AngularJS - change $location silently - remove query string

try this

$location.url($location.path())

See documentation for more details about $location

You can always set the reloadOnSearch option on your route to be false.

It will prevent the route from reloading if only the query string changes:

$routeProvider.when("/path/to/my/route",{
   controller: 'MyController',
   templateUrl: '/path/to/template.html',
   //Secret Sauce
   reloadOnSearch: false
});
