Wall or ceiling mounted hygro-adjustable valves for air exhaust inside buildings, more particular for high humidity places. When the air humidity becomes bigger, the calibrated hygro-sensitive strip will open the valve to enlarge its air passage which results in an increase of the air volume, when installed in a ventilation system with constant pressure regulation or ventilation unit with flat curve. When air gets more dry the valve will close to a more economic passage to reduce unnecessary air and heat losses.
