Get filter_list() with filter_id() as key.

<?php
print_r
(array_flip(array_map('filter_id', array_combine(filter_list(), filter_list()))));
?>

Array
(
[257] => int
[258] => boolean
[259] => float
[272] => validate_regexp
[277] => validate_domain
[273] => validate_url
[274] => validate_email
[275] => validate_ip
[276] => validate_mac
[513] => stripped
[514] => encoded
[515] => special_chars
[522] => full_special_chars
[516] => unsafe_raw
[517] => email
[518] => url
[519] => number_int
[520] => number_float
[521] => magic_quotes
[1024] => callback

2 strings, but it's faster (-2 calls) and not the longest
<?php
$filters
= filter_list();
$filters = array_combine($filters, array_map('filter_id', $filters));
?>
also I use id's as values: $filters[$filter] - get filter id by name
