I think this would work:

(setq org-export-filter-plain-text-functions
	(remove 'my-html-red org-export-filter-plain-text-functions))

Anyway, I recommend that you take a look at the documentation on filters
that Timothy pointed you to, as custom filters are tremendously useful
and versatile, and very "surgical". I use them a lot!

You can also apply a filter only in a document, by using the #+bind
keyword and including the function in a non-exportable code block:

#+begin_src emacs-lisp :exports results :results none
  (defun my-html-red (text backend info)
    (when (org-export-derived-backend-p backend 'html)
      (replace-regexp-in-string "@\\([^@]*\\)@"
				"<span style=\"color:red\">\\1</span>"
				text)))
#+end_src

#+bind: org-export-filter-plain-text-functions (my-html-red)

(You need to set org-export-allow-bind-keywords to non-nil)

Best regards,

Juan Manuel
