A venting system for a container and the overall container assembly that uses the venting system is claimed. A container and a lid are provided. The lid of the container defines a venting port for equalizing gas pressure within the container. A support platform is placed over the venting port. The support platform defines a plurality of holes. Placed in each of the holes is a filter element. The filter element is made of a porous sintered powder metal having a pore size of no greater than five microns. In this manner the filter elements enable gas to vent to and from the container, yet the contents of the container are prevented from passing through the filter elements should the contents of the container touch the filter elements.
