When people are indoors, breathing, talking, cooking, showering, etc. create moisture. Moisture - in a 4-person household up to 12 liters daily. In modern buildings, there is almost no natural exchange of air due to the insulation of walls and tight windows and doors. As a result, the air quickly becomes stuffy and stale. Moisture can collect in the building, increasing the risk of mold growth. Conventional window ventilation is not an alternative, as this causes valuable heat energy to be lost from the air in the room. The Air 4.0 stores this and uses it to heat the incoming fresh air.

The Marley Air 4.0 creates an optimal room air balance: Adapted to usage behavior and individual fresh air requirements, it ensures healthy, filtered room air at all times.
