Abstract
The present invention comprises a filter housing having two or more layers of filters. Each layer is preferably spaced apart from each other so as to provide a chamber or gap between them. A port or vent is located within the chamber or gap between the two layers to provide an intermediate path for gas or liquid to flow through one layer of filter or membrane and out the vent or port for integrity testing.
