    The GDDE25E Dehumidifier from Dimplex is an effective home dehumidification solution, capable of removing up to 25L of moisture per day. Maintaining optimal humidity levels through dehumidification is important in improving comfort levels, eliminating musty odours, preventing the growth of mould or mildew, and for other health reasons.

    The easy-to-use electronic controls let you adjust the relative humidity between 30% - 80%, plus there are three pre-set modes: Continuous, Living Room, and Bedroom. The unit will let you know when it’s time to wash the filter, which can be removed and cleaned with ease. There’s also a convenient 24-hour timer.
    24-hour timer

    This dehumidifier's 24 hour timer lets you set the appliance to automatically run at the most convenient time for you.

    Remove that unwanted humid, sticky air

    Dehumidifiers work by removing humidity from the air making your home more comfortable especially during the hot summer months. Thanks to the dehumidifying function that this air conditioner offers, you can avoid having to suffer in that sticky and heavy air, especially if you live in a poorly ventilated building or if you have any kind of respiratory-related health problems.

    Filter wash reminder

    The dehumidifier will let you know when the filter requires cleaning. This ensures that the unit continues working at peak performance.

    Adjustable humidity

    Electronic controls allow you to set your preferred relative humidity level, between 30%-80%. Three pre-set modes including continuous, living room, and bedroom, will suit your needs at the touch of a button.

    amazing performance for every room
    This has been such a game changer for a Melbourne winter in an older brick home. No longer do we deal with condensation on windows, mould on skirt and general mustiness. The rooms smell fresh and it is easy to use with a setting for living room, bedroom or continuous. It's been an eye opener how much humidity is in the home. We run it through the day as we have solar.

    Does the job, but it's really noisey, can only put it on when I'm out.

    Efficient and Easy to Use
    Purchased dehumidifier to stop my windows from being filled with condensation every morning and it has worked a treat. It is easy to move around from room to room as needed and the tray is simple to remove and empty. Have had little to no condensation since starting to use it. Just running overnight and have not seen a massive increase in my power bill.

    Questions & answers

    How do I clean the machine behind the removable filter section? Georgia · 2024-12-10
    Hello there; generally speaking, there should be no need to clean behind the removable filter, unless it has been left too long between filter cleanings. If this is the case, your safest bet would be to get the machine serviced by Dimplex. If you purchased the dehumidifier from us, please phone us anytime on 1300 000 500 and we can submit it to Dimplex on your behalf =) Or you can phone Dimplex Australia directly on 1300 556 816. Cheers, Adam from Appliances Online. AdamD, Appliances Online
