I think a better way should be passing back to the view the filters in ViewBag. You can make something like below:

@Html.PagedListPager(
Model.Tasks, id => 
Url.Action("Index", new { id, 
Status = ViewBag.Status , AnotherFilterValue = ViewBag.AnotherFilterValue, ...  }))

But keep in mind to test ViewBag.Status for null value. If it does have a value put it in the route parameter list else set a default ActionLink.

Then inside the POST action you expect a nullable int like below:

public ActionResult Index(int? id, int? status, ...)
{
    int pageNumber = (id ?? 1);
    if (ModelState.IsValid)
    {

    using(var connection = new Context())
    {
        if(status != null)
        {
          ViewBag.Status = status.value;
          model.Tasks = connection.Tasks
                                .Where(task => task.Status == status.value)
                                .ToPagedList(pageNumber, 30);
        }
        else
        {
           model.Tasks = connection.Tasks
                                  .ToPagedList(pageNumber, 30);
        }
      }
    }

   return View(model);
}
