You can use beforequery:

    Ext.create('Ext.form.ComboBox', {
        fieldLabel: 'Filtered Cities',
        store: cities,
        queryMode: 'local',
        displayField: 'name',
        valueField: 'abbr',
        renderTo: Ext.getBody(),
        listeners: {
            beforequery: function(queryEvent){
                cities.clearFilter(true);
                cities.filter({
                    property: 'state',
                    value: 'AK'
                });
            }
        }
    });
