Abstract

In an air filter for filtering the intake air for internal combustion engines of motor vehicles, with a filter housing, which has an air inlet, an air outlet, and at least one water outlet disposed in the housing bottom, and with a replaceable filter matte disposed in the filter housing between the air intake and air outlet, in order to separate water particles from the intake air and in order to optimally discharge the separated water from the filter housing, a water separator is disposed upstream of the filter matte in the filter housing and means are provided in the at least one water outlet, which produce a water level in the water outlet of such a height that the vacuum in the filter housing acting on the water outlet is compensated for.
