Smart solutions are always welcome! It is particularly clever to use a single device to ventilate two adjacent rooms, such as a living room and bedroom.

In such a case the device should be installed in the living room. Suction takes place in the living room, while fresh air is directed into the bedroom via an additional adapter. Thus the bedroom air is always nice and fresh, and even if you are in the living room, the fresh air still travels there from the bedroom.
