A filter for an electronics cooling unit of a telecommunications base station, the electronics cooling unit adapted to receive fresh air into a housing of the cooling unit through an opening communicating with the external environment. The filter includes a structural support configured to be mounted to said housing, a gasket sealingly engaging the structural support and adapted to engage the housing; and a filter media supported by the structural support, the filter media being free of a membrane type layer and including a fiber entanglement selected to prevent ingress of water sufficient to pass a salt fog test consistent with GR-487-CORE and in accordance with ASTM B 117.
