Views: Show current user-entered filter
You can use the PHP text filter in core. It is quick and dirty.

Add a Header of global text area to the view. Then add this PHP code using the PHP code text format:

&lt;?php
$query_params = drupal_get_query_parameters();
if (isset($query_params['title'])) {
  print t("Results for @query", array('@query' =&gt; $query_params['title']));
}
?&gt;


Exposed filter and sort queries in views are passed as query parameters in the form of:  

?title=test


In the above code I am just looking at the parameter 'title', but you can adapt that code snippet to suit your needs. Just look at your url to see what query parameters are passed along.
