Filter in Laravel showing BadMethodCallException

I have a collection from below query

$order = $company->Orders()
            ->whereBetween('created_at', [$this->start_date, $this->end_date])
            ->whereNull('is_cancel')
            ->whereNull('is_removed')
            ->whereNull('deleted_at');

Now I want to filter out all the orders who are expired

$orders = $orders->filter(function($value,$key){
                return  $this->expiry($value) < Carbon::now();
            });

above code is throwing error

BadMethodCallException with message 'Call to undefined method Illuminate/Database/Query/Builder::filter()'

I can use $orders->get()->filter() but I need to check furthur in the collection for counts and mapping etc, so I dont want to use get here. Any help is much appreciated.
