If you create your own filter, you can specify the key

app.filter('filterMaterials', function () {
  return function (materials, wood, plastic) {
     var filteredMaterials = [];
     for (var i = 0; i < materials.length; i++) {
          if (materials[i].type === wood || materials[i].type === plastic) {
          	filteredMaterials.push(materials[i]);
          }
     }
     return filteredMaterials;
  };
});

materials[i].type - the type key or materials[i]['type']
