Good ventilation is not only important for your health. It also improves the effectiveness of the fireplace and the cooking hood, and reduces unpleasant odours and allergies.

Ventilation requires a ventilation system. This supplies fresh air via dry spaces (bedroom, living room). The air then flows via the hallway and staircase to humid spaces (kitchen, bathroom) where it is expelled by the ventilation system.

Four recognised ventilation systems exist that vary from fully natural ventilation to mixed ventilation and simple or dual-flow controlled mechanical ventilation (CMV). These systems are indicated with the letters A to D.

In addition, there are also individual appliances for decentralised ventilation[1]. These can be useful for purifying the air in usually humid areas such as the bathroom, kitchen or storage room.
