There's an example in the documentation: https://docs.angularjs.org/guide/filter under 'Using filters in controllers,services and directives'

Snip from the docs :
" However, using a filter in a view template will reevaluate the filter on every digest, which can be costly if the array is big.

The example below therefore calls the filter directly in the controller. By this, the controller is able to call the filter only when needed (e.g. when the data is loaded from the backend or the filter expression is changed)."
