Newbie, please be gentle on me

Hi all, 

I'm trying to setup the htmlpurifier plugin for code igniter for a new project I am involved in and would like to get it to filter down to just displaying plain text, taking out all of the tags, etc... 

So far I've got the below; what else do I have to do? 

case 'plaintext':

$config = \HTMLPurifier_Config::createDefault();

        $config->set('Core.Encoding', $ci->config->item('charset'));

$config->set('iString',true);

$config->set('AutoFormat.AutoParagraph',false);

$config->set('AutoFormat.Linkify',false);

$config->set('AutoFormat.RemoveEmpty',true);

break;
