WordPress – display the page content without wrapper

How to display the content for given page ID withot the <p></p> wrapper?

The method I’m currently using is:

<?php
$id=21;
$post = get_page($id);
$content = apply_filters(‘the_content’, $post->post_content);
echo $content;
?>

For example page ID = 21 has the following content: “Some content”

What the wordpress echo is

<p>Some content</p>

Any suggestion much appreciated.
