Connect through the Tuya app, Alexa or Google Home to check in and adjust settings remotely, or use the clear LED display when you’re nearby.Browse more options in our dehumidifier range.30L moisture removal for larger roomsWhen condensation, damp air or indoor laundry are more than an occasional problem, a smaller dehumidifier can struggle to keep pace.With an extraction rate of up to 30L per day, this compressor dehumidifier is designed for larger 25–35m² rooms. Use it in a big bedroom, utility room or other moisture-prone space where you need more capacity than a compact everyday model.The 4L water tank means fewer trips to empty the unit, while low and high fan speeds let you adjust the airflow around the job at hand.Not sure what capacity suits your space? Our dehumidifier buying guide breaks down the different options.Control the humidity from your phoneYou don’t need to be standing next to the dehumidifier every time the weather changes or the washing goes up.Connect it to the Tuya app to manage settings remotely or use compatible Alexa and Google Home voice controls around the house. It’s particularly handy when the dehumidifier is running upstairs, in a utility space or somewhere you don’t want to keep checking manually.The LED display keeps humidity and settings clear when you are using the controls directly.Four modes for more than damp daysHumidity changes with what your home is doing, so one fixed setting rarely covers everything.Auto mode lets you choose your target humidity. If the room rises more than 5% above the set level, the dehumidifier starts; once it falls more than 5% below it, the unit stops.Continuous Laundry mode keeps running regardless of the humidity reading, helping pull moisture from the air while clothes dry indoors.Sleep mode runs the fan at low speed for less disruptive operation.Inside Drying mode provides another dedicated drying option, while Purify mode circulates air through the built-in filter to help capture dust and airborne particles.For models designed around indoor washing, browse our Laundry Mode dehumidifiers.Help laundry dry faster indoorsContinuous Laundry mode keeps the dehumidifier working rather than switching off at the usual humidity threshold, helping remove that moisture from the surrounding air so clothes can dry faster indoors.It’s a practical option through wet weather, winter wash days or whenever outdoor drying isn’t realistic – especially in utility rooms and spare rooms where damp laundry can leave windows and surfaces covered in condensation.Tank or continuous drainageFor everyday use, let moisture collect in the 4L tank. Once full, the dehumidifier beeps, displays the tank-full icon and stops collecting water to help prevent overflow.In spaces that need longer periods of moisture removal, connect the supplied drainage hose to the rear of the unit and let the water drain continuously instead.That makes continuous drainage especially useful in consistently humid spaces where repeatedly emptying a tank would become a chore.Filter the air while you tackle moisturePurify mode gives the dehumidifier another job beyond extracting water.Air passes through the PP, carbon and HEPA filtration system, helping capture dust and airborne particles as it circulates. It’s a useful extra when you want to freshen the room while managing humidity, without presenting the machine as a replacement for a dedicated air purifier.Easy to move, easy to live withFour wheels make it easier to move the dehumidifier between suitable rooms as moisture problems change through the week.The 1.8m power cable gives you flexibility when positioning it, while cable storage keeps things tidier between uses. A 24-hour timer lets you plan operation around your routine, and the child safety lock helps prevent accidental setting changes.Auto defrost also protects operation in cooler conditions. When the ambient temperature drops to 22°C or below and defrosting is required, the compressor pauses while the automatic programme runs.Safety when the tank fillsThe full-water auto shut-off stops further collection once the 4L tank reaches capacity, helping prevent overflow.A child lock adds reassurance around busy family spaces, while the clear LED display lets you see the machine’s status without digging through menus.At 55dB, this is a higher-capacity compressor model rather than one we’d position as an ultra-quiet bedroom dehumidifier. Sleep mode reduces fan speed when you want less disruption.The Vonhaus PromiseTrusted by thousands of customers, with more than 20,000 reviews on Trustpilot.
