I would like to know this for myself too. I know that Codeigniter has there own way of checking for html in there form validation class, if your using a form and XSS Filtering in there Security Class. It may not be the best but it should be able to help you until you find your correct answer.

I don't know how it is HTMLPurifier working, but it will be probably best solution than built-in XSS protection.
You can read more about the Codeigniter XSS vulnerability in this article. Maybe it is fixed in the latest version, but if you really want good protection, use something more powerfull than CI Security Class (you can build your own class).
