Jambunathan is right.  Though, for completeness, I'll add that, as an
end-user, you shouldn't mess with `org-e-html-filters-alist'.  You can
add your filter to `org-export-filter-final-output-functions' instead.

Since this variable is back-end agnostic, your filter will probably have
to check the back-end first. Also, remember this is the functional
counterpart of hooks: the return value of your function will be used as
the new output. Thus, be sure it doesn't return nil.

Example follows:

#+begin_src emacs-lisp
(defun my-e-latex-final-filter (contents backend info)
  (if (not (eq backend 'e-latex)) contents
    ...
    modify contents
    ...
    new-contents))
#+end_src


Regards,
