More Info

The Stadler Form Theo air dehumidifier - simple elegance coupled with optimal performance

The Stadler Form Theo air dehumidifier can remove up to 10 litres of excess moisture in humid rooms in just 24 hours. Designed for superior performance and efficiency, it pulls moisture from the air, reduces dampness and condensation and helps with black mould and excess moisture in rooms up to 40 m(100 m3). 

3 selectable humidity levels let you create the perfect climate for health and comfort

Theo features an integrated thermostat that allows you to select between three levels of humidity (40, 50 or 60%). Alternatively, Theo can run continuously.   

Programmable on/off timer to dry your laundry at a low cost

Theo’s timer can be programmed with a delayed start of 1 to 7 hours or an operating period of the same time span. When the time finishes or the water tank is full, Theo switches off automatically.

Simply leave the timer on for a couple of hours and then can go about your business knowing that Theo will work at maximum capacity for the set amount of time and will then switch itself off. Your laundry will be dry when you get back and the timer setting will have ensured that you have used as little electricity as possible to dry your washing.

Energy-efficient design helps to reduce running costs 

With the very high air humidity, the dehumidifier should run continuously if possible. Thanks to Theo's hygrostat, the device is very energy efficient as it switches off automatically as soon as the desired humidity is reached. Thanks to the energy-saving design, Theo can extract up to 10 litres per day using only 280 watts of electricity.

The automatic shut off function for safety and permanent drainage feature for convenience 

Theo has been designed with safety in mind. When the internal water tank gets full, the unit will turn itself off.  

The air dehumidifier includes a continuous drainage hose should you want to leave the unit running for extended periods of time and avoid manually emptying the tank. This feature really comes in handy when you leave your house for a long period of time or want to reduce humidity in your shed, caravan, boat, or garage.

    Hidden ergonomic handle for easy carrying

    If you want to move Theo from one room to the other, its convenient handle makes the device easy to lift with one hand.

    Elegantly designed in Switzerland

    Besides being an excellent and powerful air improver that can effectively remove excess moisture and create an ideal indoor environment, its elegant and straightforward design fits in any room.
