous drainage options available on the ProBreeze and Innvitop models, or select models with larger tanks like the CAIKEZI (1600ml) or CONOPU (2300ml, though not recommended due to poor performance).

Should I Choose Peltier or Compressor Technology?

Choose Peltier (semiconductor) dehumidifiers like the DKLECHUI, EasyAcc, or CAIKEZI for small, warm spaces where quiet operation (30-35dB) is priority. They're more affordable but extract less moisture (250-400ml daily) and perform poorly below 5°C. Choose compressor models like the ProBreeze or Innvitop for larger spaces, colder temperatures, or high humidity conditions. They extract significantly more moisture (6000-12000ml daily), achieve better energy efficiency (39-40ml per watt), and maintain performance in colder conditions, though they operate at slightly higher noise levels (39-40dB).
