Abstract
A pressure equalization element for a housing includes a water-impermeable membrane. The membrane is combined with either a pressure relief valve acting in two directions or with a corresponding combination of two pressure relief valves such that a volume of air exchange is reduced. An amount of moisture transported into the housing is thus also reduced.
