What to know before buying
Listing details to confirm
Listing details are inconsistent: one specification gives dimensions of 22.3D x 25.5W x 45.9H centimetres, while another gives H49.4 x W30.5 x D24.4cm. The listing also gives both one speed and high/low fan settings, and describes sleep mode as reducing noise without confirming how that relates to the listed 41dB level. Confirm the selected listing's details if these affect your decision.
Who is it for?
A good fit for
- Households seeking a compressor dehumidifier listed for rooms around 20m² to 30m².
- People who want a laundry setting and the option of hose drainage rather than relying only on tank emptying.
- Buyers who value app-based humidity monitoring and mode selection, subject to confirming smart-home setup details.
Less suited to
- Anyone who needs certain physical dimensions before fitting the unit into a tight space, unless the listing dimensions are confirmed.
- Buyers prioritising a demonstrably quiet bedroom appliance, as customer feedback on noise is mixed and the listed level is 41dB.

Customer feedback highlights perceived moisture removal and performance, with reports also noting compact size and appearance. Noise opinions differ, so the listed 41dB figure and sleep mode may not settle whether it will suit a noise-sensitive room. Feedback about extraction is useful context, but it does not establish a guaranteed daily output for a particular home.
Positive themes
- Customers report effective moisture removal and positive performance.
- Some customers appreciate the compact size, appearance and perceived value.
Mixed feedback
- Opinions on noise differ, with some customers finding it quiet and others considering it too noisy.
