The unit switches on when humidity rises more than 5% above your chosen level and stops when it drops more than 5% below it.Continuous laundry mode keeps extracting moisture regardless of the humidity reading, making it useful when drying clothes indoors.Sleep mode operates the fan at its lower speed for quieter running.Inside drying mode provides another dedicated drying setting, while purify mode circulates air through the built-in filtration system to help capture dust and airborne particles.A helping hand with indoor laundryDrying clothes inside can quickly increase the humidity in your home, particularly when windows need to stay closed during colder or wetter weather.Continuous laundry mode keeps the dehumidifier running instead of stopping when the normal humidity target is reached. By continually removing moisture from the surrounding air, it can help create better conditions for clothes to dry indoors.It’s especially useful in utility rooms, spare rooms and other areas where wet washing can lead to condensation on windows, walls and other surfaces.Choose between tank collection and continuous drainageFor straightforward day-to-day use, extracted water collects inside the 7.5L tank. When the tank reaches capacity, the unit sounds an alert, shows the tank-full indicator and stops collecting water to help avoid overflow.For longer periods of operation, you can connect the supplied drainage hose to the rear of the dehumidifier and allow water to drain continuously.Continuous drainage is particularly convenient in areas with ongoing humidity, reducing the need to repeatedly remove and empty the water tank.Moisture removal with added air filtrationPurify mode lets the dehumidifier do more than simply remove excess water from the air.The filtration system combines PP, carbon and HEPA filtration to help capture dust and airborne particles as air passes through the machine. It’s a useful additional feature when you want to circulate and freshen the air while controlling humidity, although it should not be considered a substitute for a dedicated air purifier.Designed for flexible everyday useBuilt-in wheels make it easier to move the dehumidifier between suitable rooms as your moisture-control needs change.The 1.8m power cable gives you additional flexibility when positioning the unit, while integrated cable storage helps keep everything neat when it’s not in use. You can also use the 24-hour timer to schedule operation around your daily routine.For homes with children, the child safety lock helps prevent accidental changes to the controls.Automatic defrost supports reliable operation in cooler conditions. When the ambient temperature falls to 22°C or below and defrosting is needed, the compressor pauses while the automatic defrost cycle operates.Automatic shut-of - 40L Smart Dehumidifier with WiFi, Purify & Laundry Mode
