Use {$:filterStatus} construction:

angular.module('app', []).controller('ctrl',function($scope){
  $scope.data = [
    {name:'test1',b1:{lastValue:1},b2:{lastValue:6},b3:{lastValue:6},b4:{lastValue:0}},
    {name:'test2',b1:{lastValue:2},b2:{lastValue:0},b3:{lastValue:6},b4:{lastValue:0}},
    {name:'test3',b1:{lastValue:3},b2:{lastValue:0},b3:{lastValue:6},b4:{lastValue:0}}
  ]
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js">
</script>

<div ng-app='app' ng-controller='ctrl'>
  <input type='number' ng-model='filterStatus' ng-init='filterStatus=1'>
  <ul>
    <li ng-repeat='item in data | filter: {$:filterStatus}'>{{item.name}}</li>
  </ul>
</div>

var app = angular.module("Profile", []);
app.controller("ProfileCtrl", function($scope) {
  $scope.filter_val = {}
  $scope.data = [{
    name: 'test1',
    b1: {
      lastValue: 0
    },
    index: 'b1'
  }, {
    name: 'test2',
    b2: {
      lastValue: 6
    },
    index: 'b2'

<input ng-model="filterStatus" type="text">

your filterStatus should hold model value

ng-repeat = "d in data | filter:filterStatus"
