Get the Smart Control advantage

Smart Control is much more sophisticated that humidistats. It monitors the moisture levels in your home and controls the dehumidifier to prevent damp and condensation.

The biggest improvement in dehumidifier control systems this century

Smart Control automatically measures and remembers the humidity levels in your home. It then automatically switches on the dehumidifier when the levels start to rise and switches off when the humidity levels fall.

Over 100,000 Ebac customers have switched to Smart Control

Humidistats were once the only way to control a dehumidifier until Ebac invented Smart Control. Now customers choose automatic Smart Control over older humidistat controlled dehumidifiers.

The One touch and leave Smart Control to do the rest

Smart Control is far more convenient as it prevents constant manual adjustment and saves up to 30% wasted in running costs. Faster solution to the problem of damp and condensation with lower running costs.

Why you need Smart Control

The optimal level of humidity in your home varies throughout the day. The weather, temperature and moisture created from washing, cooking, and breathing all impact the relative humidity level. Smart Control tracks and varies the dehumidifier controls automatically to take account of all these variables so you don’t have to.

Designed for the UK climate

The 3850e is specifically designed for the temperate climate conditions of the UK. We have a unique climate – relatively mild and usually very wet with many variances from day to day. The 3850e’s heat exchange and air flow technology have been primed to handle these conditions and Smart Control handles the variable conditions with ease.

One touch control

Simple control system – every setting can be accessed with one touch of a button. Smart Control is the optimal way to control your dehumidifier.

5 Year Warranty

The 3850e has a 5-year warranty. Complete peace of mind for 5 years, and many more beyond that. Only available when buying direct with Ebac.

Adaptive extraction rate

Smart Control adjusts the 3850e to match the variable conditions in your home. Always taking out enough moisture to prevent damp and condensation, but not too much.

Air Purification

Remove pollen, pet hairs and bacteria with the air purifier setting. Choose from a carbon filter to remove odour and keep your home fresh or anti-bac that removes germs, bacteria and mould spores.

Hydrophilic coated heat exchanger

High water extraction per unit of energy consumed with Ebac’s specially designed heat exchange technology.

Low running costs

Reduces running costs by up to 32.4%. By learning about your home, we can optimise when the dehumidifier runs and reduce running costs accordingly.

Suitable for all house sizes

Removes exactly the right amount of moisture to stop and prevent damp and condensation problems in all UK homes

Fully enclosed water container

A large 2.5 litre, fully enclosed water container ensures no spillage, easy to empty and you won’t need to empty it every day.

Hidden water container

Integrated inside the unit. Easy to open, and integrated handle makes in easy to remove.

Changeable filters

Carbon, anti-bacterial and pollen filters help clean the air as we reduce moisture.

Slim & unobtrusive

Our slim profile fits against any wall in any room. With a depth of just 10.6 inches (26.5cm) and a width of 13.6 inches (34cm)

Dry Laundry easily

The 3850e can be used to dry laundry quickly and without damaging clothes. Use an Ebac drying to tent further speed up drying.

Electricity costs

Ebac dehumidifiers remove moisture in the air which makes your home will feel warmer, meaning you can turn down your thermostat by 1 degree and it will still feel the same temperature. The 3850e also emits latent heat from the heat exchanger. The combination of both these factors makes Ebac dehumidifiers almost energy neutral. The 3850e using Smart Control will only cost around £0.43 per day
